Best Next.js SaaS Boilerplate in 2026 (Compared: Stack, Price, Features)

Picking a SaaS boilerplate is one of the first and most consequential decisions when starting a new project. Choose wrong and you spend the first two weeks fighting the template instead of building your product.

In 2026, there are five serious options in the Next.js space. I have looked at all of them — some I have used personally, some I have dug into the code. Here is an honest comparison.

The Contenders

ShipFast — The most popular indie hacker kit
Supastarter — The polished, full-featured option
Makerkit — The enterprise-leaning kit
LaunchKit — The modern, AI-native option
Blitz.js — The Rails-inspired full-stack framework

1. ShipFast

Price: $169 one-time

Stack:

Next.js Pages Router
NextAuth v4
Tailwind CSS v3
MongoDB or Supabase (choose at setup)
Stripe

What it does well:
ShipFast has the best marketing, the largest community, and the most polish in terms of landing page and documentation. Marc Lou has built a brand around it, and the indie hacker community trusts it. If you want the most battle-tested option with the most people to ask for help, ShipFast is it.

What to watch out for:
It is built on Pages Router and NextAuth v4 — older foundations. App Router is the future of Next.js. You are starting with technical debt baked in from day one. Also at $169, it is among the pricier options.

Best for: Developers who want community support and do not mind older stack choices.

2. Supastarter

Price: $249 one-time (or subscription tiers)

Stack:

Next.js App Router
Supabase (auth + DB)
Tailwind CSS v3
Stripe
i18n support

What it does well:
Supastarter is genuinely polished. It has internationalization (i18n) out of the box, team/org support, a clean UI component library, and good documentation. If you are building a B2B SaaS with multi-tenancy needs, Supastarter covers a lot of ground.

What to watch out for:
Heavy Supabase dependency — auth, database, storage are all Supabase. That is fine if you love Supabase, but if you want portability, you are locked in. It is also the most expensive option on this list. No AI features.

Best for: Developers building multi-tenant B2B SaaS who want polished i18n and team features.

3. Makerkit

Price: $299+ (subscription-based)

Stack:

Next.js App Router
Supabase or Firebase
Tailwind CSS
Stripe or Lemon Squeezy
Multi-tenancy built-in

What it does well:
Makerkit is the most "enterprise" of the bunch. It has multi-tenancy, role-based access control, a full admin panel, and a plugin architecture. The subscription pricing means you get updates continuously. If you are building something where security and role management are critical from day one, Makerkit is serious.

What to watch out for:
The learning curve is steep. There is a lot of abstraction and configuration. It is also the most expensive — the subscription model means ongoing cost. For a solo founder or indie hacker, it may be more than you need.

Best for: Teams building enterprise SaaS that need multi-tenancy and RBAC from day one.

4. LaunchKit

Price: $49 one-time

Stack:

Next.js 16 App Router
Auth.js v5
Tailwind CSS v4
Prisma + PostgreSQL
Stripe
Vercel AI SDK (built-in)

What it does well:
LaunchKit is built on the most modern stack available in 2026. Everything is current — App Router, Auth.js v5 (the complete rewrite with proper TypeScript), Tailwind v4, and critically, AI features are wired up from day one. The Vercel AI SDK integration means you can ship streaming AI features in minutes.

At $49, it is dramatically cheaper than the competition. The code is clean, TypeScript is strict throughout, and Prisma gives you full schema control without vendor lock-in.

What to watch out for:
Smaller community than ShipFast. Documentation is good but not as exhaustive as Supastarter. If you need built-in i18n or multi-tenancy, you will need to add those yourself.

Best for: Solo developers and indie hackers building modern SaaS with AI features. Best price-to-stack ratio on the market.

5. Blitz.js

Price: Free (open source)

Stack:

Next.js (under the hood)
Prisma
Built-in auth (Passport.js based)
No Stripe integration

What it does well:
Blitz is a full-stack Rails-inspired framework built on Next.js. It has RPC-style queries and mutations, which feels very clean. If you love the Rails mental model and want it in JS, Blitz is interesting.

What to watch out for:
Blitz has had some turbulent times with maintenance and the Blitz v2 "toolkit" pivot. It is free, but the trade-off is you build more from scratch. No payment integration, no email setup, no deployment config. Also smaller ecosystem.

Best for: Developers who want the Rails experience in Next.js and are comfortable assembling the rest themselves.
