Startup Boilerplate: What It Is and How to Pick One

Prince — Fri, 17 Jul 2026 06:24:21 +0000

A startup boilerplate is essentially a pre-written codebase you clone or purchase to avoid redoing everything from scratch each time you launch a company. User registration, payment gateway integration, database, and emails – you will get all of them done for you. This way you can focus on the code that actually brings something special to your startup.

The term itself comes from journalism and newspaper production. In order to reduce costs, newspapers used standardised metal plates to print articles and stories that would run the same way in every issue. Software adopted the term for similar reasons – code that is written once and reused instead of being rewritten each time.

What a Startup Boilerplate Actually Includes
Depending on the particular boilerplate you use, its feature set may vary. However, some common features include:

User sign up, login, and password reset

Payment processing, usually through Stripe

A database already connected and structured

Basic UI components for your dashboard and landing page

Deployment configuration so you can ship without guessing

More elaborate versions have team accounts, roles and permissions, email templates, file uploads. The more there is included in the boilerplate, the less you'll have to develop yourself. However, it also means that more decisions were made for you by default, which is always a compromise.

Why It's More Important for Startups than for Enterprises
While an enterprise could afford a whole month for setting things up, a startup could not. Every week invested in building authentication screens and Stripe webhooks is a week that could be used for interacting with customers and adding that extra feature that would make people actually pay for it.

The founders who miss this math will end up developing the same authentication flow that every other startup developed in that year. This work adds absolutely no value to your business. The only person for whom it does have value is a creator of the boilerplate you did not use.

Free Boilerplate vs Paid Boilerplate
And now we get to the point where you actually have to make a choice.

While free boilerplates offer access to full codebase without license fees, paid boilerplates allow you to leverage someone else's work and expertise on that. In other words, you can see every single line of code for free boilerplate but you won't have much support after the initial setup. If something goes wrong – nobody will explain you what has happened, especially if the developer behind the boilerplate project is inactive at the moment.

Paid boilerplates usually cost you once or monthly and come with additional functionality pre-installed – multi-tenancy, admin panels, billing flows. Also you pay for someone else's time spent on solving those problems.

How Do You Actually Choose One?
4 questions, in order of importance:

What do you need your product to actually do on day one? Don't overpay for multi-tenancy if you're writing a single-user app. Don't underpay for it if you're writing something for teams.

What stack are you familiar with? A boilerplate on a framework you know saves you a lot more time than one on a framework you'll be learning in a month.

Is it maintained? Check the date of the last update and the changelog. An unmaintained boilerplate, even if its demo looked nice, is an unnecessary risk to take.

Can you look into the code yourself or do you have to trust reviews? Open-source boilerplates give you the ability to evaluate their quality. With a closed-source one, you have to trust the authors instead.

A Word of Caution on AI-Generated Boilerplate
Nowadays, it is possible to generate a working application out of a simple English description using an AI tool. And while it's incredibly fast and useful for prototyping, research up to 2026 points at one drawback – the AI-generated code tends to accumulate more technical debt per line than a professional developer's code.

And that is because there is no architectural review done to AI-generated applications, and no maintenance of any kind. While a boilerplate made by a human and maintained by a human has passed all the tests needed in the real world environment multiple times.

Startup Boilerplate Comparison: What the Top Options Actually Include
Talk is cheap. Here is what real startup boilerplates include, based on their own documentation and pricing pages.

A few honest notes on that table, since a comparison only earns trust if it admits tradeoffs.

Kostra's authentication is done internally. This allows avoiding the per-user fees of using some third-party auth provider and does not require you to depend on another company's uptime. However, the disadvantage here is that all the security is now on you.

ShipFast's advantage is in its affordable price and large community of users. The product does not offer multi-tenancy and admin panel, so in case of development for companies, these features should be added.

Both MakerKit and Supastarter are more expensive options than the others on the list but also deserve their price because of having a more complicated and advanced multi-tenancy solution. Moreover, both frameworks have already been used by many projects, which means that their architecture should be studied before work.

Finally, an open-source product is totally free, and you can see every code of it without paying anything. Of course, you will need to install it manually and will have no access to a support hotline in case of any troubles at night.

All of the products above are great in their own way. They help founders of different kinds of apps to cope with some challenges in development.

Why Founders Use a Self-Hosted and One-Time Payment Approach
In this section, I will explain why Kostra has been built the way it was designed. In other words, I will tell what is the real reason for the above-mentioned claims of the founder.

There are no subscription taxes. Some boilerplates in this market have changed their prices to annual ones. In other words, your product becomes a source of constant income for your company.

No dependency on the third-party auth providers. As soon as you have some login system based on the third party, it is obvious that you become dependent on them. Thus, you inherit all their decisions in terms of price, outages, etc.

Stack known by developers. Both PostgreSQL and Prisma do not require your development team to learn any new technologies to start working.

These are the real reasons for choosing this model for the product. Of course, it is not the only way of development, and Kostra may not suit everyone.

Common Mistakes Founders Make When Picking a Boilerplate
There are some common mistakes I've seen many founders doing while selecting the boilerplate. Let me name them explicitly.

Choosing it based on marketing, rather than a demo. Marketing page doesn't say anything about the code. Clone the repository, or at least, visit the demo site, before buying the tool.

Not looking into the maintenance schedule. Visit the changelog of the product. No updates within eight months? This means you will need to maintain the boilerplate yourself in the nearest future.

Overbuying based on current needs. Multi-tenancy, role-based access control, and audit logging is great for a B2B application aimed at enterprise clients. It's absolutely useless if you're trying to validate your basic B2C application.

Underbuying and then hitting a wall in the third month. Just the opposite situation. Basic, single-tenant boilerplate will work perfectly for fast prototyping, but the first request for another user's account in your product will force you to do the refactoring yourself.

Forgetting about licensing terms. There are boilerplates that limit your usage to one project only. And there are tools that can be used for any number of projects. If you're an agency or a serial entrepreneur, it's a difference in the price.

How to Actually Test a Boilerplate Before You Commit
Here is a list of actions that will tell you more about the product than general advices about how to do research.

Clone it and run the code locally. Fifteen minutes will give you much more information than an hour of reading about the boilerplate.

Study the authentication code. It's usually the most critical part of the boilerplate because of security reasons. Unclear code here means a warning sign.

Visit the Stripe integration and check if it handles all edge cases. Do they process failed transactions, subscription cancellations, and plan upgrades? Or do they handle only the happy case of the purchase?

Visit their community/support channel. One-day reply will show you that someone still supports this project. Lack of replies says the opposite.

See what kind of applications were built using it. Every boilerplate provides the list of sample projects. Go to several of them and see if they work.

Signs a Boilerplate Is Overselling Itself
All marketing pages for boilerplates look the same. "Shipped in days, not months." "Saved 40 hours." Some of that is accurate. Some of that is pure copywriting working harder than code.

A few red flags worth looking out for that will help you discern between honest and misleading boilerplates:

List of features that don't show any code. If the marketing page says it does some fancy things, but never once demonstrates how, there is a reason. A decent boilerplate maker shows the code behind their claims.

Testimonials that have no product. Saying "this saved me weeks" is nice, but you should be able to find the actual product that used it. Find boilers that name the product they made.

Ambiguous pricing pages. If you can't find the exact one-off or subscription price without writing an email to the company, then that is unnecessary friction. Good boilerplate marketing pages, either paid or free, will tell you the price on the first screen.

Lack of changelog/roadmap. An active boilerplate maker releases regular changes and shares updates publicly. Lack of those is an indicator of a project becoming inactive, although its marketing pages might not reflect that.

None of this guarantees that a slick-looking marketing page is not a good boilerplate, but it proves that slickness is not proof of quality. Code, changelog, and real-world examples prove that.

What startup boilerplate does is bet on saving developers time on non-profit-generating features. Authentication, billing, and initialization are common problems for almost all businesses. Someone has found an optimal solution for those common problems multiple times.

The boilerplate I would recommend to founders who want self-hosting, a one-time fee, a Postgres and Prisma stack they already know is Kostra. If this isn't your cup of tea and you lean towards another solution from the list above, it's still good news.

What is the difference between a startup boilerplate and a SaaS starter kit?

No difference at all! The terms are equivalent. Both mean a pre-built codebase with auth, payments and database integrated so that you don't have to spend time setting things up.

Do I own the code in a startup boilerplate?

Yes. Most of the boilerplates provide you with the whole source code. You can modify it, change it and deploy it as your own application. What you buy is a base which you will be able to transform into your product.

Is it possible to use a boilerplate for more than one project?

This depends on the license type. The majority of the boilerplates offer per-developer licenses, meaning that once you purchase a license, you may use it for all projects you develop. Team licenses might cost more but allow for sharing the codebase across the development team.

How much time does it take to start working on a boilerplate?

Assuming that you are talking about a paid boilerplate with reasonable documentation, in less than an hour you will be ready to work locally and in one day you will be able to deploy it.

Are free open source boilerplates sufficient for production?

Yes, they are. Our free open source boilerplate, BoxyHQ, is completely production-ready for enterprise identity use cases. The only tradeoff would be in documentation quality and support.

What would happen if Next.js or Stripe would release a new major version?

In case of paid boilerplates with an active author, the author would usually update his/her boilerplate. Otherwise, you would have to update everything by yourself. This is one of the reasons why people pay for their boilerplates.

How can I tell if the boilerplate is still maintained?

The best way is to see the activity in GitHub. If commits were made in the last 30–60 days, then the project is alive. You should also pay attention to the response rate in case of open issues. It means that the author is willing to help but just doesn't make changes often enough.

Prisma vs Drizzle: Which ORM Should You Use in 2026?

Prince — Mon, 13 Jul 2026 09:20:40 +0000

Kostra's whole data layer was built using Prisma. However, prior to settling on that solution, we had run real-world migrations and write operations via Prisma and Drizzle on a single PostgreSQL database.

Here's what the benchmark revealed about the two ORMs, along with the developments since 2026 in each of them that may be helpful in making a decision which one to choose for your projects.

TL;DR if you're in a rush: Choose Prisma when a mature ecosystem, visual data browser, and SQL abstraction are what you need. Choose Drizzle when you prefer to stick closer to SQL, need a minimal bundle size, or deploy to the edge

Both solutions are production-ready. There's no wrong choice, just the one that fits your project more.

What Each ORM Actually Is
Prisma is schema-first. You design your data model in a .prisma file by using Prisma's schema language and after that run prisma generate to get a fully typed client for querying. Prisma Migrate will automatically migrate your schema changes into SQL migrations.

Drizzle is code-first. You create your tables natively in TypeScript using the query builder which is similar in structure to SQL. There's no separate schema file and no generation step. Change a table definition, save the file, and your types update immediately.

That single difference, schema file plus generation step versus TypeScript-native with none, is the root of almost every other difference between them.

Schema Design and Developer Experience
The Prisma schema looks almost like normal English. Type definitions, relationships, and constraints are all defined in one declarative code block. The Prisma VSCode plugin further provides features like autocomplete, quick fixes, and definition navigation above this. However, the problem is the generation process. Any changes to the field require a separate prisma generate command for the application to reflect those changes.

With Drizzle, the generation step is skipped entirely. You can work with your schema directly as a TypeScript module, and types will be updated instantly when you save your file. The catch is reversed as well: table definitions with Drizzle feel more like SQL-DDL than data modelling, which may suit some teams just fine but not others.

Performance and Bundle Size
Here was where the story changed in 2026. For years, the main problem was the Rust engine for Prisma's queries; it was a big, heavy binary that caused extra cold-start latency when deployed to serverless and edge systems. In contrast, Drizzle's lack of engine layer meant it was always faster and had a much smaller payload.

Prisma 7, which was launched at the end of 2025, had done away with its Rust engine and adopted a new implementation in TypeScript and WebAssembly. This meant smaller bundles and native edge runtime support was now available. Thus, the gap in cold start performance that made Drizzle such a clear winner was significantly reduced.

The gap never closed. Drizzle remains the smallest payload, with its bundles measuring in kilobytes compared to megabytes of Prisma bundles. Drizzle also has slightly better cold-start performance than Prisma in benchmarks up until 2026. However, for typical backend systems that run on a persistent server or container and not an edge system, database round-trip times completely overshadow the overheads of ORMs.

Migrations and Tooling
Prisma Migrate creates SQL migrations automatically out of changes to your schema, while Prisma Studio allows you to browse your data visually without any configuration. This tooling is superior compared to Drizzle's similar offerings, drizzle-kit generate and drizzle-kit migrate. While those are very powerful and easy to use, they sometimes require manual SQL migrations in case of changes that cannot be done automatically, such as renaming columns.

However, if migration tooling and database graphical user interface are important parts of your development workflow, then Prisma wins in 2026 in that regard. As long as you're okay with manually writing SQL migrations in case of generator inability, Drizzle should not hold you back.

Ecosystem, Maturity, and Community
Prisma comes with more history and a richer ecosystem - more answers on StackOverflow, more tutorials, more people who have hired someone who knows it. Prisma is the ORM that is included in SvelteKit and Remix in their official documentation, and it is the default suggestion for a fast onboarding of a new team member.

The adoption of Drizzle quickly accelerated during 2025 and 2026. Drizzle is currently used in production at companies like Replit, Sentry, and Figma; Astro created its own Astro DB based on Drizzle; and the Hono.js framework recommends it as a default ORM. By mid-2026, various reports noted that the weekly downloads of Drizzle from npm were getting closer to Prisma’s and even surpassed them in some reports, although each of the ORMs was counted under a different package name (drizzle-orm versus @prisma/client and prisma CLI). In any case, the general trend seems to be switching from Prisma to Drizzle rather than vice versa.

One important development to note: PlanetScale employed the core team behind Drizzle in 2026 to develop the ORM. While Drizzle itself is still open-source, it was an important decision regarding sustainability since it addressed the question of where the money for development would come from. Prisma, in turn, is a venture-backed company with a free ORM that helps people adopt other paid tools from their ecosystem such as Prisma Accelerate and Prisma Postgres.

Comparison Table

Which One Did We Pick for Kostra, and Why
Kostra is built on top of Prisma using PostgreSQL. There are three particular reasons why we chose it specifically for our boilerplate:

Prisma Migrate guarantees consistency in all projects based on the boilerplate concerning schema changes. Second, the schema itself is the quickest way for any new developer to grasp the whole data model at once. The fact is significant because Kostra is a boilerplate, meaning others will build upon it. Third, our layered architecture separates the ORM from the rest of the application through a repository pattern, It means that in case Kostra was going to provide an alternative driver such as Drizzle in some future release, there will be changes only in one layer.

The straightforward bargain: The benefits provided by the smaller package size and quicker warm-up time of Drizzle will be more significant when deploying Kostra for edge environments. It doesn't. Kostra ships with Docker and Docker Compose for running on their own and in containers, which becomes a valid choice for which the “cold start” factor is not much of an issue anymore. If your own product is built with the edge in mind, then the logic behind that may lead you to Drizzle even within the Prisma boilerplate code.

Kostra isn't the only Next.js SaaS boilerplate built this way. The official Vercel starter and the ixartz SaaS Boilerplate both ship with Drizzle instead, which is worth knowing if ORM choice is a hard requirement for your stack.

How to Choose: A Simple Framework
Pick Prisma if:

Your developers lack comfort using SQL and you need abstraction that helps write the correct query

You need Prisma Studio for visualization of your database without extra configuration steps

You are looking to hire people who are proficient with the ORM of choice

Your application runs in a persistent environment like server/container where there is no such thing as cold starts

Pick Drizzle if:

Your developers prefer working with SQL and you don’t want the ORM to get in their way

You deploy your app to an edge runtime like Vercel Edge Functions or Cloudflare Workers where bundle size matters

You don’t want any generation step in your development workflow

You are running your database on Neon, Turso or PlanetScale all of which provide excellent support for Drizzle driver

If none of that settles it, look at your database requirements against your actual stack before the ORM choice, not after. The ORM should follow from your deployment target and team's SQL comfort, not the other way around.

Frequently Asked Questions
Is Drizzle faster than Prisma?
In terms of bare ORM overhead and startup time, yes, Drizzle is still faster because it does not have an extra layer of query engine to start up. Prisma 7 brought down that margin substantially by switching from Rust engine to a more lightweight TypeScript and WASM engine. For applications that use server-side persistence rather than serverless functions, the difference becomes negligible, as the execution time of the database queries always will be dominant.

Can I switch from Prisma to Drizzle later, or the other way around?
Yes. It is possible to switch between Drizzle and Prisma after a while? Yes, but allocate some time for it. Ultimately, both ORMs produce the same SQL migrations to the same PostgreSQL tables, so your data will be unlocked. The thing that consumes time is rewriting every query in the application layer to the different ORM API. It becomes easier when teams follow a repository pattern and have all database queries under one single internal interface.

Does Prisma work on the edge now?
Yes, since Prisma 7, which came out later in 2025. Prisma versions before then required a Rust binary that did not support edge runtimes such as Cloudflare Workers, making this the clearest strength of Drizzle for several years until Prisma 7 introduced its TypeScript/WASM engine. However, Drizzle’s compactness remains an advantage where size is critical.

Which ORM should a solo founder pick for a new SaaS project?
If you haven’t used either before, then you should start with Prisma’s schema file and auto-generated client because of how much easier it is to use and because there are many more tutorials and SO answers. If you know how to use SQL well, then Drizzle will not waste your time.

Do Prisma and Drizzle both support PostgreSQL?
Absolutely, as both are fully compatible with PostgreSQL, MySQL, and SQLite. Prisma also supports SQL Server and MongoDB, something that Drizzle doesn’t support. If your project requires you to use MongoDB, then the decision becomes pretty clear on its own.

Bottom Line
Both ORMs are truly production-ready in 2026, and the difference between them has been narrowed from both sides: Prisma became lighter and edge-enabled, and Drizzle became more feature-rich. The better choice is based on how comfortable your team is with SQL and where your application really runs, not which ORM comes out ahead in the benchmarks.

Kostra Ships with Prisma and PostgreSQL baked in to a layered architecture right out of the box, alongside auth, Stripe billing, and file storage, so you’re not cobbling any of that together yourself. Compare it against other Next.js boilerplates to see how the rest of the stack holds up.

Vercel Starter Kit: Best Templates to Deploy Your SaaS Fast

Prince — Fri, 10 Jul 2026 11:55:33 +0000

I looked at Vercel's template page myself and will give you exactly what it includes, be it free or not.

Vercel operates the marketplace of templates located on vercel.com/templates. One can deploy any template there in one click. Some of them are officially supported builds from Vercel, the others are community contributions. The gap between them in terms of quality is very big, so one has to know what is what before deploying.

What Are the Actual Features Included in Official Vercel Starter Kits
Vercel develops the "Next.js SaaS Starter" template itself. It has more than 15,500 stars on Github. It includes:

JWT authentication manually implemented, without using any third-party provider for that purpose

Stripe Checkout integration for subscription billing

Access control based on role with Owner and Member roles

Dashboard for managing teams

Activity logging

Middleware for protecting routes

Underlying tech stack includes Next.js, PostgreSQL, Drizzle ORM, shadcn/ui and Tailwind CSS. These technologies form the stack recommended by Vercel and therefore they stay pretty close to the recommendations of the Next.js team.

There is one more template provided by Vercel, called the "Minimal Next.js SaaS Website Starter". As the name implies, it includes only Tailwind and dark theme support and nothing more. It can be used for building landing pages, but not for whole SaaS application.

What Is Missing in Official Templates
This part is often omitted in reviews of Vercel starter kits, but I will discuss it because Vercel's official SaaS starter clearly mentions this on its own page saying that it is a learning resource and not a production toolkit with other paid and more featureful alternatives available in the community.

It is an honest thing to say, so take it into account when picking up the starter. The official Vercel SaaS starter template does not provide:

Multi-tenant functionality or organization management, only basic Owner/Member roles

E-mail sending either transactional or bulk

File storage and uploads

CMS/blog module

Additional admin tools except those basic

If your SaaS requires any of these features then you will have to build them yourself on top of the starter.

How to Actually Deploy the Official Vercel SaaS Starter
And now comes the real step-by-step guide on how to deploy the starter from Vercel. It is different from the marketing version.

Clone the template repository. Deploy on Vercel templates page or clone the repository and use it locally first.

