Best SaaS Boilerplates with Supabase in 2026

TL;DR

Supabase has become the default backend for indie SaaS builders — Postgres + auth + storage + realtime in one hosted service. The best boilerplates that ship with Supabase pre-configured: Supastarter (most complete, $299+), Open SaaS (free, Wasp-based), Next SaaS Starter (free, Next.js), and ShipFast (optional Supabase auth). This guide compares what each actually includes, so you can pick the one that fits your project.

Key Takeaways

• Supastarter: most batteries-included Supabase boilerplate — auth, multi-tenancy, billing, i18n, docs
• Open SaaS: 100% free, Supabase + Wasp, good for learning and small projects
• Next SaaS Starter: free, minimal, Next.js 15 App Router + Supabase Auth
• ShipFast: Supabase is one of two auth options (alongside Next-Auth)
• T3 Stack: officially Postgres/Prisma — can use Supabase as the Postgres host easily
• Why Supabase: Row Level Security, realtime subscriptions, storage, edge functions — more than just a DB

Why Supabase Dominates in Boilerplates

Before diving into boilerplates, it's worth understanding why Supabase is the default:

Supabase gives you for free (up to generous limits):
→ PostgreSQL database (the industry standard)
→ Auth: email/password, OAuth, magic links, OTP
→ Row Level Security (data access rules at DB level)
→ Realtime: subscribe to DB changes via websockets
→ Storage: file uploads with access control policies
→ Edge Functions: serverless functions close to users
→ REST and GraphQL APIs auto-generated from your schema

Alternative: Firebase (Google)
→ NoSQL (Firestore) — less queryable, no SQL
→ More expensive at scale
→ Google lock-in

Alternative: Railway/Neon/PlanetScale
→ Postgres only, no auth/storage/realtime
→ More control, but you wire up auth separately

For solo founders and small teams: Supabase is the obvious choice.

1. Supastarter — The Most Complete Option

Price: $299 (Next.js) / $349 (with Nuxt) Stack: Next.js 15 / Nuxt 3 + Supabase + Stripe/Lemon Squeezy + shadcn/ui GitHub stars: Private repo (purchase-based)

Supastarter is built around Supabase and is the most comprehensive boilerplate in this category. Everything is pre-configured.

What Supastarter Includes (Supabase-specific)

// Auth — Supabase Auth pre-configured:
// - Email/password
// - Magic links
// - Google, GitHub, etc. OAuth
// - Session management with SSR support

import { createClient } from '@/utils/supabase/server';

export async function GET(request: Request) {
  const supabase = await createClient();
  const { data: { user } } = await supabase.auth.getUser();
  if (!user) return new Response('Unauthorized', { status: 401 });

  const { data: subscription } = await supabase
    .from('subscriptions')
    .select('*')
    .eq('user_id', user.id)
    .single();

  return Response.json({ user, subscription });
}

// Multi-tenancy — organization model:
// users → members → organizations
// RLS policies pre-written for all tables

// Storage — file uploads pre-configured:
const { data } = await supabase.storage
  .from('avatars')
  .upload(`${user.id}/avatar.png`, file);

Supastarter's Supabase extras:

• Migration files ready to run (supabase db push)
• RLS policies for all tables pre-written
• Realtime subscriptions wired into the notifications system
• Storage buckets and policies configured
• Supabase CLI integration in package.json scripts

Best for: Teams who want to move fast with Supabase and need all features pre-built. The $299 price pays for itself in the first week of not having to wire up multi-tenancy.

2. Open SaaS — Free + Wasp

Price: Free (MIT) Stack: Wasp + React + Node.js + Supabase (or Postgres) GitHub: wasp-lang/open-saas — 9K+ stars

Open SaaS is fully free and surprisingly complete. It uses Wasp — a full-stack framework that generates boilerplate — with Supabase as a Postgres provider.

// main.wasp — Wasp's config file:
app SaaSApp {
  wasp: { version: "^0.13.0" },
  title: "My SaaS",
  auth: {
    userEntity: User,
    methods: {
      email: { fromField: { name: "My SaaS", email: "noreply@mysaas.com" } },
      google: {},
      gitHub: {},
    },
    onAuthFailedRedirectTo: "/login",
  },
}

// Wasp automatically generates:
// - /login, /signup, /reset-password pages
// - JWT session management
// - useAuth() hook
// - Auth middleware for all operations

Open SaaS features (free):

• Authentication (email + Google + GitHub)
• Stripe subscriptions (webhook handling included)
• Admin dashboard
• Blog (Astro-based, separate static site)
• Email via SendGrid
• Plausible analytics integration
• Full TypeScript support

Connecting to Supabase:

# .env
DATABASE_URL="postgresql://postgres:[password]@db.[project-ref].supabase.co:5432/postgres"

# That's it — Wasp uses Prisma under the hood
# Supabase is just the Postgres host
# You won't use Supabase Auth (Wasp has its own)
# You CAN use Supabase Storage and Realtime if needed

Best for: Developers who want to learn without paying, or who want a production SaaS at zero upfront cost.

