Supastarter Explained: Build Your Next.js SaaS Faster

Every Next.js SaaS starter kit begins the same way: a sharp idea, a free weekend, and a blank folder. By Sunday night you have a login page that sort of works, a half-finished Stripe webhook, and a growing list of things you still need. Password reset. Team invites. Email templates. A pricing page. An admin panel.

None of that is your product. It is the plumbing every SaaS needs before a customer can use the one feature that matters.

That is the problem a Next.js SaaS starter kit solves, and supastarter is one of the more complete options. This guide covers what is inside, what it costs, where it falls short, and how to go from purchase to a running app.

What supastarter actually gives you

supastarter is a fullstack SaaS boilerplate built by Jonathan Wilke. You buy it once, get access to a private repository, and build your product on top of that code. It is not a hosted service and it does not add a runtime dependency to your app.

The Next.js version uses the App Router and React Server Components. It ships as a Turborepo monorepo with separate apps for the marketing site, the product, the documentation, and email previews.

The commercial license allows unlimited projects. That matters if you run an agency or build several small products, because you are not buying one app. You are buying a foundation you can reuse.

The catch is the usual one with starter kits. You inherit someone else's architecture. better-auth, Hono, oRPC, Prisma or Drizzle, and a specific folder layout are already chosen. If those choices match how you like to build, you save weeks. If you want a different stack, you will spend that time swapping parts.

What the Next.js SaaS starter kit includes

The docs list a broad feature set. A few areas deserve a closer look before you pay.

Area	What you get
Marketing site	Landing page, pricing, MDX blog with i18n, changelog, contact form, legal pages and SEO metadata
Authentication	better-auth with email and password, passkeys, magic links, OAuth, 2FA, password reset and email verification
Organizations	Teams, invites, owner and member roles, organization settings and data isolation
Payments	Stripe, Lemon Squeezy, Creem, Polar and Dodo Payments, with subscriptions, one-time plans, webhooks and a billing portal
Database	Prisma or Drizzle ORM, PostgreSQL by default, plus guides for Neon, Supabase, PlanetScale, Turso and Railway
API layer	Hono with oRPC, TanStack Query and generated OpenAPI documentation
Storage	S3-compatible storage, including AWS S3, Cloudflare R2, DigitalOcean Spaces, SeaweedFS, MinIO and Supabase Storage
Email	React Email with Tailwind styling, plus Resend, Postmark and Nodemailer providers
AI	Vercel AI SDK integration, a chatbot with history, and text, image and audio model support
Background jobs	trigger.dev, Upstash QStash and BullMQ
Deployment	Guides for Vercel, Render, Fly.io, Netlify, Docker, Coolify and Railway

The monorepo split is worth understanding because it shapes where you work:

App	Purpose
apps/marketing	Public site, blog, changelog, legal pages and sitemap
apps/saas	Authentication, onboarding, organizations, billing, admin and API routes
apps/docs	Documentation site
apps/mail-preview	Email previews during development

Keeping the marketing site separate from the product is a sensible default. The public pages can cache and deploy on their own schedule, while the authenticated app stays focused.

The authentication story has improved since the early versions. better-auth now covers passkeys and two-factor authentication in addition to the usual password and OAuth flows. The organization model is also ready on day one, which is the part most teams underestimate. Adding teams and data isolation after you have paying customers is much harder than starting with them.

On the API side, Hono and oRPC give you typed endpoints and a typed client. If you have used tRPC, the idea will feel familiar. The difference is that oRPC is built around OpenAPI, so you also get a generated API description you can inspect or share.

What it costs in November 2026

The official pricing page lists three one-time plans. There is no subscription.

Plan	Price	Seats	What stands out
Solo	$349	1 developer	Unlimited personal projects, commercial use, lifetime updates
Startup	$799	5 developers	Priority support and a 60-minute consulting call
Agency	$1,499	10 developers	White-label use, client projects, private Discord access and a consulting call

Prices change, and the site was running a promotion at the time of writing. Treat the table as a snapshot, not a quote. Check the current pricing before you decide.

A fair way to judge the price is to compare it with your own time. If auth, teams, billing and email would take you three weeks, the Solo plan is cheap. If you are building a single-user tool with one login method, it is more than you need.

Where it fits, and where it does not

supastarter makes the most sense for multi-tenant B2B products. The organizations, roles, invites and billing pieces are already connected, and those are the parts that usually turn a two-week MVP into a two-month project.

It also fits indie developers who want to launch several products without rebuilding the same foundation each time. The unlimited-projects license is the reason.

It fits less well in three cases.

First, a tiny internal tool. You will spend more time deleting unused modules than building.

Second, a team with strong opinions about auth, API design or database access. You can replace any part, but the value comes from keeping the defaults.

Third, a product that needs a stack the kit does not support. Confirm the framework before you buy, because the marketing site, docs and pricing selector have not always listed the same set.

We have not shipped a production app on supastarter ourselves. This guide follows the official documentation and pricing page, and the judgment calls are ours. That is worth saying plainly, because a starter kit review is easy to turn into a sales page.

How to go from purchase to a running app

The official setup guide is the source of truth. Commands and file locations change between releases, so keep the supastarter documentation open while you work.