Set up your database. The starter relies on Postgres with Drizzle ORM. So you will need the connection string from Vercel's own Postgres offering, Neon, or Supabase.

Configure Stripe locally. Stripe webhooks will be listened locally using the Stripe CLI for testing purposes until deployment.

Create a production webhook. When everything is ready for deployment, you should go to your Stripe dashboard and create a production webhook pointing to the URL of your API route. For example, it may be something like yourdomain.com/api/stripe/webhook. Choose the events you want to process there. Usually, it is checkout.session.completed and customer.subscription.updated.

Deploy to GitHub. Just push your code and link the repository to Vercel.

Test everything. Register a test user, go through a test subscription process in Stripe's test mode, and ensure that the webhook correctly updates your database.

All these steps are quite easy if you are familiar with them, but for beginners the process of creating a Stripe webhook will take some real time. This is the place where people usually get stuck, since local testing is different from production behavior.

Community Templates in Vercel Marketplace
Except for the official starter there are dozens of community templates listed in the Vercel marketplace. Let's consider three of them in more details.

Saasfly
It is a full-fledged open-source SaaS solution that is more featureful than the minimal official starter. This is a template for developing the actual product and not just a reference implementation, so it contains more elements that will have to be built from scratch otherwise.

Stripe & Supabase SaaS Starter Kit
This template uses Supabase for the authentication layer and Drizzle ORM with Postgres for database and Stripe for subscriptions. The authentication layer supports OAuth and password reset out-of-the-box.

Setting up Google or GitHub OAuth will require creating credentials in Google Cloud and GitHub developer settings and adding client ID and client secret to the environment variables. This template is perfect for those who already use Supabase as the base for their infrastructure.

Auth0 SaaS Starter Kit
This template is designed for B2B SaaS solutions that require the advanced authentication layer provided by Auth0 by Okta instead of the manually built system. The tradeoff here is that while setting up the starter becomes slightly harder, the authentication layer gains such enterprise-grade features as SSO, which become important when selling the product to the companies and not to the individuals.

Community templates may differ greatly in terms of freshness and maintenance. Some of them are one-man projects and were abandoned some months ago. Check the last commit date on GitHub before starting development based on it. A template with no commits during half a year is a risky choice, even if the demo looks great.

Vercel Starter Kit Comparison Table

Free templates will help you get started quickly. The price you pay for that is the need to implement additional components from scratch after some time, when you will require team accounts, file storage or e-mails.

Common Questions About Vercel Starter Kits
Are there open-source SaaS templates that combine Prisma, Postgres, and Stripe under a permissive license? Most of Vercel's own templates use Drizzle ORM, not Prisma. If Prisma specifically matters to your stack, you'll find more Prisma-based options outside Vercel's official marketplace, including several free GitHub boilerplates and paid kits like Kostra.

What are the most active Next.js SaaS starter repos right now? Activity changes fast enough that "most active" is a moving target. The safest check is the GitHub commit history and issue response time on whichever repo you're considering, not a ranked list someone wrote months ago.

Can I use any database with the official Vercel starter? Yes. The template is built around Postgres, so any Postgres provider works, including Vercel's own offering, Neon, or Supabase's Postgres service.

Vercel Starter Kit vs a Full SaaS Boilerplate
This is the real decision. A Vercel starter kit gets you a working pattern fast, usually free. A paid SaaS boilerplate like MakerKit, ShipFast, Supastarter, or Kostra gets you more of the business logic already built: multi-tenancy, email, file storage, and ongoing updates from a maintainer whose job is keeping that codebase current.

Neither is wrong. It depends on how much you want handed to you versus how much you want to build yourself.

Pick a free Vercel template if:

You're learning the Next.js App Router patterns

Your SaaS is simple, no teams, no complex billing

You have time to build auth, email, and storage yourself

Pick a paid boilerplate if:

You need multi-tenancy or team accounts on day one

You want email, file storage, and billing already wired together

You'd rather pay once than spend weeks on setup

Where This Leaves You
Vercel's own starter is a solid, honest reference. It even tells you when you've outgrown it. If you hit that point, that's exactly the gap a full boilerplate like Kostra is built to close, with auth, Stripe billing, and file storage already connected in one Next.js codebase.

Start free. Upgrade when the missing pieces start costing you more time than a boilerplate would.

Frequently Asked Questions
Are Vercel starter kits free?
Yes. All official Vercel templates are free and open source. You pay for Vercel hosting separately, but most small projects can fit the Vercel free tier.

What is the difference between Vercel template and Vercel starter kit?
Vercel uses both terms interchangeably on the same page. Starter kits usually contain more configuration (auth, database, payments) than basic templates, which are mostly UI shells. But the names are not consistent, so you should look at the feature list.

Does the Vercel SaaS starter contain a database?
Yes. The official Next.js SaaS Starter is built around Postgres via Drizzle ORM. It isn't locked to a single provider — Vercel's own Postgres offering, Neon, Supabase, or any other Postgres host all work.

Can I deploy a Vercel starter kit to a non-Vercel host?
Yes. The code is just standard Next.js. You can deploy it to Railway, Render, Fly.io or any other host that runs Node.js. One-click deployment button is specific to Vercel only, but the codebase is fully portable.

Is the Vercel Platforms Starter Kit suitable for regular SaaS?
No. It is designed for multi-tenant applications, where users need subdomains or custom domains. For a regular single-tenant SaaS application, Platforms kit adds unnecessary complexity.

What is the best Vercel starter kit for a solo founder deploying a SaaS?
For a simple product, the Next.js SaaS Starter will be a perfect fit to implement authentication and Stripe billing in the App Router. For a more complete production-ready solution, a boilerplate will cover the gaps left by Vercel starter.

React SaaS Boilerplate: Best Options in 2026

Prince — Thu, 09 Jul 2026 10:39:54 +0000

I've built SaaS products from scratch and from boilerplates. The from-scratch approach always costs the same thing: three to six weeks wiring auth, Stripe, email, and a database layer before you even start building product features.

A good React SaaS boilerplate cuts that down to a day or two. A bad one costs you three weeks, but spent in debugging someone else's hacks.

This article talks about the best React SaaS boilerplates in 2026. Almost all of them use Next.js under the hood, because Next.js is where all the production React happens nowadays. I'll talk about what each boilerplate offers, what it costs, and who it suits. No affiliate links. Just straight-up trade-offs.

What a React SaaS Boilerplate Should Have in 2026
First, here's how to immediately filter boilerplates out. The bar has been raised. In 2026, if a boilerplate offers just auth and Stripe checkout forget it, you're not saving much.

Here's what needs to come bundled with a boilerplate today:

Authentication with multiple methods. email and password, Google OAuth, magic links. HTTP-only JWT cookie based session handling as default
Payments beyond checkout. Subscriptions, one-time payments, customer portal. With webhook handling.
A real database layer. Typed ORMs such as Prisma or Drizzle running on PostgreSQL. No JSON files. No "bring your own".
Role-based access control. If you're building a B2B app, you'll need roles right away. Trying to implement RBAC retroactively is extremely painful.
Transactional email. Password reset emails and invoices, integrated into a dedicated service such as Resend or AWS SES.
File storage. Uploading files to S3 or R2, abstracted in a reusable way.
A maintainable structure. Layered architecture beats dumping everything in a bunch of files. You'll be living in this codebase for years.

And there's one hidden metric: the date of the last commit. The Next.js ecosystem moves quickly. If you see a boilerplate that hasn't seen an update in 8 months it will have a hard time keeping up with every dependency you have to include.

The Best React SaaS Boilerplates in 2026

Kostra - Best overall for production-grade architecture Price: $150 one-time | Stack: Next.js App Router, Prisma + PostgreSQL, Stripe, Tailwind CSS

Full disclosure: Kostra is our product. But the reason why we made it is the same reason why it stands above everyone else. Most boilerplates are demos wrapped in price tags. They work until your first real feature request comes along and then fall apart architecturally.

Kostra is architected as the kind of software a team would maintain over years:

Layered architecture. Services and repositories are decoupled. The business logic isn't mixed with the route handlers. Swapping a provider or adding a new feature only requires changing a single layer, not twelve files.

Auth implemented properly. HTTP-only JWT cookies (not localStorage tokens), Google OAuth, and magic links included.

Stripe covered in its entirety. Subscriptions, one-time payments, customer portal, webhook handling.

Drivers configured. Storage works out of the box with AWS S3 or Cloudflare R2. Email with Resend or AWS SES. Change providers with configs, not rewrite.

Centralized role-based access control (RBAC). Roles and permissions enforced in a consistent way.

Everything else in the stack: Docker configuration, Zustand as a state manager, Atomic Design components based on Tailwind CSS, blogging system, and an admin dashboard.

For: Developers and founders who intend to work with this codebase in year two. If you want a foundation, not a demo, this is the one.

Against: Kostra is opinionated. If you want to remove Prisma and replace it with Drizzle, or JWT with a hosted auth service, you're swimming against the tide.

ShipFast - Best for weekend launches Cost: ~$199-$299 | Stack: Next.js, MongoDB or Supabase, Stripe or Lemon Squeezy

ShipFast is the most famous name in this space, and it's honestly marketed. Its goal is shipping in a weekend. It's quick to set up, lightweight, and backed by a large community of indie hackers.

The downside is depth. ShipFast optimizes for time to revenue, not maintainability. There's no multi-tenancy, no RBAC, no layered architecture, which is fine if all you need is a landing page with a checkout. Once the product becomes more complex it gets problematic.

Best for: Indie hackers validating ideas quickly.

Skip if: You're building B2B or anything with teams and roles.

MakerKit - Best for multi-tenant B2B Cost: ~$299+ | Stack: Next.js, Supabase, React 19, TypeScript, Tailwind

MakerKit is one of the most comprehensive kits for a team-based SaaS application. It comes with organization support, invitation handling, tenant billing, and role management right off the bat. Documentation is very strong and it's actively maintained.

The cost is complexity. MakerKit packs quite a bit of abstraction and has a tight coupling with Supabase. If Supabase is what you're planning to use, that's great. Otherwise, migrating from it could be a challenge.

Best for: B2B SaaS with teams and workspaces from day one.

ixartz SaaS Boilerplate - Best free open source option Cost: Free (Pro/Max tiers) | Stack: Next.js, Clerk, Drizzle ORM, Shadcn UI

The most starred SaaS boilerplate on GitHub for a good reason. Comes with auth via Clerk, multi-tenancy, roles and permissions, i18n, testing suite with Vitest and Playwright, and dependencies getting updates once a month.

There are two things to consider. First, Clerk is a hosted authentication service that charges per usage. So, if you're looking for a "free boilerplate", you shouldn't expect it to be cost-free. Second, the most useful features (Stripe integration, self-hosted auth) are tucked behind Pro and Max tiers.

Best for: Developers who want to read excellent code and aren't bothered by Clerk's pricing.

Supastarter - Best for the Supabase ecosystem Cost: ~$349+ | Stack: Next.js (also Nuxt/SvelteKit), Supabase, TypeScript

Supastarter comes with auth, billing, i18n, and AI-powered features across multiple frameworks. Quality is high, and updates are frequent. Pricing is at the top of the market, and like with MakerKit, it presumes you're committed to Supabase.

Best for: Teams who already picked Supabase and want polish and support.

Vercel saas-starter Best Minimal Official Starter Price: Free | Stack: Next.js, Postgres, Drizzle, Stripe

Vercel's own open source starter. It's minimal by design: auth, a Stripe subscription flow, and a dashboard skeleton. Think of it as a reference implementation, not a product foundation. You'll build most of your SaaS yourself, but you'll build it on patterns the Next.js team endorses.

Best for: Learning current Next.js patterns, or teams that want to own every line.

Open SaaS (Wasp) - Best free full-stack alternative Cost: Free | Stack: React, Node.js, Wasp, Prisma, Stripe

Free full-stack solution including auth, Stripe, admin dashboard, email and some AI examples. The drawback is Wasp itself: a full-stack framework with a custom config format. It eliminates boilerplate but adds a framework dependency most React developers aren't familiar with.

Best for: Build zero-budget project with the willingness to use Wasp.

Gravity - Best Non-Next.js Option Cost: ~$400+ | Stack: Node.js + Express, React (separate client)

Not every React SaaS is built with Next.js. Gravity implements classic separation of concerns: Express API server, React frontend with billing, auth, organizations, and mobile app templates.

It's mature and battle-tested, with years of updates behind it.

Best for: Teams who want a separated API and client, or need a React Native mobile app companion.

T3 Stack - Best Scaffolding for Full Control Cost: Free | Stack: Next.js, tRPC, Prisma or Drizzle, Tailwind, NextAuth

T3 is not a boilerplate itself. It's a type-safe scaffolding that's widely used among React developers for building various types of software. People create their SaaS applications based on it. You get a fully-typed backend-to-front end communication and nothing else: no billing, no multi-tenancy, no RBAC. You implement that yourself.

Best for: Developers who need full control and don't mind implementing the SaaS part themselves.

How to Choose the Right One
There are three questions that clear everything up:

Are you validating or building your SaaS?

Validating the idea? Speed wins. ShipFast or even free boilerplate will suffice.

Building something you're going to maintain? Architectural soundness wins. Then this article shows why Kostra and MakerKit are worth their price.

Do you need teams and roles?

B2B implies multi-tenancy and RBAC right away. Very few options here can deliver that out-of-the-box. Implementing it retroactively is one of the hardest things to do in a SaaS development process.

How locked-in you're willing to be?

Clerk, Supabase, and Wasp are all great tools, but they're also dependencies with their own pricing models and roadmaps. Choosing boilerplates that work with standard building blocks (Prisma, PostgreSQL, JWT, S3) leaves more options open.

The Real Cost
$150-$350 boilerplate seems pricey compared to a bunch of free options. Not really. Wiring auth, Stripe webhooks, email, storage, RBAC and setting up deployment will take 80-150 hours of work if you do it properly. At any reasonable rate, a paid boilerplate pays off in the first afternoon.

It's not the initial price that's the real cost. It's picking a boilerplate that has poor architecture and making that decision pay off in month 6 when every addition is fighting the codebase.

Frequently Asked Questions
What's the difference between React SaaS boilerplate and Next.js SaaS boilerplate in 2026?
Pretty much none. Virtually all React SaaS boilerplates nowadays use Next.js as a standard framework for production React applications. These two terms are interchangeable.

Are free and open source SaaS boilerplates good enough?
For learning and side projects yes. But for products with paying customers, make sure that maintenance is regular and paid features are not needed. Plenty of "free" boilerplates charge for payment processing or auth, or require a hosted service with usage pricing.

How much time does a SaaS boilerplate save?
Three to six weeks of groundwork: auth, billing, email, storage, RBAC and deployment. The more solid the architecture, the more time it saves during maintenance.

Which SaaS boilerplate is the best for solo founders?
If you're just validating the idea, ShipFast. If you're building the actual SaaS, Kostra is the boilerplate with the most solid architecture available for the lowest price.

Conclusion
The best React SaaS boilerplate depends on what you're optimizing for. Speed to launch favors ShipFast. Team-heavy B2B favors MakerKit. Zero budget favors ixartz or Open SaaS.

If you want the strongest balance of price, architecture, and completeness, Kostra delivers a production-ready Next.js foundation for $150 one-time. Auth, Stripe, RBAC, storage, email, and an admin dashboard, built on a layered architecture you won't outgrow. See how it stacks up against ten other Next.js boilerplates.

Next.js SaaS Boilerplate: Best Options for 2026

Prince — Thu, 09 Jul 2026 10:28:20 +0000

Developing a SaaS product from scratch takes weeks of setting up, even before writing one line of the product's functionality. A Next.js SaaS boilerplate will save this time by providing you with the basics (authentication, billing, and dashboard integration) so that you can focus on writing the actual paying part of your product on the first day.

In this guide, we will compare all major options available in 2026, list the criteria to distinguish a quality starter from a bad one, and show you how to choose the right one for your specific case. We will also consider what the decision to use the starter looks like six months after launching your app instead of right at the beginning, because this is when the real cost of a poor choice becomes apparent.

Quick summary, if you are short on time: if you need to have multi-tenancy and billing working properly on day one and the value of your time is higher than the price of a license fee, a paid option such as Kostra would be the faster path. If you are validating your idea, feel comfortable building auth and billing by yourself, and have no budget, an open-source option such as T3 Stack or the official Vercel SaaS Starter would be the better choice. The rest of this guide explains why this way.

What is a Boilerplate Code (Quickly)
Boilerplate code is reusable code that you put into every new project instead of coding it from scratch. It is the repetitive setup code that every application needs but is not related to the product-specific features at all.

SaaS boilerplate is the same idea, but applied to a product. Not only configuration and structure but a ready-to-use starter template with the basics (auth, billing, multi-tenancy, and dashboard) implemented. And the main thing to add is the product itself, not the whole infrastructure around it.

For the full breakdown of what boilerplate code is, as well as for the difference between boilerplate, a framework, and a library, read our guide on what boilerplate code is and what a SaaS boilerplate actually includes, respectively.

Why Next.js for Your SaaS Starter Kit
Routing, API endpoints, and server rendering in one place is why Next.js became the default choice for building SaaS products based on React. In combination with the SaaS starter kit, you have a ready-to-use full-stack foundation instead of a barebones project.

Speed. Auth, billing, and emails are set up before writing your first feature. You can ship on the first week instead of setting everything up.

Modern tech stack. App Router, TypeScript, Tailwind CSS, and Prisma (or Drizzle) are the standard tools used in nearly all serious starters in 2026. All of those are not optional anymore.

Deployable. Most options provide a starter kit that is ready to deploy on Vercel with one click, templates for environment variables, and ready-to-go API routes.

Large community. Next.js has one of the largest developer communities among frameworks. Any bug is quickly fixed, and it is much easier to find a contractor/hire familiar with the stack than one familiar with the niche framework.

Built to scale. A boilerplate created in the right way does not lock you inside of it. And if you are planning for the future, it is good to understand how a Next.js SaaS actually scales from starter to production before you commit to one stack over another.

What to Check Before Picking One

Not every starter that is called a "SaaS boilerplate" has all the required functionality. Some are landing pages with the login form included. Here is what to check before making a choice.

Authentication
Your boilerplate should support real authentication, not a demo login page. At least, the following things are needed:

Email and password login

OAuth (Google, GitHub, or both)

Magic link login

Protected routes and proper session management on the server, not just the client

Skipping this and doing auth manually is one of the slowest and error-prone parts of any SaaS development. Also, auth bugs are the security bugs that should not be skipped under any circumstances. For the detailed description of what proper SaaS auth in Next.js should look like, read our guide on how to build authentication in a SaaS.

Billing
Billing is the most complex part of any SaaS application. And poor boilerplate shows its flaws here the quickest. A SaaS starter should include:

Stripe integration that goes beyond a checkout button

Subscription plans and tiers, including upgrades and downgrades

A customer billing portal so users can manage their own subscription

Webhook handling for payment events like failed charges, cancellations, and renewals

Most free starters provide a simple Stripe checkout example but completely skip the webhook handler. This means that the state of subscription could fall out of sync with what Stripe charges users. And if there is some missing or poorly-written billing logic, you would spend weeks to implement it correctly. For more details on what is needed for a production-level billing setup, read on Stripe billing integration for Next.js SaaS and our broader Stripe SaaS billing guide.

Multi-Tenancy
Multi-tenant SaaS boilerplate allows one codebase for serving many different customers, each of whom has isolated data.

There are a few common patterns for this:

Shared database, tenant ID column. Simplest to build, cheapest to run, requires careful query discipline to avoid data leaks between tenants.

Schema-per-tenant. Better isolation, more operational overhead as your tenant count grows.

Database-per-tenant. Strongest isolation, usually reserved for enterprise contracts with strict compliance needs.

Once you sell to companies or teams, implementing multi-tenancy would mean rebuilding your data layer, your auth flow, and billing logic at the same time. Choose this option beforehand if there is any chance you would need this functionality. For more information on architectural tradeoffs, see our guide on Next.js multi-tenant architecture patterns.

TypeScript
TypeScript prevents bugs on the deployment and makes a codebase more maintainable because it is easier to hand over a project written in TypeScript to another developer than to teach him/her the codebase written in vanilla JS. All serious starters use TypeScript as a default language in 2026, so the boilerplate that uses JS instead of TS could be considered inactive. For some tips on how to use TypeScript in a SaaS codebase, see our TypeScript best practices for Next.js SaaS apps.

