You want Supabase. You want Next.js. You want to ship.
The question is which boilerplate gets you there fastest without saddle you with legacy decisions you'll regret in six months.
I've tested the top options. Here's the honest ranking.
Why Supabase + Next.js is the Default Stack in 2026
Supabase has become the de facto database for indie SaaS developers. The reasons are obvious:
- Managed PostgreSQL with a generous free tier
- Built-in auth with email, OAuth, magic links, and SSO
- Row Level Security for proper multi-tenant data isolation
- Realtime subscriptions for live UIs
- Storage for files and images
- Edge functions for server-side logic without serverless cold starts
Next.js 15 pairs perfectly because the App Router's server components work naturally with Supabase's server-side client. Your data never touches the browser unless you want it to.
The stack works. The question is how fast you can get it running with everything you need for a real product.
The Contenders
| Boilerplate | Price | Supabase | Next.js | Stripe | Multi-tenant | AI Tools |
|---|---|---|---|---|---|---|
| PropelKit | $59–$109 | Yes | 15 | Yes | Yes | Yes |
| MakerKit | $299/year | Yes | 15 | Yes | Yes | No |
| ShipFast | $199 | Yes (opt) | 14 | Yes | No | No |
| Supastarter | $199 | Yes | 14 | Yes | Yes | No |
| Nextbase | $149 | Yes | 14 | Yes | No | No |
| Indie Kit | $99–$199 | Yes | 14 | Yes | No | No |
#1: PropelKit — Best Overall for New Projects
Price: $59 (Starter) / $109 (Pro) — one-time
Next.js version: 15
Supabase integration: Full (Auth + DB + Storage + RLS)
PropelKit was built Supabase-first. The entire auth system, user management, and multi-tenancy layer is built on Supabase. This isn't an afterthought — it's the foundation.
What you get out of the box:
- Supabase Auth with email/password, OAuth (Google, GitHub), magic links
- Row Level Security policies pre-configured for multi-tenant data
- User table, organizations table, memberships — all migrated and ready
- Supabase Storage setup with scoped bucket policies
- Server and browser Supabase clients correctly separated
What makes it different:
- AI Product Manager (
/pk:start): An AI that interviews you about your product and customizes the boilerplate for your specific use case - AI credits system: Track per-user AI usage out of the box — critical for any AI SaaS
- DodoPayments support: Merchant of Record option that handles VAT and international tax automatically
- Next.js 15 from day one: Server components, Partial Prerendering, Turbopack
Honest weak point: Smaller community and less documentation than MakerKit.
Best for: Indie hackers, AI SaaS founders, international builders who need global payments, vibe coders who want a fast start.
#2: MakerKit — Best for Teams That Want Docs
Price: $299/year subscription
Next.js version: 15
Supabase integration: Full
MakerKit is the mature option. It's been around since 2021, has extensive documentation, and has a real user base.
The Supabase integration is solid and well-tested. Multi-tenancy is the most battle-hardened of any boilerplate on this list.
The trade-off: $299/year, ongoing. Over 3 years that's $897 vs PropelKit's $109.
Best for: Funded teams where cost isn't the deciding factor, developers who want the most documentation.

#3: ShipFast — Best for Quick Prototypes
Price: $199 one-time
Next.js version: 14
Supabase integration: Optional (MongoDB or Supabase)
ShipFast is the most famous boilerplate on this list. Marc Lou built it and shipped it before most of us were thinking about boilerplates.
The problem in 2026: it's on Next.js 14. That's not a dealbreaker, but it means you start with technical debt. Also $199 for something on 14 when 15 is standard feels dated.
Supabase is an option but not the default — ShipFast is more MongoDB-first.
Best for: Developers who already know ShipFast, quick marketing prototypes.
#4: Supastarter — Best Pure Supabase Focus
Price: $199 one-time
Next.js version: 14
Supabase integration: Yes (entire name is "Supa")
Supastarter is heavily Supabase-focused. If your entire stack is Supabase, this is worth looking at.
The Supabase RLS setup is excellent. Multi-tenancy works well.
The problem: Next.js 14 and a smaller community. Less actively maintained than PropelKit or MakerKit.
Best for: Developers who want maximum Supabase depth and are fine with Next.js 14.
What Actually Matters When Choosing
Row Level Security Setup
This is the most common pain point. Getting RLS right is tricky. Every user query needs to be properly scoped or you get a data breach waiting to happen.
PropelKit and MakerKit both ship with properly configured RLS for multi-tenant scenarios. ShipFast and Nextbase have more minimal setups you'll need to extend.
Check the starter's migrations and RLS policies before buying. Ask: "If I add a new table, how do I scope it to the current user or organization?"
Server vs Browser Client Separation
Next.js 15 with App Router requires careful separation between the Supabase server client (for Server Components and API routes) and the browser client (for Client Components).
Getting this wrong causes auth bugs that are very hard to debug. PropelKit and MakerKit handle this correctly out of the box. Some smaller boilerplates don't.
Webhook Handling
Stripe webhooks are the most common source of production bugs for new SaaS developers. The webhook needs to:
- Verify the Stripe signature
- Handle retries idempotently
- Update the database in a transaction
PropelKit includes a full webhook implementation with DodoPayments, Stripe, and proper idempotency. MakerKit's Stripe webhooks are also solid.
The Supabase + Next.js 15 Checklist
When evaluating any boilerplate, verify:
- Next.js 15 App Router (not Pages Router)
- Supabase server client for Server Components
- Supabase browser client for Client Components (not shared)
- RLS policies on all user-data tables
- Auth middleware protecting dashboard routes
- Multi-tenancy with org/team scoping
- Stripe webhook with signature verification
- Supabase Storage with scoped policies
- Email via Resend or similar (not SMTP)
- TypeScript with strict mode
PropelKit passes all of these. It's the only one that also adds AI tooling.
My Recommendation
If you're building a new SaaS in 2026:
Solo founder / indie hacker: PropelKit Pro ($109). Best value, AI PM is genuinely useful, one-time payment.
Team with a budget: MakerKit ($299/year). Better docs, more mature for complex B2B.
Just exploring: Either PropelKit Starter ($59) or ShipFast. Both get you running in hours.
The best boilerplate is the one you ship with. Don't spend weeks comparing — pick one, clone it, run /pk:start or the equivalent, and start building your actual product.
PropelKit is the fastest way to start a Next.js Supabase SaaS in 2026. One-time payment. AI PM included. Get PropelKit →