Prerequisites

You need Node.js 20 or newer, Git, pnpm, a code editor, and a database connection string. PostgreSQL is the default, and the docs also cover MySQL and SQLite.

1. Create the project

After purchase you get access to the private repository. The quickest start is the CLI:

npx supastarter new my-awesome-project

The command clones the repository, asks for your database details, installs dependencies and sets up the database. If it fails, the manual path is to clone the repository and run pnpm install, then copy .env.local.example to .env.local and fill in DATABASE_URL.

Never commit that file. If you have not enabled secret scanning yet, our guide to GitHub security setup shows how to catch a leaked key before it reaches a public repo. Your payment and email keys will live in the same file.

2. Pick your ORM and database

Prisma is the default in the setup docs. Drizzle is supported through a different export in packages/database/index.ts and an adapter change in packages/auth/auth.ts.

Choose one before you write models. Switching later is possible, but it touches your schema, your auth adapter and every query in between.

The database provider matters less. PostgreSQL is the safest default, and the docs include provider guides for Neon, Supabase, PlanetScale, Turso and Railway.

3. Configure email

Pick a mail provider by changing the export in packages/mail/provider/index.ts. Resend needs RESEND_API_KEY. Postmark needs POSTMARK_SERVER_TOKEN. Nodemailer needs the host, port and credentials.

For local work, the console provider prints emails to your terminal instead of sending them. The mail preview app lets you edit templates without triggering a real signup.

4. Connect a payment provider

Choose one of the five supported providers and export it in the payments module. Create your products and plans in the provider dashboard, then add the keys and plan IDs to your environment and plan configuration.

If global tax compliance is a concern, start with one of the merchants of record, such as Creem or Lemon Squeezy. If you want the most familiar developer experience, Stripe is still the default choice for most teams.

Test the full lifecycle in sandbox mode before launch: signup, upgrade, downgrade, cancellation and a failed payment. A broken webhook is the kind of bug that costs real money.

5. Push the schema and start the app

pnpm --filter database push
pnpm --filter database generate
pnpm --filter scripts create:user
pnpm dev

The exact scripts can differ if you use Drizzle, so check the database docs for your path. pnpm dev can start several apps at once, including the marketing site, the SaaS app and the docs.

6. Customize the marketing site

Edit the landing page, pricing page and blog in apps/marketing. Replace the sample copy with your own message. Keep the SEO basics tight, and do not ship a generic template with your logo pasted on top. Our guide to removing AI slop from website design covers the visual side, and the Hugo SEO guide is useful even if you are not using Hugo.

7. Build the feature that makes you different

Work inside apps/saas. A few habits will keep the codebase manageable:

• Scope every new table by organization so tenant data stays separate.
• Add endpoints through Hono and oRPC, then call them with TanStack Query.
• Gate paid features with the paywall components instead of scattering plan checks through the UI.
• Follow the feedback widget recipe in the docs. It walks from database to UI and is a good template for your first feature.

Here is a small Prisma model that follows the multi-tenant pattern:

model Project {
  id             String   @id @default(cuid())
  name           String
  organizationId String
  createdAt      DateTime @default(now())

  @@index([organizationId])
}

Adapt the field names to the conventions already in the repo. The important part is the organization index. It keeps tenant queries from scanning every row as you grow.

8. Deploy and keep up with updates

Run the included Playwright tests where they apply, then deploy. The docs cover Vercel, Render, Fly.io, Netlify, Docker, Coolify and Railway. If you use a custom domain behind Cloudflare, our GitHub Pages and Cloudflare guide explains the DNS side, and the same ideas apply to most hosts.

Before your first release, set the supastarter repository as an upstream remote. That is how you pull fixes and new features later. Commit small changes, keep customizations in clearly separated files, and read the changelog before merging a large update.

How it compares with other starter kits

Kit	Starting price	Stack highlights	Best fit
supastarter	$349	Next.js, Nuxt and other framework codebases, better-auth, Prisma or Drizzle, Hono, five payment providers	Multi-tenant B2B SaaS and teams that want a broad foundation
ShipFast	$199	Next.js, MongoDB or Supabase, Stripe, Google OAuth	Solo founders who want a lean start
MakerKit	$349	Next.js with Supabase, Drizzle or Prisma variants	Teams that want a kit per database choice
TurboStarter	$179	Web, mobile and browser extension in one repo	Products that need several surfaces

Prices come from public pages and can change. The useful question is not which kit has the most features. It is which kit matches the parts you do not want to build.

If you are still deciding whether to use a kit at all, our comparison of vibe coding and vibe engineering looks at the trade-off between speed and understanding. A starter kit tilts the balance toward speed, and you still need to understand the code you ship.

If you want to stress-test the launch before real users arrive, our walkthrough on setting up and testing a SaaS launch covers the rehearsal. If referrals are part of your growth plan, the guide to affiliate software for SaaS explains the moving parts.

One more option deserves a mention. If your product is mostly AI features and you want to avoid backend billing entirely, our Puter.js SaaS guide describes a keyless, user-pays model. It solves a different problem than supastarter, and the two approaches can even be compared before you commit.