Database and Email
Prisma with PostgreSQL is the most common default database among serious starters, although Drizzle is becoming popular too for the teams preferring an SQL-like ORM. As for the emails, Resend, Postmark, or SendGrid should be supported because all SaaS applications send transactional emails (welcome message, password reset, billing receipt, invoices, etc.). Leaving it aside would mean wiring up an email provider by yourself.

Performance
The starter that loads slowly at the very beginning would become even more sluggish with time. Make sure that the starter includes proper defaults for image optimisation, caching, and bundle size. Our guide on Next.js performance optimisation for SaaS apps covers what good defaults actually look like.

Security and Route Protection
A surprisingly large amount of starters protect routes only at the client-side level, which means that it is possible for a determined user to bypass the check completely by calling an API directly. The proper route protection should be done at the server side, not in the client-side component.

Also, it is worth checking if passwords are hashed with a modern algorithm, if there is any login attempts' rate limiting, and if the session management does not allow session fixation attacks. None of this is a complex security task, but this is exactly the kind of thing that is often left aside in a starter created just to make a good demo video.

API Rate Limiting
Once your SaaS has real users, unprotected API routes become a liability really fast because of misbehaving clients and possible abuses. And the starter built for production should provide some starting point for rate limiting rather than leaving all of the endpoints unprotected. If your starter does not include this, you can read our guide on API rate limiting for Next.js SaaS apps walks through how to add it properly.

Comparison Table

Frequently, the pricing, feature set and maintenance status change in this area. Be sure to verify all the details directly on the website/repository of each particular product you consider before making a decision, and do not rely solely on any comparison article, including this one.

The Options, Compared Fairly
Kostra
Paid Next.js boilerplate with authentication, Stripe billing, multi-tenancy, and dashboard that comes with pre-set connections. Designed specifically for the startup founders who are interested in starting with product features development on day one by skipping the setup phase completely. The trade-off here is pretty obvious - you invest upfront money in order to save time, but you are losing community flexibility and the zero upfront cost of open source projects.

You should go with Kostra if you already know that you definitely need multi-tenancy, you do not want to wire billing webhooks yourself, and your time is worth more than the license. Otherwise, Kostra will make less sense for you, especially if you are in the validation phase of your idea and are not sure if you need any of these features. For a detailed feature-by-feature comparison with an open-source alternative, see T3 Stack vs. Kostra.

T3 Stack
Popular open-source SaaS boilerplate consisting of Next.js, tRPC, Prisma, Tailwind, and NextAuth. One of the best TypeScript stacks of all the starters listed on this comparison, as it ensures end-to-end type safety from your database to the frontend of your project and has very strong community backing.

The thing is that T3 Stack does not provide you with billing and multi-tenancy capabilities. So, you implement these yourself and depending on your experience with Stripe webhook and multi-tenancy design, it may take you from a few days to a few weeks. It may sound discouraging for some developers, but for others, T3 Stack is the perfect option.

Vercel SaaS Starter
Official Vercel starter package. It is free, simple and minimalistic boilerplate with a basic Stripe billing implemented. Good choice for solo projects and anyone who wants to implement the proper architectural patterns of Next.js SaaS.

It does not provide multi-tenancy, role-based permissions and complex billing implementation that paid starters and more feature-complete open source projects offer. Consider it not as a ready-to-use solution, but rather as a clean documentation example you can start from.

Node.js SaaS Boilerplate (Backend-First)
Good choice for projects where you need a separate backend on Express or Fastify along with a Next.js frontend instead of using Next.js API routes for everything. In some situations, such a backend-first approach gives you more control over the back-end architecture of your project, especially if you plan to develop a service layer, background jobs processing or even microservices in the future.

However, you have to put more effort into the initial setup compared to other options and the quality of various open-source Node.js SaaS boilerplates differs dramatically. So, be careful and check the history of commits and issues on GitHub very carefully before choosing any generic option from this category.

How Much Time Does a Boilerplate Actually Save?
This is the question that defines whether it is really profitable for you to pay for a boilerplate or not. It is always good to be clear about the benefits of "saves you time".

Proper implementation of auth (including OAuth, session management and password reset flows) takes about three to five days for an experienced developer. Implementation of billing with Stripe (subscription tiers, customer portal, and properly implemented webhook handler) takes an additional week at least and even longer if you are implementing it for the first time and need to understand the Stripe events mechanism. If you build multi-tenancy from the beginning, it will add an additional few days to a week, depending on the isolation pattern you choose.

So, the careful implementation of auth, billing, and multi-tenancy from scratch takes you about two to four weeks before you can start with product features development. Boilerplate that implements all these things correctly saves you a whole this time, and whether it is worth it or not depends only on your own hourly rate and your runway. But, as a rule, it is more beneficial to pay for the boilerplate in case of funded/revenue generating teams.

Total Cost of Ownership: Free vs. Paid
The license fee is not the only factor defining the total cost of the solution. Free boilerplate does not have a license fee, but it transfers the cost into development time, maintenance and risks.

Setup time. Free boilerplates require you to fill the gaps by yourself, which is an additional time investment.

Maintenance burden. Open source projects require continuous maintainers' interest. In case of paid boilerplates, there is always a commercial interest to update the boilerplate with the Next.js versions in a timely. In the case of free projects, updates will happen when the maintainer finds enough time for them.

Documentation quality. As a rule, paid boilerplates provide the documentation describing why particular decisions were made by the author, not only how to set up the boilerplate. It becomes crucial in case of debugging problems which were created by someone else six months ago, and there are no comments explaining why a particular architectural decision was made.

Support. When something goes wrong in the middle of the night in production, paid boilerplate with support channel or community Discord will give you the answer faster than searching GitHub issues on a free repository with a small maintainer base.

But it does not mean that free boilerplates are bad options for you. In the early stage of validation, it is better to choose a free boilerplate with a smaller feature set, since you are not sure yet if you need all these complex features. Things will be different if you already have paying customers and your downtime has financial consequences.

How to Choose
Go through these five questions before choosing any starter.

Do you need multi-tenancy? If the answer is yes or probably you will need it, do not choose the boilerplate which requires you to implement multi-tenancy later. Addition of tenant isolation to existing data model is one of the most painful refactorings in SaaS development.

What does your team already know? Boilerplate developed with stack that your team never uses before increases the learning curve on top of the saved setup time. Match the stack to the actual strengths of your team, not to the most popular one.

How fast do you need to ship? Paid boilerplates save calendar time but cost you license fee. Open source boilerplates save money but cost you engineering hours. Choose the constraint that you are actually struggling with.

Are you deploying to Vercel? Make sure that the starter was developed with it in mind (edge runtime compatibility and environment variables convention) instead of assuming that any Next.js project will deploy with no adjustments.

Is it still maintained? Before choosing the open source boilerplate, check the GitHub commit history. Repository which does not have any commits during last few months is risky when Next.js, React and your auth provider will ship breaking changes.

If you want the detailed overview of the decision process, including the description of how to balance all these aspects in order to choose the starter that suits your needs, see our full guide on how to choose the right Next.js boilerplate for your SaaS.

Common Mistakes
Adding multi-tenancy after launch. Usually, it requires a partial rebuild of your data model, auth flow and billing logic. If there is any possibility that you will be selling to teams or companies, you should implement the multi-tenancy from day one.

Choosing the dead project. No updates mean no security updates and a lack of maintainer's interest in case your dependency breaks. Always check the recent activity of the project, not only the number of stars, before using the free boilerplate.

Picking a bloated starter. Some boilerplates come with a lot of features that you will never use in your project: internationalisation you will not use, a role system with five permission tiers for your two-man team and an admin panel for features you have not yet implemented. Instead of working with real features, you spend the time stripping the unnecessary things. Choose boilerplate according to your scope, not the most feature-complete one.

Skipping TypeScript. It is much faster on the initial stage of development, but costs you much more in the debugging process once your project grows bigger and has more than a few files, especially in case a second developer joins your project.

Underestimating billing complexity. Many founders think that "Stripe integration" equals to the presence of a checkout button on your page. Actually, the main thing in Stripe billing is handling the webhooks: synchronisation of your database with subscription upgrades/downgrades, failed payments and cancellations. Boilerplate that skips this step will give you a gap, which usually appears in case of a real customer's card problem.

What Happens Six Months After Launch
Comparison of SaaS boilerplates ends with the moment of setup in many cases. The more important question is what your codebase will look like in six months after launch, after you have implemented some features that the starter does not have.

Dependency drift. Next.js, your auth library and Stripe's SDK are updated separately. A starter that was up-to-date at the time of your launch will become outdated very soon if nobody maintains it. And this is the main reason why it is always good to check the GitHub history of commits before choosing the starter, not only when you will clone the repository, but in order to make sure that it will stay safe to use a year later.

Schema migrations. Your data model will change: additional columns, tables for unimplemented features, tenant-level settings. Starting with a clear and documented migration approach will help you in this process; starting with a messy schema or without documentation will turn every change into an investigation.

Onboarding of the second developer. The first developer who started working on the starter understands all the decisions that were made in the starter because he/she made most of these decisions himself/herself while implementing the starter. The second developer does not have this advantage. And in this case, documentation becomes a crucial thing instead of nice to have: it becomes the difference between a smooth onboarding process and week of confusion in Slack. And it becomes one of the biggest differences between free and paid starters: paid starters usually contain documentation with architectural reasons, and free ones have only setup documentation.

Scaling beyond the starter's assumptions. Every starter has assumptions about your tenant model, billing, traffic, etc. It will work perfectly for the first thousand users, and sometimes it will start to struggle after that. It is always good to know which assumptions your chosen starter has and how hard it will be to change them later. See our guide on scaling a Next.js SaaS from starter to production, which walks through exactly where these strains tend to show up first.

Final Thoughts
Right Next.js SaaS boilerplate depends on your timeline, the stack of your team and the need for multi-tenancy from the beginning. Open-source starters like T3 and Vercel starter boilerplate give you flexibility and zero upfront cost, but require more setup time and continuous maintenance from your side. Paid starters like Kostra save you setup time and reduce maintenance risk, but have a higher upfront cost and less flexibility in changing architecture.

It is always good to make your own choice instead of looking for the universally correct answer. A solo founder who validates an early idea has different needs from a funded team that builds for an enterprise contract.

Frequently Asked Questions
Is a Next.js SaaS boilerplate worth it for a solo founder?
It all depends on what do you know how to implement in two days. If you can correctly build auth and billing with Stripe, a free boilerplate like T3 or Vercel SaaS Starter may be enough for you, because you just know how to extend the project. However, if this is your first experience of creating a SaaS or you want to validate an idea in a week, a paid boilerplate with billing and multi-tenancy implementation always saves you time.

Can I switch boilerplates after I have already started building?
Yes, but it will become more difficult the further you move along in your project. Changing the auth provider when you already have real user accounts requires the plan of moving from one set of credentials to another. Changing the billing system when you already have paying customers requires careful migration of active subscriptions so that nobody's billing cycle is broken. It is easier to spend several more days choosing a boilerplate from the very beginning than to migrate after six months of development.

Does a multi-tenant SaaS boilerplate cost more to run than a single-tenant one?
Not necessarily. A boilerplate with a shared database and a tenant-ID model of multi-tenancy costs approximately the same as a single-tenant SaaS project, because you don't duplicate your infrastructure for each tenant. Additional costs appear in case of more isolated approaches like schema-per-tenant or database-per-tenant. They provide higher security of data but at higher costs of operation, justified by the necessity of using them when you get enterprise customers.

Do I need TypeScript for a Next.js SaaS, or is JavaScript fine?
If you use JavaScript, your project will work properly. But when your team grows larger or you create a SaaS with a complex data model where typos in property names should be detected beforehand, TypeScript will save your time in debugging. In the case of SaaS that you are going to maintain for several years, the initial time spent on learning it is insignificant compared to the time during debugging.

What is the real difference between a "boilerplate" and a "starter kit"?
In practice, there is no big difference between them, and both terms are interchangeable for almost everyone in the industry, even in this guide. Some people mean a bit more minimal foundation in case of "boilerplate" and something closer to a ready solution with UI in case of "starter kit". There is no exact industry standard dividing the two terms, so when choosing your boilerplate, look at its features instead of the name.

The Complete Guide to Choosing a SaaS Starter Kit

Prince — Thu, 09 Jul 2026 09:59:30 +0000

Almost all guides on choosing the best SaaS kit answers a question that's not relevant to the problem at hand. They suggest which kit is the most popular, which has the most stars, or which one the author liked after reviewing it. But none of this is going to help you choose the right SaaS kit for your project.

It's not about "which is the best SaaS kit?" It's more like "what does my project require, and which kit meets the requirements with the lowest overhead?" This guide provides you with a decision-making framework. Go through it sequentially, and in the end, you'll have a definite answer that is relevant to your case.

The Four Questions That Determine Your Choice
All SaaS kit decisions are driven by four variables. Star counts, feature lists, landing page claims, etc. become irrelevant until you answer them.

What stage is your product at? The kit that is suitable for validation purposes might be useless for growth stage. And, vice versa, the kit designed for production B2B companies is too complex for an unvalidated product.
What does your technology stack require? Auth provider, database, ORM, billing, email, file storage, deployment target – each additional requirement that a certain SaaS kit doesn't meet is the additional work that has to be done after you clone the repository.
What is the size and experience of your team? An individual first-timer and a 5 person experienced dev team have completely different requirements from the starting point.
What are your infrastructure limitations? Vercel-only, Docker-only, AWS ecosystem, data residency requirements, enterprise compliance and such – all these questions limit the number of choices very quickly.

Answer these questions before even taking a look at kits themselves.

Question 1: What Stage Is Your Product At?
Pre-validation (0 users, unconfirmed demand)
At this stage, your main concern is speed of validation. You need to launch the product and get to the customers to see if they would like to buy it. Quality of architecture is a secondary thing.

What this means for your kit choice:

Choose the simplest kit available. Usually, this is the minimal free options: official Vercel starter and ixartz SaaS Boilerplate.

Over-featured kits should be avoided at this stage. The kit with 30 pre-built features requires several days to understand it fully. Better spend time on speaking with future customers.

The right question: Can I get auth, billing, and a dashboard working today?

MVP stage (building toward first paying customer)
You have your product idea, and now you're building the infrastructure. Speed matters. The quality of architecture is less important than delivering.

What this means for your kit choice:

A minimal free starter with multi-tenancy (if your product requires it) or just a minimal free starter (in case it doesn't). The ixartz SaaS Boilerplate covers almost all needs at this stage without charge. The official Vercel starter is more clean if you like to start with a minimum and gradually add features.

Premium kits become justified in cost at this stage if: you've shipped SaaS before and know what you're doing, your requirements include infrastructure not covered by free options, or you value the quality of documentation explaining decisions made and not only setup procedures.

The right question: What's the minimum kit that covers my specific requirements?

Post-validation (paying customers, rebuilding for growth)
Your MVP was successful, and you have some revenue. You're rebuilding it with the proper architecture prior to scaling the team or the product.

What this means for your kit choice:

Quality of architecture starts mattering now. Layered service patterns, repository-pattern DB access and decisions of multi-tenancy data models you make at this stage will define how quickly you could go in the next two years.

Free starters, developed and maintained by a single developer, start becoming risky at this stage. Maintenance dependence is real when your business relies on up-to-date and secure infrastructure layer.

The right question: Which kit has the architecture and maintenance quality to carry a growing product?

Growth stage (team of 3+, scaling users)
You have a team, real revenue and growing complexity. This is the stage when the kit becomes not only a starting point but the foundation that multiple developers build upon.

What this means for your kit choice:

Most likely, you won't choose a new SaaS kit at this stage – you live with the chosen one already. However, if you feel that it starts causing problems (developers are constantly fighting the architecture, technical debt is growing faster than new features), then this is the moment when migration becomes justified.

Paid kits with good architectural patterns, maintenance and documentation justify their cost at this stage. Alternative – pay in developer hours.

The right question: Is our current foundation accelerating or constraining our development velocity?

Question 2: What Does Your Stack Require?
Map your requirements before looking at any kit. For each item, mark Required, Preferred, or Don't Care.

How this maps to kits:

Self-hosted auth: Kostra (custom JWT), nextjs/saas-starter (Auth.js)

Hosted auth: ixartz SaaS Boilerplate (Clerk), Supastarter (Supabase Auth)

SAML/SSO: BoxyHQ SaaS Starter Kit

How this maps to kits:

Question 3: What Is Your Team Size and Experience?
Solo founder, first SaaS
Primary need: Speed and clarity. You need to know everything about each part of the codebase to be able to debug it at 11 pm before launching. Documentation quality is more important than architectural elegance.

What to look for: Good README with the description of the setup process. Small enough codebase that can be reviewed in a couple of hours. Active community for questions.

Kits that fit: Nextbase ($99) for documentation quality, ixartz SaaS Boilerplate (free) for feature completeness, nextjs/saas-starter for clarity.

What to avoid: Over-engineered kits that would take days to get acquainted with. Kits with poor documentation. Kits that were not updated in the past six months.

Solo founder, experienced (shipped SaaS before)
Primary need: Architectural quality and infrastructure flexibility. You know what goes wrong when scaling up and want to avoid problems from the very beginning.

What to look for: Layered architecture, multi-tenancy in the data model, configurable infrastructure, active maintenance.

Kits that fit: Kostra ($150) for architecture and infrastructure flexibility. Supastarter for advanced multi-tenancy in the Supabase ecosystem.

What to avoid: Minimal starters that require much extension work. Kits whose architecture does not fit your patterns learned from previous experience.

Small team (2-4 developers)
Primary need: Consistent patterns that can be followed by everybody in the team. Faster code review as a result of consistent architecture.

What to look for: Opinionated folder structure, separation of concerns, TypeScript everywhere, documented conventions.

Kits that fit: Kostra (Atomic Design + repository pattern + service layer = predictable patterns for team development). ixartz SaaS Boilerplate (Bulletproof React patterns = clear conventions).

What to avoid: Kits with inconsistent conventions. Kits with database queries inside both API routes and services files.

Larger team (5+)
Primary need: Scalable architecture in accordance with the complexity of the codebase. Onboarding documentation. Testing infrastructure.

What to look for: Layered service architecture, comprehensive test suite, CI/CD, error monitoring, logging.

Kits that fit: ixartz SaaS Boilerplate for testing (Vitest + Playwright + CI/CD). Kostra for layered architecture. Blazity/next-enterprise for observability.

What to avoid: Any kit without tests. Any kit without documented architectural decisions.

Question 4: What Are Your Infrastructure Constraints?
These are the constraints that override everything else. In case if you have one of these, it immediately narrows down available options.

"We need Docker or self-hosted deployment"
Eliminates: all Vercel-only kits. Keeps: Kostra (Docker included), any kit that you host yourself.

"User data must stay in our database"
Clerk-based kits (Clerk stores user data on their servers), Supabase Auth-based kits (auth data in Supabase).
Keeps: Kostra (custom JWT), nextjs/saas-starter (Auth.js with Prisma adapter).

"We need SAML SSO for enterprise customers"
Eliminates: all standard kits without SAML integration. Keeps: BoxyHQ SaaS Starter Kit (SAML Jackson built in), kits where you add Clerk's enterprise tier.

"We need data residency in a specific region"
Eliminates: all kits with hosted services which do not provide region choice option (some configurations of Clerk and Supabase). Keeps: Kits with self-hosted auth and database provider that supports your region.

"We're already on AWS"
Eliminates: nothing, but favors kits that support AWS SES and S3. Keeps: Kostra (AWS SES + S3 built in).

"Our billing needs are complex (usage-based, seat-based, metered)"
Eliminates: kits that have basic implementation of Stripe subscription checkout. Keeps: any kit where you can integrate billing via custom Stripe integration, or Kostra where the billing layer is well-separated.

The Decision Matrix
Run your requirements through this. Your final answer is where your constraints intersect.

*Verify current availability before purchasing.

Good fit for you if: Supabase is your database of choice and multi-tenancy complexity is crucial for your product.

Nextbase ($99 Essential, $299 Pro, $399 Ultimate)
Designed for: First-time SaaS builders who need top-notch documentation and full feature set.