3. Next SaaS Starter — Minimal Free Option

Price: Free (MIT) Stack: Next.js 15 App Router + Supabase Auth + Stripe + Tailwind GitHub: nextjs-saas/nextjs-saas-starter — 5K+ stars

Next SaaS Starter is the minimal free option. It's lightweight by design — no plugin system, no multi-tenancy — just the core features you need to start.

// Supabase Auth with Next.js App Router:
// app/auth/callback/route.ts
import { createRouteHandlerClient } from '@supabase/auth-helpers-nextjs';
import { cookies } from 'next/headers';

export async function GET(request: Request) {
  const { searchParams, origin } = new URL(request.url);
  const code = searchParams.get('code');

  if (code) {
    const supabase = createRouteHandlerClient({ cookies });
    await supabase.auth.exchangeCodeForSession(code);
  }

  return Response.redirect(`${origin}/dashboard`);
}

// Protected route pattern:
// app/dashboard/page.tsx
import { createServerComponentClient } from '@supabase/auth-helpers-nextjs';

export default async function DashboardPage() {
  const supabase = createServerComponentClient({ cookies });
  const { data: { session } } = await supabase.auth.getSession();

  if (!session) redirect('/login');

  return <Dashboard user={session.user} />;
}

Included:

• Supabase Auth (email + OAuth)
• Stripe subscriptions + webhook
• shadcn/ui components
• Middleware-based auth protection
• Dashboard layout
• Marketing landing page

Missing vs Supastarter: Multi-tenancy, admin panel, i18n, blog, storage setup, team management.

Best for: Solo founders building a simple B2C SaaS who want to customize heavily.

4. ShipFast — Supabase as an Option

Price: $199-$299 Stack: Next.js + Supabase Auth OR NextAuth.js (your choice) By: Marc Lou (indie hacker, 200K+ followers)

ShipFast is the most popular SaaS boilerplate by reputation. It offers Supabase Auth as one of two auth options:

// ShipFast Supabase config (libs/supabase.ts):
import { createBrowserClient } from '@supabase/ssr';

export const supabase = createBrowserClient(
  process.env.NEXT_PUBLIC_SUPABASE_URL!,
  process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!
);

// Helper for protected routes:
export async function getUser() {
  const { data: { user } } = await supabase.auth.getUser();
  return user;
}

ShipFast's Supabase implementation:

• Auth: email + magic link + OAuth
• Database: Postgres via Supabase (Prisma or raw SQL queries)
• Storage: basic setup (not pre-configured beyond example)
• No multi-tenancy built-in
• No RLS policies pre-written

ShipFast's strengths (not Supabase-specific):

• Fastest to a working landing page + auth + payments
• Marc Lou's documentation and Discord community
• Frequent updates and new features

Best for: Shipping a product in a week. If you need Supabase-specific features like RLS, realtime, or storage — add them yourself or use Supastarter.

5. T3 Stack — Supabase as Postgres Host

Price: Free (MIT) Stack: Next.js + TypeScript + Prisma + tRPC + Tailwind GitHub: t3-oss/create-t3-app — 25K+ stars

The T3 Stack doesn't use Supabase by default, but Supabase is the most common Postgres host used by T3 developers. You get Supabase's database while keeping Prisma as your ORM.

# Create T3 app:
npm create t3-app@latest

# Connect Supabase Postgres:
# .env:
DATABASE_URL="postgresql://postgres.[ref]:[password]@aws-0-us-east-1.pooler.supabase.com:6543/postgres"
DIRECT_URL="postgresql://postgres.[ref]:[password]@db.[ref].supabase.co:5432/postgres"

# prisma/schema.prisma:
datasource db {
  provider  = "postgresql"
  url       = env("DATABASE_URL")
  directUrl = env("DIRECT_URL")  # For migrations
}

Using Supabase Storage with T3:

// lib/storage.ts
import { createClient } from '@supabase/supabase-js';

const supabase = createClient(
  process.env.NEXT_PUBLIC_SUPABASE_URL!,
  process.env.SUPABASE_SERVICE_ROLE_KEY! // server-side
);

export async function uploadFile(bucket: string, path: string, file: File) {
  const { data, error } = await supabase.storage
    .from(bucket)
    .upload(path, file);
  if (error) throw error;
  return supabase.storage.from(bucket).getPublicUrl(path).data.publicUrl;
}

Best for: Developers who want full type safety end-to-end (tRPC + Prisma) with Supabase as the infrastructure layer.