Architecture: Supabase-native, all-inclusive feature set (blog, feedback, roadmap, changelog, entity builder).

Actual strength: Best documentation on the market. Most pre-built product features. Lowest price among complete kits.

Good fit for you if: This is your first SaaS project and documentation quality matters much for the setup process.

Here are the patterns that keep coming back to cause regret according to the community conversations.

Picking a kit by GitHub star count
GitHub stars measure popularity in the past. They say nothing about the maintainability, quality, and currency of the code - does the kit use Next.js 16, Tailwind v4, and the December 2025 security patches? The kit with 5k stars and no activity in 14 months is inferior to the 400-star one with weekly commits.

Check last commit date before checking star count.

Going for the kit with most features
Pre-built features sound like a good thing to have, but in practice every feature you did not write yourself means one more feature to read through, understand, and maybe even strip out before using the kit as a base for your product. Kit with 30 unnecessary features is going to take you two days of stripping out.

Choose a kit that fits your needs, not the one with maximum number of pre-built features.

Purchasing a paid kit without validating the idea first
$300 spent on a kit is a cost when the product hasn't been validated yet. There are free kits (ixartz, Vercel official) which are fully capable of serving as a base for the MVP. Buy paid kits when there's a validated product worth investing in.

Picking a kit based on a tutorial
YouTube is filled with tutorials about building applications on various kits. Usually the kit with most tutorials is the easiest one to create tutorials about. But it is not necessarily the kit with the best match of your requirements.

Neglecting the auth layer provider considerations
Many developers face this exact problem: buying a kit that uses Clerk for authentication, building a product on it, then finding out in production that Clerk's per-MAU pricing is actually a meaningful cost or that one of the customers requires self-hosted auth because of data residency regulations.

Know your authentication requirements before choosing a kit. Refactoring auth library will be a painful process once the app is built.

How to Validate Your Choice Before You Commit
Ten minutes of validation before choosing a kit save days of regret.

Check #1: Last commit date
GitHub repository -> look at the commit date of the last commit. More than three months old -> cautious. More than six months -> probably not current enough for the ecosystem.

Check #2: Next.js version
Open package.json -> search for "next" in dependencies. Latest version -> 16.x. Version below 15.x -> significantly outdated.

Check #3: Get it running locally
npx degit username/repo test-project

cd test-project

npm install

cp .env.example .env.local

Fill in minimal number of env variables

npm run dev

If you cannot get it running in less than half an hour following just the README, the documentation is not adequate for your needs.

Check #4: Try the core flow
Sign up. Login. Upgrade to a paid plan using Stripe test card 4242 4242 4242 4242. Check if the subscription status is properly updated in the database. Log out and cancel the subscription. Check if the access is revoked.

If something goes wrong at any of these steps or behaves improperly, you have found the production bug before writing any product code. This is valuable information.

Check #5: Read the schema
Open prisma/schema.prisma or the equivalent file. If you need multi-tenant support, check if there are appropriate foreign keys in the domain models (organizationId). If they are userId -> what is being sold as "multi-tenant" is actually user-scoped data.

Check #6: Dependencies audit
npm audit

No vulnerabilities -> good. High or critical vulnerabilities that have been open for months -> the maintainer doesn't care about the security of the codebase.

If the kit passed all six checks, you have a well-maintained and production-ready base.

Which SaaS Kit should I use as a solo founder in 2026?
That depends on two factors: if you have experience building SaaS products before, and if multi-tenancy matters to your project. For a solo founder who has never built SaaS products before: Nextbase ($99) for documentation quality or ixartz/SaaS-Boilerplate (free) for feature completeness. For a seasoned solo developer building a B2B SaaS product: Kostra ($150) for architectural quality and infrastructure flexibility.

Do I need a free or paid SaaS Kit?
Free SaaS Kits are the way to go before product validation. Paid kits earn their cost after validation, when architecture quality and maintenance reliability will influence your development velocity and business continuity. Developers who regret spending money on paid kits did so before validation. Developers who regret sticking to free kits are the ones who stuck with them until architecture deficiencies began eating up engineering time.

How do I know if a SaaS kit is actively maintained?
Look at the last commit date on GitHub (it should be within the past three months for an actively maintained project). Look at the open vs closed issue ratio. Look at whether there are responses to the issues from the maintainer. Look at whether the next version listed in package.json is the latest. Look at whether Tailwind v4 CSS-first config (@import "tailwindcss") is used instead of the old JS config file.

What is the difference between a SaaS template and a SaaS kit?
A SaaS Kit (also called a boilerplate or starter kit) is a functioning application: authentication works, payments are processed, database schema is ready. It's something you clone, replace env variables, and voila – you have a product. A SaaS Template is mostly UI-related: page templates, layouts, components without the underlying infrastructure. When developers refer to SaaS Templates, they usually mean Kits. Make sure authentication and Stripe integration actually work before assuming that you have a kit.

Which SaaS kit has the best multi-tenancy?
Based on community mentions and active maintenance

Which SaaS kit should I use if I need Docker support?
Kostra is currently the only known Next.js SaaS kit with Docker deployment and Docker Compose included out of the box. Other kits can be containerized through extra effort, but Kostra is the only kit for which Docker deployment is an inherent feature of the product.

Which SaaS Kit works best for B2B product?
Building B2B SaaS requires certain considerations that make the list much shorter: multi-tenancy in the data model, not in the application; role-based access control per organization; billing per organization; and sometimes Single Sign-On via SAML protocol for enterprise customers. Kostra for the architectural backbone. BoxyHQ for SAML. Supastarter for advanced multi-tenancy with Supabase. MakerKit for sophisticated role-based access control. The worst choice for B2B is any kit that doesn't treat organizations as a first-class citizen in the schema.

Bulletproof Next.js SaaS Starter Kit Review

Prince — Thu, 09 Jul 2026 09:45:14 +0000

There have been numerous queries about "bulletproof nextjs saas", "nextjs saas kit bulletproof", "best bulletproof next.js template", "saas starter kit by bulletproof next js github", etc.

None of those refers to any officially released product. Those phrases were chosen to describe ixartz SaaS Boilerplate, which is a free, open-source Next.js SaaS starter kit created by Remi Weng (ixartz) and based on the Bulletproof React architecture guide adjusted for Next.js and SaaS functionality built on top of it. In the following review, we will explain what the ixartz boilerplate is doing well, what can be improved and how it compares to Kostra – our paid, production-ready solution.

Disclosure: This review is written by the Kostra team. We analysed the ixartz boilerplate based on its publicly available GitHub repository and documentation.

What Is the Bulletproof Next.js SaaS Boilerplate?
The name comes from the "Bulletproof React" architecture guide that suggests certain practices of building React apps: a feature-based folder structure, separation of concerns and a set of conventions to keep a codebase clean and easy to maintain. The ixartz boilerplate is an implementation of these concepts for Next.js with all SaaS-related functionality built on top.

Whatever you decide to call it, Next.js SaaS boilerplate, a SaaS starter kit, boilerplate code, it is the same repository. It is completely free and open source (MIT license).
As of 2026, it is one of the most starred free Next.js SaaS starters on GitHub with thousands of stars and frequent commits.
Despite the existence of the paid Pro version (~ $99 for life) with landing page templates and extra components, the boilerplate itself remains absolutely free.

GitHub: github.com/ixartz/SaaS-Boilerplate

Note before publishing: make sure you check the current number of stars and verify that it uses the Next.js 16 version when this review is published. Both numbers change, and it is an easy way to spot a mistake in the review for the ixartz community.

Full Feature Breakdown
Authentication (Clerk)
The first controversy of this boilerplate – authentication system. The boilerplate uses Clerk as an authentication provider.

What you get with Clerk:

Email/password, social OAuth (Google, GitHub, and 15+ providers)

Magic links

Passkeys

Multi-Factor Authentication (MFA)

User impersonation (for debugging user-specific issues)

A pre-built user management dashboard

The trade-off: since Clerk is a hosted service, you won't store your user data in your database – instead, it will go to Clerk's server. Clerk has a generous free tier, but once you start using the service over that tier, you will be charged depending on the number of monthly active users, and it may be quite expensive in case your product grows into tens of thousands of users. When you have specific data residency requirements, Clerk makes you depend on a third-party service.

This isn't a reason to skip the boilerplate – this is a reason to read the Clerk pricing page.

Multi-Tenancy and Organizations
True multi-tenancy and data scoping by organisations. User belongs to an organisation, and all data objects belong to organisations, not individual users. There are three roles for an organisation: owner, admin and member. Users can switch between the organisations they belong to.

This is what separates a real multi-tenant SaaS solution from any starter kit that has the "team support" on top of the standard user model. This is a great achievement for a free boilerplate.

What does it use: the organisation management capabilities of Clerk, which are integrated with the database. Data of organisation flow from Clerk to your database, which means that tenant data is stored partially in the Clerk infrastructure and partially in your database.

Database and ORM
Drizzle ORM is used with the support for PostgreSQL, SQLite and MySQL. Drizzle is currently a preferred ORM for Next.js projects due to its lightweight and SQL-like query syntax.

The migration process is standard: each change in a schema results in the creation of migration files that can be executed with the pnpm migrate command.
Type-safe migrations.

Stripe Billing
Integrated Stripe billing with the subscription and a pricing page. A webhook handler for the main subscription events. Based on the community feedback and our analysis, this is the best coverage compared to other free alternatives.

Should be checked before release: does it handle the customer.subscription.updated and invoice.payment_failed events? Check the switch case in src/app/api/webhooks/stripe/route.ts.

Internationalisation (i18n)
A complete i18n with Crowdin for translation support out-of-the-box. Supports multiple locales.

Our honest recommendation: most developers who are developing their first SaaS products don't need i18n from day one. This is an additional complexity for your codebase that should be removed if you don't need multiple locales at the moment.

Testing
Vitest for unit tests, Playwright for end-to-end testing, pre-configured CI/CD pipeline in GitHub Actions.

This is one of the strongest differentiators of the ixartz boilerplate against other free options. Most free boilerplates come with zero tests out of the box, while the ixartz one has meaningful testing coverage and a CI/CD pipeline configured.

Error Monitoring and Logging
Sentry integration included. Structured logging with LogTape. It is a professional-level error monitoring and logging, not plain console.logs.

Security
Integration with Arcjet for bots detection, rate limiting and attacks protection on the middleware level. This is a relatively new addition, and this feature puts the ixartz boilerplate ahead of its alternatives (whether paid or free).

Developer Tooling
ESLint, Prettier, Lefthook (instead of Husky), Commitlint, Storybook for components and CodeRabbit for AI code reviews.

Tech Stack Summary

What the Ixartz Boilerplate Does Well
Active, consistent maintenance. This is by far the best thing the boilerplate has over other free alternatives. There's someone proactive in terms of following Next.js releases and upgrading the boilerplate accordingly, updating legacy packages (e.g., Husky replaced with Lefthook, Jest with Vitest, Pino with LogTape), and shipping the updates whenever there are ecosystem changes. Proactive maintenance is rarely seen in free open source projects. This one has it.

Genuine multi-tenancy. Real organisational support with proper data scoping, not just tagging users. Roles management at the organisation level. Changing organisations and working with organisations. For a free boilerplate, this multi-tenancy implementation is production-grade.

Production tooling included. Sentry, Arcjet, structured logging, Vitest, Playwright, CI/CD. You get the production tooling configured without setting them up. Most of the free starters have none of these, or just a few of them.

Architectural patterns. The Bulletproof React patterns enforced here: feature-based folder structure, clear separation of client and server code, consistent conventions throughout. A team onboarding to this codebase can orient itself quickly because the patterns are predictable.

Where the Ixartz Boilerplate Falls Short
No email system. No email transactions are set up in the boilerplate. There's no Resend, no AWS SES, no email templates. The setup of these things has to be done manually. Plan for a day for Resend and templates configuration.

No file storage. No AWS S3, Cloudflare R2, or any other file storage solution is integrated. This is not an issue for a product that doesn't require file handling at all.

Clerk dependency and cost at scale. Clerk is awesome, but it adds to the cost of your app as you become dependent on it and have per-user pricing. Developers requiring self-hosted authentication, data residency control, or a different authorisation provider need to replace the whole auth layer, which is a non-trivial change.

No Docker support. The boilerplate is meant to be deployed via Vercel only. No Dockerfile, no Docker Compose configuration. For the teams that need containerization, self-hosting, or AWS ECS/Google Cloud Run deployment, Docker needs to be added by hand.

Feature accumulation requires stripping. The boilerplate comes packed with i18n, Storybook, Crowdin integration, and some other features that many products don't need at the very beginning. Run npm run build after stripping the unnecessary features to check broken imports.

Who the Ixartz SaaS Boilerplate Is Best For
Individual developers or small teams that build multi-tenant SaaS products and need the most feature-rich free basis they can get. A combination of active maintenance, multi-tenancy, production tooling, and the zero price tag makes this boilerplate unique.

Developers who are looking to learn about SaaS architecture through the example of how multi-tenancy, auth, and billing look in the codebase.

MVPs that need to go fast and, for now, don't have the concerns regarding the cost of Clerk's free tier.

Not recommended for teams that need Docker deployment, AWS S3/R2 file storage, AWS SES emails, or self-hosted auth out of the box. Not for products where Clerk's per-MAU cost makes a difference.

How It Compares to Kostra
Given that this review comes from the Kostra development team, here’s an unbiased comparison. (If you are comparing Kostra to the T3 Stack rather than to ixartz, read our comparison of T3 Stack vs Kostra comparison.)

Points in common between the ixartz SaaS Boilerplate and Kostra include: Multi-tenancy

RBAC
Stripe billing
TypeScript
Shadcn UI

Choose ixartz if you seek the most robust free option, find acceptable Clerk pricing terms, and have no need for Docker, file storage, or ready-made email setup.

Choose Kostra if you require the users' data in your own database, Docker deployment, AWS S3/R2 file storage, or AWS SES email. In addition, Kostra's layered architecture (Atomic Design + repository pattern + service layer) would be more suitable for a bigger team where the benefits of the service layer's separation of concerns will be noticeable.

The Honest Verdict
ixartz SaaS Boilerplate definitely deserves the title of the best free Next.js SaaS starter for 2026. Its active maintenance, true multi-tenancy, production-ready tools, and Bulletproof architectural patterns speak of real value. For a free product, that's quite impressive.

However, the drawbacks are also serious: no email integration, no file storage, no Docker support, and Clerk vendor lock-in. Not every project will suffer from these restrictions. Some will handle them without problems; some might see it as an extra reason to go paid.

If your needs align with what it offers out of the box: take it. Free, actively maintained, and will help you create a multi-tenant SaaS product much faster than anything else available in the free tier.

Need file storage, custom email setup, Docker setup, or custom authentication? Count a couple of days to integrate all these into your app and only then consider it as a fully-fledged starter.

FAQs
What is the Bulletproof Next.js SaaS starter kit?
"Bulletproof Next.js SaaS starter kit" is the community name of the ixartz SaaS Boilerplate (github.com/ixartz/SaaS-Boilerplate), a free open-source Next.js SaaS starter made by developer Remi Weng. "Bulletproof" refers to the use of the opinionated architectural patterns found in the Bulletproof React guide, adapted for Next.js. There is no official product called "Bulletproof Next.js."

Is the ixartz SaaS boilerplate really free?
Yes. The core boilerplate is free and MIT licensed. There is a paid Pro tier (~$99 lifetime) that adds some extra landing page templates and priority support. All of the features that we're discussing in this review – multi-tenancy, Clerk auth, Stripe, Drizzle ORM, testing suite, CI/CD, Sentry, Arcjet – are included in the free version.

What is Clerk and does the ixartz boilerplate require it?
Clerk is a hosted authentication service. The ixartz SaaS Boilerplate was designed with Clerk in mind. Switching to a different auth provider would require a large refactoring of the auth layer. If you know you want to go with self-hosted auth and store user data in your own database, either accept the refactoring or find a different boilerplate to start with.

Does the Bulletproof Next.js boilerplate include email?
No. Email integration is not included in the ixartz boilerplate. You will need to add it yourself (Resend, AWS SES, etc.).

Does the ixartz boilerplate support Docker?
No. The ixartz SaaS Boilerplate is designed for deployment to Vercel. There is no Dockerfile and no Docker Compose config provided.

How does the ixartz SaaS boilerplate compare to Kostra?
They are similar in the sense of both being actively maintained Next.js SaaS starters with multi-tenancy and Stripe billing. The main differences are as follows: ixartz boilerplate is free, Clerk-based auth, Drizzle ORM, and does not come with email/file storage support out-of-the-box. Kostra boilerplate costs $150 one-time, custom auth with JWT, user data in your own database, Prisma ORM, comes with preconfigured integration tests, Resend/AWS SES email integration, AWS S3/Cloudflare R2 file storage support, Docker deployment support. Choose ixartz if you want to use the free tier and Bulletproof architecture. Choose Kostra if you need infrastructure flexibility and layered production architecture.

Is the ixartz SaaS boilerplate production-ready?
Yes, with the caveat that the "production-ready" status largely depends on what kind of requirements your product has. It includes Sentry monitoring, Arcjet security, and a full test suite. The Stripe integration works well; multi-tenancy is real. For most SaaS MVPs, the ixartz boilerplate is production-ready out-of-the-box. But if you need email, file storage, Docker deployment or self-hosted auth – you will be adding all of these anyway before going to production.

What is the best SaaS template for Next.js?
There's no single best Next.js SaaS template; it depends on what you need pre-built. ixartz is the strongest free option if you're fine with Clerk's auth model. Kostra is the strongest paid option if you need self-hosted auth, file storage, and Docker out of the box. Our Top 10 Best Next.js Boilerplates roundup covers more options.

How do I build a SaaS with a Next.js template?
Build your product on top of a starter template that has auth, billing, and a database layer already built. With ixartz, Clerk takes care of the auth part, and Stripe takes care of the billing – all wired up. In the case of Kostra, everything is wired up out-of-the-box, so you can start implementing product features from day one.

Are there free SaaS templates for Next.js?
Yes. As of mid-2026, the most complete free SaaS template is ixartz SaaS Boilerplate with multi-tenancy, Stripe billing and a full test suite included. The trade-off here is no email/file storage/Docker deployment out-of-the-box.

Which Next.js SaaS template is best for beginners?
ixartz is a decent option for those who want to understand the inner workings of the SaaS auth/billing/database layer, and it's free. If you prefer a product that is already production-ready without having to assemble the pieces yourself, then Kostra makes that learning curve much smaller (with the trade-off of a one-time payment).

What are the best alternatives to the Bulletproof Next.js SaaS starter kit?
Free alternatives:
nextjs/saas-starter (official Vercel minimal starter),

boxyhq/saas-starter-kit (enterprise compliance focus),

create-t3-app (type-safe stack with no SaaS features built in; see our full T3 Stack vs Kostra comparison if you're considering this path).

Paid alternatives:
Kostra ($150, infrastructure flexibility, Docker)

Supastarter (advanced multi-tenancy, Lemon Squeezy support)

MakerKit (Supabase ecosystem, plugin system)

ShipFast (speed-focused for solo founders)

Nextjs SaaS Template: Free & Premium Options to Build, Launch & Scale Your SaaS

Prince — Thu, 09 Jul 2026 09:41:46 +0000

Selecting a Next.js SaaS template is not a single decision. A template that will bring you the first user will most likely be different from the one bringing you the first thousand. And the architecture decision embedded in the template at the early stages turns out to be your constraints at scale.

This guide offers the right context to the template selection decision by separating it into three distinct stages, each having its own requirements and trade-offs.

Why the Right Template Selection has a Lifecycle
While most articles on the topic of choosing a template present it as a static process ("Choose the best template and use it forever"), the truth is much more complex. While a free minimal starter is the right choice while validating a new idea with no users, at 1,000 paying users, your requirements are very different, as you need subdomain-based multi-tenancy, connection pooling, and a deployment architecture that is not tightly connected to Vercel's serverless function.

The template decisions you make at the early stages of development become your constraints in months. Sometimes – constraints that are actually correct decisions and allow smooth scaling. And sometimes – the surprise that appears as you scale and that comes from the choices you make while looking for speed and convenience of initial development.

This article is about making this decision with all three stages in mind.

Stage 1 – Build: What Matters Before You Have Users
When at the stage of building, you don't have any users or revenue yet, and your idea is not validated yet. At this stage, the template choice should focus on one thing only – getting to the first paying user as quickly as possible.

What matters at this stage
Auth that works out of the box. You shouldn't spend a day developing the authentication functionality in week one. The functionality includes signup, login, OAuth, and password reset. Everything should work after you just cloned the template and entered your environment variables.

Stripe checkout that closes the loop. Not only the checkout UI, but the webhook handler that would update your database after the subscription was created. This is the functionality that is mostly implemented incompletely and discovered too late by many founders.

Clean enough codebase to understand. If you cannot trace the data flow from user signup to the database in 30 minutes, the template is too complex for this stage. You need to know what you are building on top of.

Minimal stripping required. The template that ships with such features as blog management, feedback collection, roadmaps, and i18n forces you to waste a day removing the unnecessary stuff before you can start developing your application.

What doesn't matter at this stage?
Multi-tenancy, unless your product is a team tool by nature. Role-based access beyond owner/user. Docker support. Admin panel. Analytics dashboard. i18n. Dark mode customisation.

These are features that you will be adding when asked for them by your users. Not features that you will be developing prior to the users' appearance.

Free vs premium at Stage 1
Free wins at Stage 1 for most of the founders because the time required to learn the premium template is more than the time saved by its pre-built functionality, while you need only auth and billing to be working correctly.

The exception: if you have shipped a SaaS application before and exactly know what you are building, then the superior architecture and documentation of the premium template would save you the time from the first day.

Best free templates for Stage 1:

nextjs/saas-starter – official Vercel minimal starter. Auth.js, Drizzle ORM, Postgres, Stripe. Designed to be sparse. Minimal learning curve.

ixartz/SaaS-Boilerplate – most of the features, most actively maintained. Most stripping required but better foundation.

Stage 2 – Launch: What Breaks at Your First 100 Users
At the stage of launching, something happened. You already have real users performing the actions that you did not expect. The template decisions you made at Stage 1 are now encountering reality.

What breaks first
Webhook handler. All the SaaS billing problems sooner or later come back to the webhooks. User upgrades. Payment failure. Subscription cancellation in the middle of the cycle. If your webhook handler handles only checkout.session.completed event, every other subscription event is unhandled. Your database goes out of sync with Stripe. Users either lose or gain access incorrectly.

This is not a scaling problem; this is a correctness problem. It appears at your first 10 paying users, not at 10,000.

Check your webhook handler now, before launch:

// These events must all be handled

'customer.subscription.created'
'customer.subscription.updated' // ← the one most templates miss
'customer.subscription.deleted'
'invoice.payment_failed' // ← the second one most templates miss
'invoice.payment_succeeded'
Add them in your webhook handler if they're missing in your template.

Email deliverability.
Transactional emails (welcome, password reset, payment confirmation) that work during development won't necessarily work in production. Providers like Resend, Postmark, and AWS SES require domain verification and DNS record configuration. The email that works flawlessly in sandbox mode using an API key in your development environment will silently fail in production until you configure the SPF, DKIM, and DMARC records in your domain.

Check transactional email delivery end-to-end with a production email address instead of the provider's in-dashboard preview.

Onboarding drop-off.
The first time a user signs up and sees a blank dashboard, they'll leave and never return. The default empty state provided by your template is not an onboarding flow. It's a launch blocker that most templates let you solve.

Create a minimum viable onboarding flow before launching: a welcome screen, a one-time prompt to set up the dashboard, and a redirect to the first user action.

Session edge cases.
Auth libraries will handle 95% of session-related edge cases correctly. But 5% of those will manifest at launch time: sessions expiring and redirecting poorly, OAuth flows breaking in mobile browsers, account linking where a user attempts to sign in with a social provider matching an existing email/password account. Those aren't mistakes of your template. They are edge cases that require handling.

What matters at Stage 2
Error monitoring. Sentry or equivalent. You need to know when something breaks in production before your users do. Almost all premium templates include Sentry. Free templates rarely do.

Meaningful logging. Not just console.logs. Logs that allow you to see what happened when a webhook was triggered, what happened when a payment failed, and what happened when a user hit an error. This is the difference between spending minutes instead of hours debugging production issues.

A way to contact users. When something goes wrong in production, you need to reach the affected users. User management provided by your template should store an email address for each user and have a way to query users by a particular error.

Free vs premium at Stage 2
Premium templates pay off starting from this stage. The main difference between free and premium templates at Stage 2 is documentation and production experience.

Free templates come with a README file. In case your webhook handler is misfiring at 2 am and you want to understand how the subscription logic was implemented and why the README is not enough. Premium templates have detailed documentation of the architectural decisions behind the implementation. You'll need that documentation when something breaks in production.

Production-ready features like error monitoring, logging, and infrastructure configurations are also more consistent in premium templates. Free templates sometimes have Sentry. But they rarely have useful logging.

Stage 3 – Scale: What Your Template Choice Costs You at 1,000+
As you grow past 1,000 users, get revenue, and likely even hire people, the architectural decisions made in your template become compounded advantages or liabilities.

Scaling issues that come from the templates' architectural decisions
Multi-tenancy refactoring.
This is the most costly architectural problem a growing SaaS product encounters. If your data model scopes the records to the user level but not to the organisation, and you're growing towards the team/enterprise customers, you will need a full schema refactoring on a live production database.

Refactoring multi-tenancy implies adding an organisations table, adding an organisation ID foreign key to every domain model, adapting every query to filter by tenant, integrating your billing system to operate at the organisation level and making sure nothing gets lost while doing this on a live system.

A design that works for 100 users might fall apart at 10,000. Multi-tenancy is the heart of any SaaS product as it provides a way to securely serve multiple customers from one application.

A template that prioritises multi-tenancy from the start saves you this refactoring completely. A template that adds "support for teams" as an afterthought and doesn't pay enough attention to the data model design does not.

Database connection limitations.
Next.js serverless functions on Vercel create a new database connection with every request. In a low-traffic case, it's okay. With thousands of requests, you will exceed the maximum number of database connections and your queries start queuing or failing.

The solution is connection pooling with PgBouncer, Neon's native pooling or Prisma Accelerate. These are infrastructure-level settings, but depending on how your template is configured, you need different solutions.

For example, templates that are meant to be deployed in the traditional way, e.g. Kostra's Docker support, do not suffer from this problem as long-running server applications create database connection pools naturally.

Subdomain-based tenancy.
Consumer SaaS can usually be run on yourapp.com/dashboard. Enterprise B2B SaaS usually requires customer.yourapp.com. Subdomain routing requires middleware-level configuration, wildcard DNS records and custom domain support for bigger customers.

Subdomain routing gives you the best combination of factors: professional URLs that allow custom domain usage, natural security boundaries and efficient codebase scalability. That's why platforms like Slack, GitHub and Shopify all use subdomain-based architecture.

When your template doesn't include subdomain routing in its middleware, implementing this later involves a complete overhaul of the routing layer while the product is alive.

Auth service price at scale.
Templates using Clerk, Auth0, or other hosted auth providers have a monthly price per monthly active user. At 1,000 users, it's acceptable. At 50,000 users, hosted auth cost becomes a notable line item that wouldn't appear at all if you were using self-hosted auth (e.g. Auth.js or custom JWT).

This is not a reason not to choose Clerk at Stage 1. This is a reason to understand that the price of the auth provider in your template will scale in ways that don't happen early on.

Deployment infrastructure.
Serverless functions provided by Vercel are great for the majority of SaaS products regardless of scale. However, there are products that outgrow them: background jobs that run continuously, WebSocket connections, intensive CPU processing, etc.

Some products have special data residency requirements that require an AWS region that isn't available on Vercel. Templates that assume Vercel deployment create migration costs when such things are needed. Templates with Docker support can be deployed anywhere from day one.

What matters at Stage 3
Architecture patterns that scale. Database access via the repository pattern implies query centralisation and cacheability. Service layer business logic makes it possible to implement caching, queuing, and background processing without rearchitecting core logic. The templates that work at scale include these patterns.

Multi-tenancy in the data model. Not as a feature. As an architectural pattern upon which every domain model is based. Every query has a scope of a particular tenant. Data leakage between companies becomes impossible, not just policy-controlled.

Deployment flexibility. Docker, connection pooling, flexible infrastructure. The less flexible the template deployment assumption is, the higher the cost of its deviation will be.

Active maintenance. Security patches, dependency upgrades, compatibility with new framework releases. When the template is used at scale, your company can’t afford to maintain the template. This responsibility should be delegated to somebody else.

Free vs premium at Stage 3
Premium wins decisively at Stage 3.
At Stage 3, the premium templates win definitely. The compounding effect of better architecture, active maintenance and deployment flexibility becomes more obvious when there are real users, real revenues and real engineering restrictions.

Free templates maintained by one person aren’t guaranteed. Updating happens whenever the maintainer has time for that. When at Stage 3, your business relies on being up to date with the infrastructure layer – this dependence should be supported by commercial interest.

Developers who are getting the most from premium templates are those who have shipped SaaS before, know what they're building, and have something that's worth putting effort into validating. The developers who pay too much for premium templates are those who buy a $400+ full-featured starter template, waste a week understanding how it works, strip half of its features out, and find themselves able to use the free minimal starter and get there quicker.

Match the investment to the stage.

The Template Decisions That Compound Over Time
The Template Decisions That Compound Over Time

This is where we're talking about architectural decisions of the template that have long-term implications for your product. Definitely worth making an evaluation explicitly before picking a template.

Is multi-tenancy in the data model or the application layer? Data model multi-tenancy: There is an organizationId foreign key on each domain object. Filters in all database queries are done by the tenant at the database level. Missing WHERE is not going to allow data to be leaked, as the schema itself provides for tenant scoping.

Application layer multi-tenancy: You manually filter organizationId on all queries. Tenant scoping is done through developer discipline. Missing WHERE leaks data across tenants.

The former is the right way to go; the latter is a potential security and correctness hazard that increases with the codebase size. Evaluate which approach a template uses.

Is auth self-hosted or vendor-hosted? Self-hosted (Auth.js, custom JWTs): User data in your database. No per-user pricing. Full control over the system. More upfront configuration needed.

Vendor-hosted (Clerk, Auth0): Managed infrastructure. More features come out-of-the-box. Per-user pricing at scale. User data in vendor-managed servers.

Both approaches work. This difference matters in cost predictions at scale and for products with data residency needs.

Does the template have a layered architecture?
A template that allows separation between business logic, database queries, and API routes through layers (services, repositories, API routes) is much easier to maintain, test, and extend as a codebase scales. A template where database queries are scattered around the codebase in API route handlers generates technical debt, which accumulates every time you add another feature.
What is the deployment model?
Vercel-only templates are quick to deploy and best for any purpose. They cause migration costs when you need Docker, self-hosted, or specific AWS region deployment. Templates with Docker support are portable right from the start.
How active is the maintenance?
Check the last commit date. Check the open vs closed issues ratio. Check how quickly the maintainer replies to new issues (within days or weeks). A template that isn't being actively maintained means that your team will have to do the maintenance of the infrastructure layer, which was supposed to save you from that very problem.

Best Templates by Stage
Stage 1 (Build/Validate)
Free: nextjs/saas-starter (Vercel official) - the cleanest minimal foundation, lowest learning curve, always up-to-date with Next.js

Free (feature-complete): ixartz/SaaS-Boilerplate - most features available, active maintenance, some stripping needed

Premium: Kostra - worth paying for if you've shipped SaaS before and need a production-ready architecture out of the box

Stage 2 (Launch/Early Users)
Free: ixartz/SaaS-Boilerplate if you haven't moved away from it yet. Active maintenance becomes more important as you go live.

Premium: Kostra - $150 one-time payment, production-grade authentication, billing and layered architecture. Documentation explains the whys of design choices, not only the hows. Worth it when you get to debugging production issues and saving time matters.

Stage 3 (Scale/Growth)
Free options start to show their limitations at this point. Maintenance and architecture gaps become actual costs.

Premium: Kostra - layered architecture (Atomic Design + repository pattern + service layer), multi-tenancy implemented as a data model concern, support for AWS S3/R2/SES, Docker deployment. Built with scalability in mind. $150 one-time payment for a foundation that doesn't require rearchitecture at scale.

For enterprise B2B: Supastarter or MakerKit for deep multi-tenancy. BoxyHQ for SAML SSO and compliance.

FAQs
What is a Next.js SaaS template?
Next.js SaaS templates come with the plumbing required for SaaS products: auth, subscription billing, DB schema, admin panel, and landing page. You clone it, configure your API keys, and extend it with your own functionality. Terms 'template', 'starter kit', and 'boilerplate' are synonymous in the Next.js universe.

What is the best free Next.js SaaS template?

ixartz/SaaS-Boilerplate is the most feature-complete free option with maintenance, multi-tenancy, Clerk auth, and Stripe billing. nextjs/saas-starter is the cleanest minimal option by the Next.js team. If you build an enterprise B2B SaaS with SAML SSO, the free boxyhq/saas-starter-kit covers all compliance issues other templates neglect.

Is a free Next.js SaaS template good enough for production?
Yes, at Stage 1 and 2, but with some caveats. Free templates perform well for MVPs, product validation and customer acquisition in the early days. The problems arise as the company grows. Reliability of maintenance, architectural decisions about multi-tenancy and flexibility in deployments become bottlenecks. If you build something that will be used by thousands of users, the architecture of your template is more valuable than its price.

What is the best premium Next.js SaaS template?
It depends on your requirements. Kostra is a $150 template suitable for production and B2B teams that require layered architecture, flexibility in infrastructure (AWS S3, Cloudflare R2, AWS SES, Docker) and active maintenance. ShipFast has a solid reputation among solo founders who aim for a fast product launch. Supastarter is the best option for complex multi-tenant B2B SaaS. MakerKit is great for teams using the Supabase stack.

How does a Next.js SaaS template affect scaling?
Architectural decisions in your template become constraints while scaling. If you have multi-tenancy implemented at the data model level, it scales perfectly fine. Multi-tenancy at the application level requires costly refactorings under the live product. Cost of auth vendor pricing grows with the user base. Deployment assumptions (e.g. only Vercel vs. Docker) cause migration costs when you outgrow them. Abstract architectural decisions in templates become actual costs and engineering challenges during stage 3.

When should I upgrade from a free to a premium Next.js SaaS template?
Three main indicators: you already have an MVP with paying customers, it works, but you decide to rebuild it using proper architecture, your team became bigger and free templates architecture doesn't allow working in parallel, or your infrastructure requirements (Docker, AWS, SES) go beyond what free templates provide. It is usually premature to upgrade before validation, and sometimes a false economy to remain on free templates after validation.

What makes a Next.js SaaS template production-ready?
Six things: auth that supports all edge cases (OAuth account linking, session expiration, server-side route protection); a Stripe webhook handler for all subscription events; structured logging & error monitoring; multi-tenancy that is implemented at the data model level, not the application; active maintenance with up-to-date dependencies; and good documentation explaining the architecture behind the template.

Best Free Next.js SaaS Templates on GitHub: Ship Your MVP Without Starting From Scratch

Prince — Thu, 09 Jul 2026 09:35:38 +0000

Most developers who clone a free Next.js SaaS template spend the first week configuring things that don't matter yet. They adjust the email templates before having any users. They implement i18n for a product that is going to launch in one language. They spend two days configuring the admin panel before the first sign-up.

And then they wonder how it took six weeks to launch something they believed could be launched in just two.

This article is about the gap between cloning a free starter template and shipping your MVP. What that gap is. How large that gap is. What fills that gap unnecessarily? And what the actual sprint from cloning to a live product looks like.

What an MVP Actually Is (And Isn't)
An MVP is the smallest version of your product that people will actually pay for. Not a demo. Not a prototype. Not a landing page with a waitlist. An actual working product that solves some concrete problem enough to make someone pay for it.

The key phrase here is "will actually pay". A lot of people will be willing to use a free product. Fewer will buy it. Being ready to accept the payment is the actual validation milestone. Everything else is assumptions.

What an MVP is not:

It's not a finished v1 release. MVP doesn't require any perfect UI, dark mode, or changelog. It requires solving a problem reliably.

It's not feature-complete. MVP is meant to be embarrassingly feature-incomplete to be launched. If it's not, you've built too much.

It's not multi-tenant. Unless your product inherently works for several teams (collaboration tool, B2B product with multiple clients), you can postpone multi-tenancy and add it later when you'll actually need it.

It's not just a landing page with future features planned to be implemented. MVP is something you can show to your potential users and use yourself.

Your MVP tests one assumption. Not three. Not "the whole vision but with simpler implementation". One. Such discipline is what separates the founders who launch their MVP in four weeks from those who spend six months doing so.

What a Free SaaS Template Can Give You vs What MVP Requires
This is the biggest misunderstanding most developers have when starting.

What a good free template can give you
Working auth (signup, login, password reset, OAuth)

Connected database with migrations

Integration with Stripe and at least a basic subscription flow

Dashboard shell with navigation

Landing page with pricing section

TypeScript and basic tooling setup

All those things would take you roughly from three to six weeks of work if done from scratch. A free template reduces this to a day or two of configuration.

What your MVP additionally needs
Your core feature. The one feature your product has that people pay for. Completely yours to implement. A free template cannot cover it.

A working onboarding flow. What happens after sign-up? If a new user lands on an empty dashboard, they'll be leaving soon. At least three pages you'll need: welcome screen, setup prompt, and a page with some first action.

Transactional email. Welcome email, password reset email (it usually comes pre-bundled), and payment confirmation email. Simple, but required.

Error states that don't look broken. Empty states, loading states, and error messages. Your users will encounter all of those during their first session.

A way to collect payment. Yes, it's obvious, but still. Many MVPs are launched without having their Stripe integration finished end-to-end. The checkout needs to be working, the webhook needs to update the database, and the user should get access instantly after payment.

What your MVP does not need
This list is longer than most people assume. None of those things is actually required for your first paying user:

Multi-tenancy and organisation management

Role-based access control beyond owner/user

i18n and multi-language support

A blog or content management system

An admin panel for managing users

A public API or webhooks for integrations

Dark mode

Mobile app

Analytics dashboard beyond basic Stripe revenue

Automated onboarding sequences

In-app notifications

User feedback collection tools

Changelog or roadmap pages

SSO or SAML

Each item on that list is a part of a well-featured free template. Each of them is something you can remove from the template.

The Three Decisions That Kill MVP Momentum
Those patterns come from personal experience building and launching products. They cause the majority of the delay between the 30-day MVP and the 6-month one.

Decision 1: Choosing MVP features based on what the template has
The template has a blog. You don't need a blog. However, it is there. And now you start thinking about the content strategy. You start adjusting the MDX editor. Days pass.

It's the most common momentum killer. The feature set of the template is not the feature set of your product. Everything the template has is something you can configure and use or remove completely. There's no third variant like "will improve later".

Before coding anything product-related, strip the template down to its bare minimum. Remove the blog if you don't launch with the content. Remove the feedback collection tool. Remove the roadmap page. Remove the i18n setup. Run npm run build, fix import errors, and you have a much clearer starting point.

Decision 2: Over-engineering the data model before validation
The correct data model for an MVP is the simplest one that supports your core feature. And you will never know it until you'll get some user feedback after one month of usage.

All the founders trying to design the "perfect" data model before the product launch consistently tell me one and the same thing: they had to rewrite a significant part of it after receiving the feedback. Time spent designing a pre-launch schema was basically wasted.

The rule here is very simple: add the column when you need it. Add the table when you need it. Migrations need to be small and frequent. Don't engineer the schema for a future product state.

Decision 3: Treating the checkout flow as a last step
It is the main reason why more MVPs are delayed than anything else. Checkout process touches many systems: Stripe products, webhook handler, database tables, subscriptions statuses and access control, UI after payment. And this process is longer than founders expect and may lead to financial losses.

Founders treating the checkout as the last thing to code lie. Those who commit often realize that the bugs found in the final week delay the launch or worse - launch with a non-working checkout losing paying users.

Implement checkout flow in the first week. Test it with Stripe test cards before implementing any other product features. Verify that:

A user can complete a subscription

The webhook updates the database

The user gets immediate access to paid features

A cancelled subscription removes that access

A failed payment sends an email and the right thing happens in the UI

Do this before implementing any of your product's features. The checkout is not a feature, it's infrastructure. Treat it like authentication.

The 30-Day Sprint: Clone to First Paying User
Here's a realistic schedule for a solo developer with a clear MVP concept using free Next.js SaaS starter.

Day 1-2: Clone, configure, strip
npx degit ixartz/SaaS-Boilerplate my-product

cd my-product

npm install

cp .env.example .env.local

Add environment variables. Connect a free Neon or Supabase database. Configure Clerk (free tier). Configure Stripe (test mode). Run npm run dev. Verify auth works end to end: signup, verification email, login, dashboard.

Then strip. Strip out any features your MVP does not need. Blog system, user feedback collection, roadmap, i18n, changelog. Delete. Run npm run build. Fix any broken imports. You now have a clean foundation to build on.

End of Day 2 goal: Template is running locally, auth is configured, and extra features are stripped.

Day 3-4: Checkout flow, from end to end
Set up your Stripe products and pricing tiers. Update your template landing page pricing table accordingly. Implement the checkout session creation. Implement or verify the implementation of webhook handling for all relevant Stripe events. Test with Stripe test cards:

4242 4242 4242 4242 - successfully authorised payment

4000 0000 0000 9995 - payment is rejected

4000 0025 0000 3155 - payment needs authentication

Verify that after a successfully authorised test payment, your subscription status is updated in the database and the user can access paid content.

End of Day 4 goal: User can sign up, subscribe and access paid content.

Day 5-7: Core feature, first version
This is the only week you should focus solely on making the feature unique to your product. One feature. This is why users are going to pay for your service. No additional polish, no edge cases other than obvious. Just something functional.

Ask yourself this question at the start of each day: "Do I have this core feature built, or am I dodging it?"

End of Day 7 goal: Core feature is built. The user can sign up, pay, use it and get value from it.

Day 8-10: Onboarding flow
What do you do after signup? Figure it out right now, don't postpone it. At minimum:

A welcome screen that explains what to do first

Prompt to complete some necessary task (connecting to an external service, setting up a project, filling out their info)

A redirect to the first meaningful action

People who don't know what to do after signing up don't come back. There's nothing optional about this for a launch.

End of Day 10 goal: New user can navigate through signup to the first meaningful action.

Day 11-14: Error states, empty states, edge cases
Explore every screen of your product as a new user. What does each screen show to the user when there's no data available on it? How does your product behave when an API call fails? How does your product notify the user if a payment fails?

Error states are more important than polish. Empty states that provide instructions are a feature of your product.

Handle the obvious errors and edge cases. Do not strive for perfection. Strive to have nothing visibly broken in your app.

End of Day 14 goal: No screen in the application is broken for new users.

Day 15-17: Transactional emails
Configure and test:

Welcome email on signup

Password reset (you might already have it set up from the template)

Email notifying the user about subscription activation

Don't overcomplicate this. Plain-text email is better than a beautifully designed email that goes to spam. Test the delivery to a real email address, not just the preview in your email provider.

Day 18-21: Landing page
Replace the generic content of the landing page provided by the template with your product specifics. Replace generic hero text with your specific value proposition. Replace the generic features list with your features. Replace the generic pricing section with your actual products and pricing provided by Stripe.

A landing page does not need to be fancy. It needs to clearly answer three questions: What is it doing, who it's for and what it costs.

End of Day 21 goal: A stranger coming to your landing page can clearly understand what the product is and start the trial or subscribe.

Day 22-25: Internal testing
Test your own product as a paying customer for three to four days. Sign up. Subscribe with a test card. Use the core feature. See if you can break it and fix everything broken.

Recruit two or three people who will do the same testing. Not your friends who will be nice. The people who will tell you when something is wrong.

Day 26-28: Production setup
Switch Stripe to live mode. Add all production environment variables. Deploy to Vercel. Test a complete subscription flow using a live credit card and a live user. Test emails for delivery and webhooks for firing in the production environment.

It always takes more time than you think. Allocate two days to production setup.

Day 29-30: Announce
Tell those people who have the problem that your product solves. This is not a launch announcement to the internet. Tell ten specific people in communities or DMs that you built something to solve their problem, and here's a link.

It's not about virality. It's about one paying customer. One person who is willing to pay because your product solved a problem for them. It's worth more than another six months of development.

What to Defer to v2 (The List Most Guides Skip)
These are the most common features that developers add before launch when it was not necessary at all, and prevented them from validating their MVP. Don't build these in advance of validation.

Multi-tenancy and organisations. Unless your product is inherently a team tool, single-user accounts are enough. Only after you have paid for single-user accounts will they request you to add organisations.

Role-based access control beyond basic. Owner and member. That's all you need at the MVP stage. Complex role-based access control with custom permissions is something enterprise customers ask for.

Admin panel for managing users. Initially, you will have so few users that direct database access will be enough. Add the admin panel after you have so many users that managing them manually becomes difficult.

i18n and localisation. Initially, you can launch in one language. Add languages when people in other languages start using your product.

A blog or content marketing system. Content marketing is your growth channel, not an MVP feature. Launch your product first.

API and webhooks for integrations. You need to know whether people pay. You don't need cohorts and funnel visualisation until you have enough users to analyse.

Analytics beyond Stripe MRR. You need to know if people are paying. You don't need cohort analysis and funnel visualisation until you have enough users to analyse.

Mobile app. First, launch on the web. Then, add mobile after web users ask for it, and you have enough resources to maintain both surfaces.

Dark mode. It's in the template. Leave it. Don't waste your time on this. Nobody chooses your product over a competitor because of dark mode.

User feedback widgets and roadmap pages. Talk to users directly. Email them. Schedule calls. In-app feedback is useful when you have scale. At the MVP stage, direct communication is more informative.

Which Free Templates Are Worth Starting With
Based on actual maintenance status and MVP suitability, not just feature count.

ixartz/SaaS-Boilerplate
The best free template for an MVP requiring multi-tenancy from the very beginning. Upgraded to Next.js 16. Auth via Clerk, Stripe billing, Drizzle ORM and Shadcn UI. Many features included in this template mean that you need to do more stripping, but the architecture is solid.

Good for: MVPs with teams or organisations as the core model.

GitHub: github.com/ixartz/SaaS-Boilerplate

nextjs/saas-starter (Vercel official)
The cleanest starting point for a simple single-user MVP. Auth.js v5, Drizzle ORM, Postgres and Stripe. Intentionally minimal. Fewer features to strip means fewer headaches for simpler MVP.

Good for: MVPs that are meant for solo founders and need to understand the entire codebase.

GitHub: github.com/nextjs/saas-starter

KolbySisk/next-supabase-stripe-starter
A clean starter for Supabase + Stripe stack. Feature-based code structure. Stripe Fixtures that simplify reproducible product configuration. Less popular than ixartz, but often better for simpler MVPs.

Good for: Developers who are committed to using Supabase and want a clean starting point.

GitHub: github.com/KolbySisk/next-supabase-stripe-starter

When a Free Template Isn't Enough
Three cases when a free template would not cut it, and you should consider going for a paid one:

You have validated your MVP, and you're building v2.
Your MVP was successful. You have paying customers. You rebuild with the proper architecture. This is the moment when you should invest in a paid starter that will have better multi-tenancy, documentation and guarantees.

Your product requires additional infrastructure not covered by free templates.
AWS S3, Cloudflare R2, AWS SES, Docker deployment. If your requirements differ from what's covered in free templates, you'll be wasting more time figuring out how to fit your product into the template rather than building the product itself.

Your team has grown.
A solo founder with a free template is fine. A team of three working on the same codebase needs better architectural discipline. The layered architecture patterns that paid starters have become relevant when multiple developers are working simultaneously.

Kostra is worth considering at this point. $150 one-time fee. Includes AWS S3 and Cloudflare R2 file storage, Resend and AWS SES email, Docker deployment, Prisma with any PostgreSQL provider and a layered architecture built for team development. It's built for the stage after you have validated your free-template MVP.

FAQs
How long does it realistically take to go from a free Next.js template to a live MVP?
With focused work and a well-defined product scope, four weeks is realistic for a solo developer. A focused MVP is usually between 8 and 12 weeks for a dedicated team. Using a free starter kit allows you to reduce the infrastructure setup time from weeks to days. The bottleneck of development will always be your product's core feature, not the scaffolding. Most MVPs that take longer than four weeks are either poorly scoped, have too many features or wasted time on launch-irrelevant polish.

What should I strip from a free SaaS template before developing my MVP?
Anything that your MVP doesn't specifically need: i18n if you launch a single-language product, blog system if you're not going to launch with content, user feedback and roadmap tools, changelog management, admin panel if you can manage users manually, and any auth providers you won't use. Then run npm run build and fix any broken imports. You'll be left with auth, billing, clean database schema and your core UI structure.

What is the minimum required for a MVP launch?
Auth that works end-to-end (signup, login, password reset), checkout flow that processes payments and updates the database, the core feature that users pay for, onboarding flow for new users to help them find the first actions, and landing page explaining what the product does and what it costs.

Should I implement multi-tenancy in my MVP?
Only if your product is inherently a team tool. If individual users can get value from your product without organizing themselves into teams, launch with single-user accounts. Multi-tenancy is a meaningful architectural addition that takes significant time to implement. Implement it when you have paying users requesting it, not speculatively.

Which free Next.js SaaS template is best for quick MVP launch?
For a simple single-user MVP: nextjs/saas-starter (minimal, official and easy to understand). For a multi-tenant MVP where teams are central: ixartz/SaaS-Boilerplate (most complete free option). For Supabase stack: KolbySisk/next-supabase-stripe-starter (clean code structure, good Stripe integration).

What's the biggest mistake developers make when using a free SaaS template for an MVP?
Building features the template includes rather than features their users need. Free templates include blogs, user feedback collection, roadmaps, i18n, admin panel and so on. None of these is MVP feature for most products. Developers who don't strip the template first spend their first two weeks in the wrong codebase, customising the features they'll be removing in v2.

When should I upgrade from a free template to a paid SaaS starter?
When your MVP is validated by paying customers and you're rebuilding with proper architecture, when your team has grown beyond a solo founder, or when your infrastructure requirements (Docker, AWS S3, AWS SES) exceed what's supported by free templates. Buying a starter kit beforehand is often premature. After validation, the quality of the architecture of your foundation becomes a limiting factor for how fast you grow.

What Developers Think About Next.js SaaS Starters on GitHub

Prince — Thu, 09 Jul 2026 09:32:00 +0000

Comparing the most useful boilerplates is like comparing the most interesting movies – people write them without having used their picks in real projects. The reviews based on features alone and copying bullet lists from landing pages are everywhere.

In this article, I rely solely on comments and discussion patterns from the r/nextjs, r/SaaS, Hacker News, and dev.to communities, and try to convey the experience of developers who have already gone through building apps with starters. And what they learned in the process.

What the Developer Community Agrees On
Here are a few topics where opinions in the community converged after years of discussion.

Stars lie. Commits don't.

This pops up in almost every single discussion regarding Next.js starters. Why would you ever consider a repository with 6,000 stars but last updated 14 months ago as the basis for a project in 2026? The author of the library moved to a different stack. The dependencies haven't been updated for ages. The authentication pattern they use in the example is outdated. Stars show that it was a good thing at one time in the past. Commits show whether it's actively developed and maintained now.

Always check the date of the last commit on the GitHub page before diving into anything else.

"Production-ready" means almost nothing.

It's hard to count how many Next.js starters call themselves "production-ready". But here is what that really means – active dependency management, properly set up security headers, environment variable validation during startup, proper route protection from unauthorized access, and, finally, a Stripe webhook handler covering edge cases. None of the boilerplates I tested ticked off all five boxes. So don't believe the hype. Always check them one by one.

The first week decides everything.

According to multiple developers discussing starter kits in various threads, there's a pattern. If you managed to make the boilerplate run, wire it to Stripe's test API, and have a user create an account and sign up for a subscription within the first day or two, then it will prove valuable throughout the development process. However, if you spent the first week fixing configuration errors and reading outdated documentation, it was the wrong choice. Test the demo. Try running it before committing.

Free boilerplates are good enough for MVPs, not for scale.

While you might think that the general recommendation from the developer community is "paid good, free bad", in reality, it is much more nuanced. Free boilerplates are indeed capable of building MVPs, as the name suggests. The difference between free and paid shows itself six months down the line. The free starter doesn't track a security update, or you find out that the architecture of multi-tenant apps needs changes in order to implement the new feature requested by your paying users. This is when the quality of maintenance and architectural decision of what you start with turns against you.

The Template vs Starter Kit Distinction (That Actually Matters)
Asking developers about the distinction between a template and starter kit yields clear answers.

A SaaS template is a starting point for visual design. You get layout templates, pre-made pages with styles. The template can provide such features as a login page and dashboard shell, but no further integration. You won't get working authentication mechanism, Stripe webhook listener, database migration schema or route protection.

A SaaS template is what you usually buy on ThemeForest. You get a visual skeleton to implement functionality.

A SaaS boilerplate or a starter kit is a complete, functional app. The login flow is implemented, the billing works, the database schema is created with migrations, and everything is protected. When you clone the project, fill in the variables, and run npm run dev, you get a running product with a registration flow, payment processing, and dashboard protection.

Why this distinction matters in practice:

Users looking for "Next.js SaaS template" often expect a starter kit. Finding the opposite in their search leads to disappointment and posts in community forums.

Before downloading any source code, ask yourself: does it work out-of-the-box with working authentication and Stripe in the test mode? If yes – you found a starter kit. If you see an incomplete structure with placeholders to be replaced with your code, you found a template.

Both concepts are completely fine in their purposes.

What Reddit Says About Free vs Paid
Community discussions about free vs paid starters are extensive. Here's an honest synthesis of the recurring patterns.

The case for paying, in developers' own words
What comes across again and again in developers who shipped their products using paid starters? "You're paying for maintenance, not features." If you use a free starter, you rely on the person who maintains it having enough interest and available time to support it. With a paid starter, there's more of an incentive to keep it updated.

Secondly, "documentation". The free starters come with README. The paid ones – with actual documentation where you can find answers regarding architectural decisions. You need that in case you're facing any edge cases after six months from launch.

One particular example from HN discussions: "Use supastarter when you build something complex" due to the clean architecture and the way the code is written. And ShipFast when you need to ship a product and be done with it (for solo founders). When people recommend a starter, they tend to recommend a paid starter for everything else except MVP validation.

The case against paying, in developers' own words
In this case, there are usually two major points of frustration with paid starters.

The first being the fact that you're trying to build something different from the starting point, which is impossible due to its architecture. A typical example given: you bought a Clerk-based starter but then changed your mind about storing user data in your database. Well, then you refactored that entire authentication, and the paid starter helped you nothing at all.

And the second point: an excessive number of features. Some devs found themselves forced to pay for a kit that had built-in capabilities of managing blogs, collecting feedback, implementing roadmap screens and changelog tools. They wasted days removing the excess from the code.

Advice that tends to come after such stories from people: "Run the starter before you buy. Read the documentation before you buy. Know which features will be stripped out before you see the list."

Where the community lands
So what is the verdict coming from r/nextjs, r/SaaS, and Hacker News discussions?
Not "paid is better than free".

Validating an idea: Free starter. The ixartz SaaS Boilerplate or the Vercel official starter.

Building a product you intend to grow: Paid starter with active maintenance and architecture that matches your requirements.

Enterprise B2B with compliance requirements: BoxyHQ's free starter, possibly combined with a paid option for the app layer.

What Developers Actually Complain About
These problems are drawn directly from discussion threads in community forums, where multiple developers independently make the same comment about their experience. These issues span products and aren't specific to individual starters.

"The webhook handler only covers the happy path"
This is hands-down the most frequently reported production complaint about starters in general. A developer releases their SaaS, a customer upgrades their subscription halfway through the payment cycle, and their application stops working. Why? Because the webhook handler included in the starter only accounted for checkout.session.completed, and nothing else.

Preventative action: Open the webhook handler code in the starter you're considering. Count which Stripe events it's set up to handle. Make sure customer.subscription.updated, invoice.payment_failed, and customer.subscription.deleted are included. If not, include them now before developing any other parts of your product.

"The multi-tenancy wasn't real"
Common criticism of multi-tenancy starters, specifically: all data is scoped to a user account, not a business/organization. You can add users to teams, but all data managed by the starter application only has a userId foreign key, no organizationId. Users belonging to two different organizations do not have isolated data.

Dev reaction: Painful refactoring effort when caught later. Pre-build prevention: Check prisma/schema.prisma file in starter. Look for whether each domain object has an organizationId field. If it does not, it's user-scoped data, not true multi-tenancy.

"The documentation got me to day one but not to day two"
Common feedback from starter kit users about free kits. Documentation provided in the form of README.md takes you through getting started with the starter. But when you want to add another feature, modify the database schema, or even figure out what was considered best practice for making certain architectural decisions, the source code is it.

Documentation gap between free and paid. The kind of issue raised multiple times in community forums. With paid starters, you typically receive detailed explanations of the reasoning behind the choices made.

"I spent three days fighting someone else's auth setup"
Repeated complaint: copied starter, encountered configuration conflict with auth code, spent days wrestling with configuration problems instead of building my own feature. Usually caused by using an old version of either Clerk or Auth.js. Versions which underwent API breaking changes between when starter was built and when dev clones starter.

Prevention: Check version of auth library in starter's package.json. Compare against latest release notes for said library. Significant version differences usually indicate deprecated authentication functionality in the starter.

"I was paying per active user and didn't notice until month three"
This specific complaint relates to Clerk. Clerk offers a generous free plan limited only by number of monthly active users. But once you go above that threshold, you start paying per user. This is a common problem reported by devs in community forums when their application scales past the free-tier limit, unbeknownst to them.

Not a reason to avoid Clerk. Just a reason to familiarize yourself with the pricing page before deciding which starter to use.

What Developers Actually Praise
Positive comments made about boilerplates by developers are equally predictable in forums.

"It saved me at least a month"
Average estimate for time saved in development by using a starter kit ranges from one to four weeks across satisfied developers' comments. Authentication, billing, multi-tenancy, emails, dashboard layout – all of these together can take several weeks to implement. Those who express highest level of satisfaction are those who knew what they were looking for ahead of time and picked a starter matching their architectural needs.

"The community got me unstuck"
Starters accompanied by active Discord server or Slack channel. Huge value proposition for someone stuck with an urgent problem to solve in the middle of the night. Most frequent positive mentions are from developers of ShipFast and Supastarter.

"The architecture held up"
Positive comments made about starter kits whose architecture allowed the developer to easily add more functionality. Examples: "Added six months later the ability to [major new feature] and it fit perfectly into existing starter pattern". Comes up most frequently in relation to Supastarter multi-tenancy architecture and layered architecture starters such as Kostra.

The negative version: "Had to completely refactor [billing/auth/data] layer because the starter kit architecture couldn't accommodate [my requirements]."

"The demo site matched reality"
Minor detail which makes the biggest impact. Satisfaction expressed by developers whose starter kit of choice has an actual demo running off the starter itself. Landing pages for some starter sites look far fancier than the codebase they actually contain. Demo sites that load quickly and demonstrate all advertised capabilities are a sign of good product quality.

Which Next.js SaaS Template Is Best for Solo Founders?
This question pops up on Reddit all the time, both in r/SaaS and r/nextjs communities. Here's what they say on the matter – not always what the guides will recommend.

The ShipFast question
ShipFast used to reign supreme on this discussion, having been the default recommendation for solo founders who needed to "ship fast." The ShipFast consensus in the community has always been the same: great documentation, huge Discord community, quickest route to deployment with auth and billing included.

Note: according to community data, ShipFast was discontinued as of 2025. Please make sure to verify the availability of the template before making any purchases in any older discussions recommending ShipFast.

What solo founders actually need
Solo founders need something very different from what teams need, based on what the discussions have taught us – they are more likely to pivot. You build something, you get some early users, realize what the market wants and needs to change direction. Being able to add features easily matters more than having everything built in.

The recommended pattern in 2026 by the community for solo founders is as follows:

If this is your first time making SaaS: Start with the free ixartz SaaS Boilerplate or Vercel's own starter. Get familiar with what you're building before you pay for it – you'll cover more than you need with these.

If you've made SaaS before: Judge the starters by the quality of their architecture. The most recommended ones by experience solo founders are those that make adding new features easy, regardless of their number.

If you're under real-time pressure: It's better to pay and get a good, documented starter with an active community. You'll save time on debugging other people's code rather than spending time on it yourself. The recommended ones here include Kostra, Supastarter, and MakerKit.

The solo founder mistake the community mentions most
Choosing the most expensive or most feature-packed starter as the "safest" choice. Several developers mentioned experiencing this in community threads: purchasing a $400 starter packed with 30 features, spending an entire week getting to know the codebase and stripping out 20 features that were not necessary. They wish they had gone with a simpler option.

The community advice: purchase the starter that best matches your needs, not the one surpassing them by far.

How to Find a Next.js SaaS Template on GitHub
An overview of how to navigate GitHub for finding these templates efficiently.

GitHub Topics (most reliable)
GitHub Topics are community-driven tags. The most helpful ones here are the following:

saas-starter-kit - curated, high signal

nextjs-boilerplate - broader but well-populated

nextjs-saas - specific to SaaS + Next.js

saas-boilerplate - overlaps heavily with saas-starter-kit

Navigate to github.com/topics/saas-starter-kit and sort by Recently Updated. This immediately filters out abandoned projects.

Search queries that work
language:TypeScript topic:saas-starter-kit

language:TypeScript nextjs saas boilerplate stars:>500

The language:TypeScript filter is useful because JavaScript-only boilerplates are typically less maintained. The stars:>500 threshold filters out single-developer experiments.

What to look at before reading code
In this order:

Last commit date (top right of the repo page)

Open/closed issue ratio

Next.js version in package.json

Whether proxy.ts or middleware.ts exists (indicates Next.js 15 vs 16)

The README setup time estimate

If all five look good, read the actual code.

Directories that curate starters
Beyond GitHub itself, these sources aggregate and vet Next.js SaaS starters:

Vercel Template Gallery (vercel.com/templates) - Vercel-curated, deploy directly

BoilerplateHub (boilerplatehub.com) - Vetted by developers, organized by stack

SaaSBoilerplates.com - Directory with stack filtering

These are useful for discovery. Always verify the last commit date on the actual GitHub repo before using anything you find there.

FAQs
What is the best free Next.js SaaS template in 2026?
Based on community mentions and active maintenance, ixartz/SaaS-Boilerplate stands out as the best free Next.js template for multi-tenant SaaS. nextjs/saas-starter is the recommended clean minimal template for learning purposes or creating a strong foundation. boxyhq/saas-starter-kit is the best free starter for B2B SaaS with SAML SSO. Although OpenSaaS (based on Wasp Framework) has the most stars, it is the best in a class of its own.

How do I find a Next.js SaaS template on GitHub?
Search by using the GitHub topic saas-starter-kit and sort by Recently Updated to eliminate any dead project. For targeted search, use the following query language:TypeScript topic:nextjs-saas in the GitHub Search field. Verify the latest commit date and Next.js version in the package.json before proceeding with the setup of any project. The Vercel Template Gallery and BoilerplateHub are good resources for discovering starters.

What is the difference between a SaaS template and a SaaS starter kit?
A SaaS template has mostly design elements such as pages, layout, components. In addition, it includes a complete login page and a basic dashboard interface but no infrastructure. Therefore, developers are required to build their implementation of business logic from scratch. A SaaS Starter kit is fully-fledged application where the authentication process works fine and has proper integration with Stripe. Clone it and update env files to run the application. The distinction helps avoid confusion among beginners looking for starters in terms of templates.

Which Next.js SaaS template is best for solo founders?
If it's the first product, free starters such as ixartz SaaS Boilerplate should be sufficient to achieve MVP and product validation. However, if you're an experienced founder and developing a product for future growth, consider buying a paid option with regular maintenance. Avoid purchasing the most feature-rich starter regardless of community recommendations. Buy the one whose architecture aligns with your requirements. In addition, Supastarter and Kostra receive many mentions in the developer community as the top picks for experienced founders.

Is it worth paying for a Next.js SaaS starter kit?
It depends on your current stage and goals. If you are at the MVP stage and require only validation, there are free starters sufficient enough. If it's your goal to create a profitable product in the coming months, community members consistently advise paying for a starter kit with active maintenance. This recommendation is based on the fact that the time lost debugging outdated dependencies outweighs the price tag of these tools in the first month of development.

What do developers on Reddit recommend for Next.js SaaS starters?
There's consistency in the community advice provided across various r/nextjs and r/SaaS threads. First, when it comes to free options, ixartz/SaaS-Boilerplate remains on top due to its feature richness. When it comes to the paid versions, Supastarter comes up more times than others as a solid choice for complex multi-tenant application. The other advice is to prioritize maintenance instead of the number of stars.

Best Next.js Starter Kit for SaaS in 2026: Free Options, GitHub Repos & Expert Picks

Prince — Thu, 09 Jul 2026 09:25:33 +0000

Most Next.js SaaS starter kit guides focus entirely on authentication and boilerplate structure. This guide goes deeper. In real SaaS products, payments are where production issues usually appear first, and the payment provider you choose affects almost everything: transaction fees, tax compliance, subscription flexibility, and even which starter kits make sense for your business model.

This guide explains the strongest Next.js SaaS starter kits available in 2026, the payment decision many founders underestimate, and the exact process of integrating payments into any Next.js SaaS starter.

What Is the Best Next.js Starter Kit for SaaS in 2026?
There is no universal answer because the best option depends on three factors:

Which payment provider you plan to use
Whether you're building solo or with a team
Whether multi-tenancy is required from the beginning

Best Free Next.js Starter Kits on GitHub
ixartz/SaaS-Boilerplate
Currently, the most feature-rich free Next.js SaaS starter kit that is actively maintained. Includes multi-tenancy with organisation support, RBAC, Clerk authentication (social login, magic links, passkeys, MFA, and user impersonation), Drizzle ORM, Stripe billing, landing page, dashboard, internationalisation, Shadcn UI, Vitest, Playwright, Sentry, and GitHub Actions CI/CD. Already updated for Next.js 16.

One important detail: authentication is powered by Clerk. Clerk has a generous free tier, but once you exceed the monthly active user limits, pricing becomes usage-based. That cost should be considered before fully committing to the stack.

GitHub:
github.com/ixartz/SaaS-Boilerplate

Best for:
Multi-tenant SaaS applications need maximum functionality with no upfront cost.

nextjs/saas-starter
The official minimal SaaS starter is maintained directly by the Vercel and Next.js team. Includes Auth.js v5, Drizzle ORM, PostgreSQL, Stripe billing, Shadcn UI, and Tailwind CSS. It always tracks the newest stable Next.js version.

What it intentionally excludes:
Multi-tenancy, permissions and roles, transactional emails, internationalisation, and testing infrastructure. The project is designed more as a reference implementation than a production-ready SaaS framework.

GitHub:
github.com/nextjs/saas-starter

Best for:
Developers learning modern Next.js SaaS architecture or building heavily customised systems from a lightweight foundation.

PaddleHQ/paddle-nextjs-starter-kit
Paddle's official starter kit for Next.js applications. Designed specifically for SaaS products using Paddle Billing, Supabase, and Vercel. Comes with localized pricing pages, inline checkout flows, and authenticated dashboards with subscription management included.

Notably, this is the only major starter kit officially maintained by a payment company outside the Stripe ecosystem.

GitHub:
github.com/PaddleHQ/paddle-nextjs-starter-kit

Best for:
Teams choosing Paddle instead of Stripe for billing infrastructure.

mickasmt/next-saas-stripe-starter
A clean and thoughtfully organised open-source starter kit. Includes Auth.js v5, Prisma ORM, Neon serverless PostgreSQL, Stripe subscriptions, Resend for transactional email delivery, React Email templates, Shadcn UI, and a role-based admin dashboard.

This sits comfortably between the minimal Vercel starter and the larger ixartz boilerplate. Easier to understand than ixartz while still offering more functionality than the official starter.

GitHub:
github.com/mickasmt/next-saas-stripe-starter

Best for:
Teams wanting a clean architecture without the heavier complexity of enterprise-oriented boilerplates.

boxyhq/saas-starter-kit
An enterprise-oriented free SaaS starter kit. Includes SAML SSO, SCIM directory sync, audit logs, and webhook infrastructure alongside standard SaaS features. Built by a company focused on enterprise identity and security APIs.

GitHub:
github.com/boxyhq/saas-starter-kit

Best for:
Enterprise B2B SaaS platforms requiring compliance and security review readiness.

The Paddle Next.js Starter Kit: An Underrated Option
Most developers default to Stripe automatically. Paddle's official starter kit deserves more attention because Paddle operates under a fundamentally different billing model.

What Paddle's starter includes
The PaddleHQ/paddle-nextjs-starter-kit is a complete, production-ready starter that includes:

The PaddleHQ/paddle-nextjs-starter-kit provides:

Localised pricing pages with multi-currency support

Inline checkout embedded directly into the application

Authenticated billing dashboard

Webhook synchronisation between Paddle and your database

Supabase authentication and database integration

Shadcn UI and Tailwind CSS

One-click Vercel deployment support

What makes Paddle different from Stripe
Paddle acts as a Merchant of Record (MoR). Legally, Paddle becomes the seller of your software products. This means Paddle handles:

VAT collection and remittance

GST compliance

US sales tax collection

Global tax calculations and filings

Instead of managing tax registrations across dozens of jurisdictions, you simply receive payouts from Paddle after taxes are already handled.

Stripe works differently. Stripe is only the payment processor. You remain the legal seller and are responsible for global tax compliance yourself. Stripe Tax can automate calculations, but filing and compliance obligations remain yours.

Paddle's fee structure
Paddle charges 5% + $0.50 per transaction.
Stripe charges 2.9% + $0.30 per transaction, plus 0.5% for Stripe Tax.
Once you add currency conversion, international card fees, and Stripe Billing for subscription management, the effective rate for internationally selling SaaS products is often comparable.

When to choose Paddle's starter kit
Choose Paddle when:

You're selling internationally

Your audience includes consumers or small businesses

You want taxes fully managed

You don't want to deal with VAT registration and remittance

The extra 2–3% cost is usually worth it for small teams and solo founders without dedicated finance or legal resources.

When Stripe makes more sense:

You're building B2B SaaS

Most customers are in a single country

You need deep billing customisation

You require full API flexibility and advanced checkout workflows

Stripe remains stronger for highly customised enterprise billing systems and developer-heavy payment flows.

Stripe vs Lemon Squeezy vs Paddle: Which Should Your Starter Use?

This decision comes before choosing a starter kit. Once you commit to a payment provider, your available starter kit choices become much narrower because most SaaS starters are tightly built around one billing system.

The merchant of record decision
The key distinction is whether you want to operate as the Merchant of Record yourself (Stripe) or use a platform that becomes the Merchant of Record on your behalf (Lemon Squeezy or Paddle).

Stripe: You remain the seller. Customers see your business name on invoices and bank statements, not Stripe's. You keep full ownership of the customer relationship and gain access to one of the most flexible subscription billing systems available.
The trade-off: You are responsible for global tax compliance yourself, either manually or with tools like Stripe Tax.

Lemon Squeezy: Lemon Squeezy acts as the Merchant of Record for your SaaS business. They manage worldwide tax compliance automatically.

Pricing:
5% + $0.50 per transaction.

Advantages:

Very easy setup

Minimal billing configuration

Global tax handling included

VAT/GST management included

Notable detail: Stripe acquired Lemon Squeezy in July 2024, although Lemon Squeezy still operates independently.

Paddle: Paddle also acts as the Merchant of Record and handles:

VAT

GST

US sales tax

International tax remittance

Compared to Lemon Squeezy, Paddle offers stronger enterprise billing features and broader international payment support, including:

KakaoPay

NaverPay

WeChat Pay

Pix

Advanced subscription management

Which starter kits support each provider
Stripe: ixartz SaaS Boilerplate, nextjs/saas-starter, mickasmt/next-saas-stripe-starter, boxyhq/saas-starter-kit, Kostra, ShipFast (default), MakerKit (primary option)

Lemon Squeezy: Supastarter supports both Stripe and Lemon Squeezy. Some MakerKit tiers support Lemon Squeezy.

Paddle: PaddleHQ/paddle-nextjs-starter-kit (official), and some commercial kits like Supastarter add Paddle as an option.

The practical decision for most founders
Solo founder, global consumer SaaS: Lemon Squeezy or Paddle. Tax compliance handled for you. Worth the extra 2%.

B2B SaaS, customers primarily US/EU: Stripe. More control, lower fees at scale, better subscription management for complex B2B billing.

Large global product, enterprise features needed: Paddle. Better international payment method support than Lemon Squeezy, more enterprise-focused.

How to Add Payments to a Next.js SaaS Starter
If your chosen starter doesn't include payments, or you need to swap the payment provider, here's how to add each option.

Adding Stripe
Install the Stripe SDK:

npm install stripe @stripe/stripe-js
Add your keys to .env.local:

STRIPE_SECRET_KEY=sk_test_...
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...
Create a checkout session in a Server Action:

// app/actions/billing.ts
'use server'
import Stripe from 'stripe'

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!)
export async function createCheckoutSession(priceId: string, userId: string) {
const session = await stripe.checkout.sessions.create({
payment_method_types: ['card'],
mode: 'subscription',
line_items: [{ price: priceId, quantity: 1 }],
success_url: ${process.env.NEXT_PUBLIC_APP_URL}/dashboard?success=true,
cancel_url: ${process.env.NEXT_PUBLIC_APP_URL}/pricing,
metadata: { userId },
})
return { url: session.url }
}
Create a webhook handler to keep your database in sync:

// app/api/stripe/webhook/route.ts
import Stripe from 'stripe'
import { headers } from 'next/headers'
const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!)
export async function POST(req: Request) {
const body = await req.text()
const signature = (await headers()).get('stripe-signature')!
let event: Stripe.Event
try {
event = stripe.webhooks.constructEvent(
body,
signature,
process.env.STRIPE_WEBHOOK_SECRET!
)
} catch {
return new Response('Invalid signature', { status: 400 })
}
switch (event.type) {
case 'customer.subscription.created':
case 'customer.subscription.updated':
// Update subscription status in your database
break
case 'customer.subscription.deleted':
// Remove subscription access in your database
break
}
return new Response(null, { status: 200 })
}
Test webhooks locally:

stripe listen --forward-to localhost:3000/api/stripe/webhook

Adding Paddle
Install the Paddle.js SDK:

npm install @paddle/paddle-js
Add your Paddle keys to .env.local:

NEXT_PUBLIC_PADDLE_CLIENT_TOKEN=test_...
PADDLE_API_KEY=pdl_...
PADDLE_NOTIFICATION_WEBHOOK_SECRET=...
NEXT_PUBLIC_PADDLE_ENV=sandbox
Initialize Paddle in your layout:

// app/providers.tsx
'use client'
import { initializePaddle, Paddle } from '@paddle/paddle-js'
import { useEffect, useState } from 'react'
export function PaddleProvider({ children }: { children: React.ReactNode }) {
const [paddle, setPaddle] = useState()
useEffect(() => {
initializePaddle({
environment: process.env.NEXT_PUBLIC_PADDLE_ENV as 'sandbox' | 'production',
token: process.env.NEXT_PUBLIC_PADDLE_CLIENT_TOKEN!,
}).then(paddleInstance => setPaddle(paddleInstance))
}, [])
return (
// Pass paddle instance to context if needed
<>{children}</>
)
}
Open a checkout:

paddle?.Checkout.open({
items: [{ priceId: 'pri_your_price_id', quantity: 1 }],
})
Create a webhook handler to sync subscription state:

// app/api/webhook/route.ts
import { EventName } from '@paddle/paddle-node-sdk'
export async function POST(req: Request) {

const signature = req.headers.get('paddle-signature')!
const rawBody = await req.text()
// Verify signature
// Process event.eventType
// Update database accordingly
return new Response(null, { status: 200 })

}
The Paddle starter kit (PaddleHQ/paddle-nextjs-starter-kit) has all of this pre-configured. Cloning it is faster than implementing from scratch.

Adding Lemon Squeezy
npm install @lemonsqueezy/lemonsqueezy.js

LEMONSQUEEZY_API_KEY=...
LEMONSQUEEZY_STORE_ID=...
LEMONSQUEEZY_WEBHOOK_SECRET=...

Lemon Squeezy uses a hosted checkout URL rather than an inline checkout. You redirect users to checkoutUrl returned from the API to complete payment.

import { createCheckout } from '@lemonsqueezy/lemonsqueezy.js'
const checkout = await createCheckout(storeId, variantId, {
checkoutOptions: { embed: false },
checkoutData: { email: userEmail },
productOptions: {
redirectUrl: ${process.env.NEXT_PUBLIC_APP_URL}/dashboard,
},
})
redirect(checkout.data?.data.attributes.url)

How to Set Up a Next.js Starter Kit with Auth, Database, and Stripe
Full setup flow from clone to running locally, using the ixartz SaaS Boilerplate as the example.

Step 1: Clone without Git history
npx degit ixartz/SaaS-Boilerplate my-saas
cd my-saas
npm install
cp .env.example .env.local

Step 2: Configure your database
The ixartz boilerplate uses Drizzle ORM. Create a free PostgreSQL database on Neon (neon.tech), then add the connection string:

DATABASE_URL=postgres://user:pass@host/dbname?sslmode=require

Run migrations:

npm run db:migrate

Step 3: Set up Clerk auth
Create a Clerk application at clerk.com. Add the keys to .env.local:

NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_...
CLERK_SECRET_KEY=sk_test_...
NEXT_PUBLIC_CLERK_SIGN_IN_URL=/sign-in
NEXT_PUBLIC_CLERK_SIGN_UP_URL=/sign-up
NEXT_PUBLIC_CLERK_AFTER_SIGN_IN_URL=/dashboard
NEXT_PUBLIC_CLERK_AFTER_SIGN_UP_URL=/onboarding
Enable the OAuth providers you want (Google, GitHub) in the Clerk dashboard under Social Connections.

Step 4: Set up Stripe
Create a Stripe account. In test mode, create your products and pricing tiers. Add the keys:

STRIPE_SECRET_KEY=sk_test_...
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...

Update the pricing tiers in the boilerplate to match your Stripe price IDs.

Step 5: Configure email
The ixartz boilerplate uses Sentry for error monitoring but doesn't include email by default. Add Resend for transactional email:

npm install resend

RESEND_API_KEY=re_...

Step 6: Run locally and test
npm run dev

In a separate terminal, start the Stripe webhook forwarding:

stripe listen --forward-to localhost:3000/api/stripe/webhook
Test the full flow: sign up, create an organization, upgrade to a paid plan using test card 4242 4242 4242 4242. Check your database to verify subscription status updated correctly.

Step 7: Deploy
Push to GitHub. Connect to Vercel. Add all production environment variables. Create a production Stripe webhook pointing to https://yourdomain.com/api/stripe/webhook. Switch Stripe keys from test to live.

Which Next.js Starter Kit Is Best for Solo Founders?
There are specific priorities that solo founders have versus teams: speed to launch over architecture, documentation over flexibility, and cost over feature completeness.

Free option for solo founders: ixartz SaaS Boilerplate

Feature complete, well-maintained, and free. Drawback: setup process takes more time. ixartz boilerplate does more than most paid starters but takes some configuring. Expect to allocate half a day to go through the boilerplate code and configure all services.

Paid option for solo founders: ShipFast

Best known for its ability to give you a quick SaaS launch out of the box. Everything is well-documented. Discord community is large and engaged. Consistently, developers claim they can launch their SaaS, with user authentication and payment, within a day after buying. Drawback: opinionated stack, which means it's hard to deviate from. It relies heavily on Clerk + Stripe + a specific folder structure.

For global consumer SaaS specifically: Paddle starter kit

If you're selling your product internationally and don't want to think about taxes, use Paddle Next.js starter kit. Officially supported by Paddle and free, it will save you the headache of figuring out global tax compliance once you start seeing orders from other countries.

What nobody dares to ask the solo founder about explicitly:

How much time you have?
If you can spend at least a couple of days setting up your SaaS framework, use ixartz for free. Otherwise, if you need to write product features the next day, a paid starter like ShipFast pays itself off after the first afternoon.

Downloading and Setting Up a Next.js Starter Kit
Method 1: degit (recommended)
npx degit username/repo my-project
cd my-project
npm install
degit clones without Git history. You get clean project ownership from day one without the original repo's commit history.

Method 2: GitHub template
Many starter repos have a "Use this template" button on GitHub. This creates a new repo in your GitHub account forked from the starter. Good if you want the initial commit history and a linked GitHub repo immediately.

Method 3: npx create commands
Some starters offer a create command:

npx create-next-app@latest --example "https://github.com/nextjs/saas-starter"
After cloning: the mandatory first steps
Before you start coding your actual product, remember to perform these actions:

Read the README completely. Understand what's included before you start. Most setup problems come from skipping steps described in the documentation.

Copy .env.example to .env.local and fill in all values. Most starters won't run at all without their required environment variables. All of them are documented in .env.example with explanations.

Check the Next.js version. To do this, open package.json of the starter. If Next.js version number is less than 15.x, this means you're working with an outdated version. If it is less than 16.x - it dates back to times before major changes in 2025年年底前.

FAQs
Where can I find Next.js starter kit repos on GitHub?
There is one topic specifically created for Next.js starters - nextjs-saas. Other popular searches include nextjs saas starter kit, saas boilerplate nextjs, or nextjs starter template. Use sorting by Most Stars to filter for quality and inspect the last commit date. Repos to consider: ixartz/SaaS-Boilerplate, nextjs/saas-starter, PaddleHQ/paddle-nextjs-starter-kit, boxyhq/saas-starter-kit.

How do I download a Next.js starter kit?
Clone it with npx degit username/repo my-project to get a fresh codebase with no Git history, or git clone https://github.com/username/repo to make a full clone with history included. After that, use npm install, copy the env variables in .env.example to .env.local, fill up values and run npm run dev.

What is the best Next.js starter template?
There isn't a single "best" Next.js starter template. For regular projects, try ixartz/Next-js-Boilerplate (free, supports the latest Next.js 16). If you need multi-tenancy in your SaaS, check out ixartz/SaaS-Boilerplate (free) and Kostra (paid, used in production by bigger companies). To use Paddle Billing, there is PaddleHQ/paddle-nextjs-starter-kit (free, official).

Are there free Next.js templates available?
Absolutely! Here are the strongest free options: nextjs/saas-starter (official and minimal), ixartz/SaaS-Boilerplate (most features), PaddleHQ/paddle-nextjs-starter-kit (integrates with Paddle), boxyhq/saas-starter-kit (enterprise), mickasmt/next-saas-stripe-starter (minimal but clean). These repos are all free to use and licensed under a permissive open-source license.

What is the Paddle Next.js starter kit?
The PaddleHQ/paddle-nextjs-starter-kit is an official starter kit for Next.js developed and supported by Paddle. It provides a comprehensive base for creating SaaS products using Paddle billing (not Stripe), Supabase for auth and backend database, and Vercel for hosting your app. Includes landing page with pricing, inline checkout, authenticated user dashboard, and webhooks handler. Paddle Billing is the Merchant of Record and takes care of global tax compliance for you. The starter is completely free and available both on GitHub and deployed via the Vercel templates library.

What is the best Next.js starter kit overall in 2026?
It really depends on your payment provider and the number of developers. If you are a solo founder or have a small team and need the most feature-rich option for free, use ixartz SaaS Boilerplate. If you want only a minimal starter template from the Next.js team, then try nextjs/saas-starter. For projects working with Paddle, their official starter kit should work just fine. Finally, Kostra will be the best choice for a paid production-ready solution. What people mean when saying SaaS starter kit from "Bulletproof Next.js" developers is ixartz SaaS Boilerplate.

What is the best Next.js starter kit in 2025 and 2026?
Quite a difference there between those two years. Next.js 16 was released in October 2025 and introduced major changes, such as replacing the middleware.ts file with proxy.ts and using Turbopack by default. At the same time, Tailwind CSS v4 became stable and deprecated its JavaScript config file. Next.js starter kits that have not been updated are now using outdated configurations.

Here are the actively maintained and kept-up-to-date options for the Next.js starter kit in 2026: ixartz SaaS Boilerplate (free, uses the latest Next.js 16 and Tailwind v4), Blazity/next-enterprise (free and enterprise-grade), nextjs/saas-starter (always current), Kostra (actively maintained and paid). Check the last commit date and the Next.js version in the package.json of the starter before using it.

Next.js SaaS Starter Kits: GitHub's Best Repos to Kickstart Your SaaS in 2026

Prince — Thu, 09 Jul 2026 09:22:02 +0000

You've decided to build a SaaS product. You're using Next.js. Now, the decision of whether to use a starter kit has already been made for you. The question is which kit you're going to choose and how relevant it is to opt for a free open-source solution over a paid one.

This guide will help you navigate the world of Next.js SaaS starters available in 2026, learn how to set up one of them with Stripe and Supabase, learn how to integrate authentication, and discover why paid SaaS starter kits aren't really used despite free alternatives being around.

What Makes a Good Next.js SaaS Starter in 2026?
First and foremost, let's define our expectations. There are many repositories claiming to be SaaS starter kits, while essentially being just landing page templates with an account creation/login form. A proper starter for SaaS applications in 2026 must meet some non-negotiable criteria.

Non-negotiable features:
App Router support.
The Pages Router is legacy. Any starter that hasn't switched to App Router yet will require migration, making it non-future proof.

Types everywhere.
If a starter has only JavaScript and not TypeScript, this is a sign of low maintenance standards. Type safety is essential and shouldn't be compromised.

Auth system including social logins.
At a bare minimum, an email/password method plus Google/Github OAuth authentication.

Stripe with subscription processing.
A payment processor is mandatory. Most starter kits provide Stripe as the example but lack the most important piece of the puzzle – a webhook handler.

Regular updates.
If the latest commit date of a repository is older than three months, the starter is likely to be incompatible with recent versions of Next.js and its ecosystem due to frequent changes in these.

2026-specific requirements:
Next.js 16 support with proxy.ts (not the deprecated middleware.ts).

Tailwind CSS v4 configuration using @import "tailwindcss" and @theme in CSS rather than a JavaScript config file.

These two alone filter out a significant portion of starters that haven't been updated.

What separates good from great:
Multi-tenancy built into the data model. Logging and error monitoring (Sentry or similar). A test suite. Clear documentation that explains architectural decisions, not just setup steps.

Best Open-Source Next.js SaaS Starters on GitHub

nextjs/saas-starter (Official Vercel Starter) An official starter from the very creators of Next.js. Maintained by the same people, it's minimalist, correct, and stays up to date with the framework.

What it includes:

Next.js App Router

Auth.js (v5+) for authentication

Drizzle ORM

Stripe subscriptions with webhook handler

Shadcn UI components

Tailwind CSS

A working landing page and dashboard.

What it doesn't include:

Support for multi-tenancy

Roles and permissions

Transactional emails

Internationalization (i18n)

Test coverage

It's intentionally kept minimal for educational purposes. Vercel's goal with this starter is to demonstrate the correct architecture for SaaS apps rather than giving all the bells and whistles.

Stack: Next.js 15/16, TypeScript, Tailwind CSS, Drizzle ORM, Auth.js v5, Stripe, Shadcn UI
GitHub: https://vercel.com/templates/next.js/auth0-nextjs-saas-starter

Best for: Developers who want to understand the correct patterns for a SaaS setup without inheriting someone else's feature decisions.

ixartz/SaaS-Boilerplate The most comprehensive free Next.js SaaS starter out there, offering way more than the official option.

What it includes:

Multi-tenancy and team support with organization switching

RBAC with owner/admin/member roles

Authentication with Clerk – social authentication, magic links, passwordless with passkeys and multi-factor auth, and user impersonation

Drizzle ORM compatible with PostgreSQL/SQLite/MySQL

Stripe subscriptions with webhook processing

A functional landing page

User dashboard

i18n with Crowdin

Shadcn UI

ESLint

Prettier

Vitest

Playwright

GitHub Actions

Sentry error monitoring, and the

Bundle Analyzer.

Notable detail: This starter kit uses passkeys for passwordless login which is uncommon among free starters. Multi-factor authentication and user impersonation in a free repo is quite rare too, but can prove helpful for debugging later.

Stack: Next.js 16, TypeScript, Tailwind CSS, Shadcn UI, Clerk, Drizzle ORM, Stripe

GitHub: github.com/ixartz/SaaS-Boilerplate

Best for: Teams building multi-tenant SaaS products who want the most complete free foundation.

mickasmt/next-saas-stripe-starter Another well-structured Next.js starter. Not the most feature-rich but offers an excellent clean codebase that is easy to modify later.

What it includes:

Auth.js v5 with Google/GitHub/email providers

Prisma ORM with Neon serverless Postgres

Stripe subscriptions with webhook processing

Resend for transactional email delivery

React Email library

Shadcn UI components

Admin dashboard with user roles management

Honest take: A nice starter sitting between the official starter and the ixartz one – more complete than the official starter, less opinionated than the ixartz one.

Stack: Next.js, TypeScript, Tailwind CSS, Shadcn UI, Auth.js v5, Prisma, Neon, Stripe, Resend

GitHub: github.com/mickasmt/next-saas-stripe-starter

boxyhq/saas-starter-kit If you are targeting larger companies as clients, this is the only starter with built-in enterprise-level functionality included. This is also the most complex starter out there.

What it includes:

Team management system

SAML SSO support provided by Jackson library

Directory synchronization provided by SCIM connector

Audit logging provided by Retraced

Webhook management

Stripe subscriptions with webhook processing

Prisma ORM with PostgreSQL

Honest take: If your application targets enterprises, there's no other starter that would give you all this out of the box for free. For consumer SaaS or SaaS for small businesses, however, all the enterprise-level features are overhead.

Stack: Next.js, TypeScript, Tailwind CSS, Prisma, PostgreSQL, Stripe

GitHub: github.com/boxyhq/saas-starter-kit

Best for: Enterprise B2B SaaS with SAML SSO and compliance requirements.

KolbySisk/next-supabase-stripe-starter A structured starter built for Supabase and Stripe stack. Supabase is gaining popularity because of its ease of use, scalability, and serverless nature.

What it includes:

Supabase authentication

Postgres via Supabase

Stripe subscriptions with webhook processing that syncs subscription state in Supabase database

Resend for transactional email

Shadcn UI

Feature-based project structure

Notable detail: Supabase Stripe Fixtures. Unlike regular setups where products and prices are set manually in the Stripe console, with Supabase you can configure them programmatically in the JSON file and apply using Stripe CLI command.

Stack: Next.js, TypeScript, Tailwind CSS, Shadcn UI, Supabase Auth, PostgreSQL, Stripe, Resend

GitHub: github.com/KolbySisk/next-supabase-stripe-starter

Best for: Teams committed to the Supabase stack who want a clean, well-organized starting point.

GitHub: github.com/NextJSTemplates/play-nextjs
Best for: Startups that want a polished starting point without paying for a premium kit.

SaaS Starter Kit by Bulletproof Next.js
This phrase pops up in Google searches for SaaS starter kits occasionally. It refers to the ixartz boilerplate which implements the opinionated architecture based on patterns described in "Bulletproof React".

"Bullertproof Next.js" doesn't mean anything official here. The phrase stands for an opinionated, robust approach which implies strict TypeScript usage, feature-based folders structure, clear separation of server and client code, multiple levels of testing, and CI/CD pipeline right away.

"SaaS starter kit by Bulletproof Next.js" will lead you to this GitHub repository: github.com/ixartz/SaaS-Boilerplate.

How to Set Up a Next.js SaaS Starter with Stripe and Supabase
Here's a step-by-step process of setting up a SaaS app with Supabase and Stripe using any starter kit.

Step 1: Clone your starter
npx degit KolbySisk/next-supabase-stripe-starter my-saas

cd my-saas

npm install

cp .env.example .env.local

Step 2: Create your Supabase project
Go to supabase.com. Create a new project. Note down:

Your Supabase project URL (NEXT_PUBLIC_SUPABASE_URL)

Your anon/publishable key (NEXT_PUBLIC_SUPABASE_ANON_KEY)

Your service role key (SUPABASE_SERVICE_ROLE_KEY)

Add these to your .env.local file.

Step 3: Run the database migrations
Most Supabase-based starters include migration files. Run them through the Supabase SQL Editor or with the Supabase CLI:

supabase db push

This creates the users, subscriptions, and any other tables the starter requires.

Step 4: Create your Stripe products
You have two options: configure products manually in the Stripe dashboard, or use Stripe Fixtures if your starter supports them.

With Stripe Fixtures:

stripe fixtures ./stripe-fixtures.json --api-key sk_test_YOUR_KEY

Add your Stripe keys to .env.local:

STRIPE_SECRET_KEY=sk_test_...

NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_test_...

STRIPE_WEBHOOK_SECRET=whsec_...

Step 5: Set up Stripe webhooks locally
stripe listen --forward-to localhost:3000/api/stripe/webhook

This forwards Stripe events to your local server. The webhook handler in the starter should process events like checkout.session.completed and customer.subscription.updated, updating your Supabase database when a subscription state changes.

Step 6: Configure Supabase Auth providers
In your Supabase dashboard, go to Authentication → Providers. Enable Google and GitHub OAuth. Get your client ID and secret from each provider's developer console and add them to Supabase.

For Google OAuth, you need a project in Google Cloud Console with the OAuth consent screen configured and credentials created.

Step 7: Run the project locally
npm run dev

Open http://localhost:3000. The signup, login, and Stripe checkout flows should work end-to-end in test mode.

Step 8: Deploy to Vercel
Push to GitHub. Connect to Vercel. Set your production environment variables. Create a production Stripe webhook pointing to https://your-domain.com/api/stripe/webhook and select the events you need.

Switch your Stripe keys from test (sk_test_) to live (sk_live_) when you're ready to accept real payments.

How to Add Authentication to a Next.js SaaS Starter
If your starter doesn't include authentication or you need to add a provider, here's how to approach it.

Option 1: Auth.js (self-hosted)
Auth.js v5 is the standard for self-hosted authentication in Next.js. Your user data stays in your database.

npm install next-auth@beta

Create auth.ts at your project root:

import NextAuth from 'next-auth'

import GitHub from 'next-auth/providers/github'

import Google from 'next-auth/providers/google'

export const { handlers, auth, signIn, signOut } = NextAuth({

providers: [GitHub, Google],

})

Create app/api/auth/[...nextauth]/route.ts:

import { handlers } from '@/auth'

export const { GET, POST } = handlers

Protect routes in proxy.ts (Next.js 16) or middleware.ts (Next.js 15):

export { auth as proxy } from '@/auth'

export const config = {

matcher: ['/dashboard/:path*', '/settings/:path*'],

}

Add your OAuth app credentials to .env.local:

AUTH_GITHUB_ID=your_github_client_id

AUTH_GITHUB_SECRET=your_github_client_secret

AUTH_GOOGLE_ID=your_google_client_id

AUTH_GOOGLE_SECRET=your_google_client_secret

AUTH_SECRET=your_random_secret_string

Option 2: Clerk (hosted)
Clerk handles the entire auth lifecycle: user management, MFA, device sessions, and a pre-built UI. Easier to configure than Auth.js but your user data is on Clerk's servers.

npm install @clerk/nextjs

Wrap your root layout:

import { ClerkProvider } from '@clerk/nextjs'

export default function RootLayout({ children }) {

return (

<ClerkProvider>

  <html>

    <body>{children}</body>

  </html>

</ClerkProvider>

)

}

Protect routes in proxy.ts:

import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server'

const isProtectedRoute = createRouteMatcher(['/dashboard(.)', '/settings(.)'])

export default clerkMiddleware(async (auth, req) => {

if (isProtectedRoute(req)) await auth.protect()

})

Option 3: Supabase Auth
If your starter already uses Supabase for the database, Supabase Auth is a natural choice. It avoids adding another service.

npm install @supabase/supabase-js @supabase/ssr

Supabase Auth handles email/password, magic links, and OAuth providers. The @supabase/ssr package is the current standard for Next.js App Router integration, replacing the older auth helpers package.

Which auth option should you choose?
Auth.js – if you want full ownership of your users and data with no per user fees.

Clerk – if you want maximum functionality with minimum configuration.

Supabase Auth – if you're already using Supabase for your database.

BoxyhQ SAML Jackson or a dedicated identity provider – if you need SAML-based single sign-on for your enterprise customers.

Can You Use a Next.js SaaS Starter for Free?
Yes. In fact, there are several production-ready free options.

The list below includes free to clone, use, and deploy options without licensing costs.

nextjs/saas-starter (official Vercel starter)

ixartz/SaaS-Boilerplate (most feature-complete free option)

mickasmt/next-saas-stripe-starter (clean mid-range option)

boxyhq/saas-starter-kit (enterprise compliance focus)

KolbySisk/next-supabase-stripe-starter (Supabase + Stripe stack)

NextJSTemplates/play-nextjs (design-quality focus)

All projects in the list above are released under a permissive license like the MIT License. No royalties, no revenue sharing, and no mandatory attribution in the product. All code you write yourself, all code you use, all code in your project belongs to you.

Real cost of free solutions:

The code is free. Time isn't. Free projects typically take more time to set up, require more decisions, and will need debugging that is harder to solve without experience. Even a paid starter's price is quickly covered by saved developer hours with any reasonable developer hourly rate.

Maintained projects in the list above have been committed to regularly by their creators. Some other popular free Next.js SaaS starters are not updated. It's not really free if your solution runs some outdated security patches.

Are People Actually Buying Next.js Starters?
Yes, in significant numbers. The Next.js SaaS starter market has been estimated at $50M+ in annual revenue as of 2026. ShipFast alone has sold to tens of thousands of developers. Supastarter, MakerKit, and similar products have substantial customer bases.

The developer community's answer to "are people actually buying this?" is: yes, and the reasons are consistent.

Why developers buy starters:

First, time savings are real and quantified. Developers who had used both approaches reported saving 100 to 200 hours setting up the project on average. At any reasonable developer hourly rate, a paid starter is worth it.

Documentation. Documentation in paid starters explains architectural decisions, upgrade procedures, edge cases, etc. Free starters typically include README files. Quality is different.

Support. Paid projects include access to Discord communities or support forums where developers can ask questions about production problems. GitHub is the closest thing free starters offer in the area.

Active maintenance guarantee. Paid projects are commercial software. There is a monetary incentive to keep up with updates. Free projects need commitment from their creators.

The honest counterargument:

Paid solutions don't always live up to their expectations. Users sometimes buy a starter but find out they wasted money because the starter is based on assumptions that aren't true for their specific case.

Mitigation: almost all paid projects have a demo version. Carefully read the documentation before purchasing.

The community consensus:

Founders who want to build a product they will scale in the future should definitely opt for paid starter. Developers working on MVPs or exploring the Next.js ecosystem will do fine with a free starter. Enterprises definitely should use paid starter with ongoing support.

What Is the Best Free Next.js SaaS Starter?
Directly: ixartz/SaaS-Boilerplate is the best free Next.js SaaS starter available in 2026.

Feature completeness. ixartz/SaaS-Boilerplate includes multi-tenancy, roles-based access control, Clerk authentication with passkeys and multi-factor authorization, Stripe billing, localization, Shadcn ui components, testing, continuous integration, error monitoring, and more. All of that in one free repository.

Drawbacks? One only: complexity. There's quite a lot to know to understand how it works. If you find it too complicated, go with the official Next.js SaaS starter. Then upgrade when you need more features.

Specific suggestions for the Supabase ecosystem: KolbySisk/next-supabase-stripe-starter

Specific suggestion for enterprise compliance requirement: boxyhq/saas-starter-kit (only free option providing SAML single-sign-on and audit logs)

When Free Isn't Enough: Paid Options Worth Considering
Free open-source Next.js SaaS starters serve well as foundations. There are three cases when the gap between paid and free gets problematic.

Maintenance. Free starters rely on a maintainer's availability. When Next.js releases new major, paid starter gets an update automatically. Free starters need time to update.

Documentation. Paid starters have better quality documentation. More architectural decisions explained, more upgrade guides, more security considerations, etc.

Access to paid support channels. When something crashes in your production environment in the middle of the night, having access to a dedicated Discord channel is very useful.
