Best SaaS Boilerplates with Supabase in 2026

Q: What Supastarter Includes (Supabase-specific)?

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 alone — multi-tenancy, RLS policies, and Stripe billing all pre-wired means you skip weeks of infra

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 alone — multi-tenancy, RLS policies, and Stripe billing all pre-wired means you skip weeks of infrastructure work.

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.

Decision Guide

"I want the most complete Supabase boilerplate, money isn't an issue"
→ Supastarter ($299) — multi-tenancy, i18n, admin, blog all included

"I want free and complete enough for a real product"
→ Open SaaS — Stripe + auth + admin for $0

"I want free and I'll add features myself"
→ Next SaaS Starter — minimal, clean codebase to build on

"I want to ship in days, not weeks, I'll figure out advanced features later"
→ ShipFast — best reputation, fastest to launch

"I want full TypeScript type safety with tRPC"
→ T3 Stack + Supabase as Postgres host

"I'm building something with complex data access rules"
→ Supastarter — pre-written RLS policies save weeks of work

"I need file uploads from day one"
→ Supastarter — Storage buckets and policies pre-configured

"I need realtime collaboration features"
→ Supastarter — realtime already wired into notifications
→ or any boilerplate + add Supabase Realtime subscriptions manually

The Bottom Line on Cost

The $299 for Supastarter looks expensive until you calculate what you'd spend building multi-tenancy, RLS policies, storage policies, and realtime notifications from scratch — typically 2-4 weeks of engineering time at any hourly rate. If you value your time at even $20/hour, Supastarter pays for itself in the first working day. The free options (Open SaaS, Next SaaS Starter) are excellent if you have more time than budget and want to understand the full stack architecture. ShipFast sits in the middle — paid, but focused on speed to launch rather than depth of Supabase integration. Choose based on whether you're optimizing for learning, cost, or time-to-launch velocity — all five are solid, well-maintained Supabase-powered foundations for building SaaS in 2026.

Supabase Row Level Security: The Underrated Feature

Every boilerplate that ships with Supabase pre-configured should also ship with Row Level Security (RLS) policies pre-written. This is where Supastarter earns its price — it's the only boilerplate in this list where you don't have to write RLS policies from scratch.

RLS lets you enforce data access rules at the database level instead of in your application code:

-- RLS policy: users can only read their own data
CREATE POLICY "Users can view own profile"
  ON profiles FOR SELECT
  USING (auth.uid() = user_id);

-- Multi-tenant: users can only access their org's data
CREATE POLICY "Org members can view org data"
  ON projects FOR SELECT
  USING (
    org_id IN (
      SELECT org_id FROM memberships
      WHERE user_id = auth.uid()
    )
  );

-- Allow org admins to manage members
CREATE POLICY "Org admins can manage memberships"
  ON memberships FOR ALL
  USING (
    EXISTS (
      SELECT 1 FROM memberships
      WHERE org_id = memberships.org_id
      AND user_id = auth.uid()
      AND role = 'admin'
    )
  );

When these policies are pre-written (Supastarter does this), you inherit correct data isolation by default. When they're not (Next SaaS Starter, ShipFast, T3 Stack), you have to write them yourself — and missing a policy is a data leak waiting to happen.

The practical impact: For a solo project with no teams, RLS is optional. For B2B SaaS with teams and orgs, pre-written RLS policies are worth $200 on their own.

Supabase Realtime: When You Actually Need It

Realtime subscriptions are one of Supabase's standout features — but most SaaS products don't need them at launch. Understanding when to reach for realtime (and when not to) saves you from over-engineering:

// Realtime subscription — use when you need live updates:
const channel = supabase
  .channel('project-changes')
  .on(
    'postgres_changes',
    {
      event: '*',
      schema: 'public',
      table: 'tasks',
      filter: `project_id=eq.${projectId}`,
    },
    (payload) => {
      // Update UI when any task in the project changes
      setTasks(prev => updateTask(prev, payload));
    }
  )
  .subscribe();

// Don't forget cleanup:
return () => { supabase.removeChannel(channel); };

Use Supabase Realtime for:

Collaborative editing (multiple users editing the same document)
Live dashboards (metrics that update as events occur)
Chat or messaging features (new messages appear immediately)
Kanban boards (cards move in real-time across team members)
Notifications (bell icon updates without polling)

Don't use Supabase Realtime for:

Basic CRUD applications (polling or refetch-on-focus is simpler)
Data that updates less than once per minute (ISR is better)
High-frequency sensor data (use a dedicated timeseries database)

Only Supastarter comes with realtime wired into its notification system. For the others, realtime is a feature you add when you need it.

Supabase Pricing in Production: What to Expect

Supabase's free tier is generous — 500MB database, 5GB bandwidth, 1GB storage, 50,000 monthly active users. For most SaaS products at launch, you won't hit these limits.

When you grow past the free tier, Supabase Pro is $25/month and covers most scaling needs:

Resource	Free	Pro ($25/mo)
Database	500MB	8GB
Bandwidth	5GB	250GB
Storage	1GB	100GB
MAUs	50,000	100,000
Edge Functions	500K invocations	2M invocations
Realtime connections	200	500

For most indie SaaS projects, Supabase Pro at $25/month is the right tier from $1K-$10K MRR. After that, compute add-ons ($10-$100/month for more CPU/RAM) handle most scaling needs.

The boilerplates that abstract over Supabase most completely (Supastarter) make it easier to migrate between tiers since all queries go through the same client — there's no scattered raw SQL to update when your connection string changes.

Supabase Storage: File Uploads Done Right

Supabase Storage is the most underused Supabase feature in SaaS boilerplates. Most starters skip it, defaulting to "add S3 later" — but Supabase Storage has fine-grained access control that integrates directly with your RLS policies.

// Supabase Storage with per-user access control:
// 1. Create a private bucket with user-scoped policies

// storage policy (in Supabase dashboard or migration):
// "Users can upload their own files"
// USING (auth.uid() = (storage.foldername(name))[1]::uuid)

// 2. Upload with the authenticated client (server-side):
const supabase = await createClient(); // server client with user session

const { data, error } = await supabase.storage
  .from('user-files')
  .upload(`${userId}/${filename}`, file, {
    cacheControl: '3600',
    upsert: false,
  });

// 3. Generate a signed URL for temporary access:
const { data: urlData } = await supabase.storage
  .from('user-files')
  .createSignedUrl(`${userId}/${filename}`, 60 * 60); // 1 hour

return { url: urlData.signedUrl };

Among the boilerplates in this guide, only Supastarter ships with Storage buckets and policies pre-configured. Open SaaS supports S3 uploads (not Supabase Storage), while ShipFast and Next SaaS Starter leave storage as an exercise for the developer. For SaaS products with user-generated content — profile pictures, document uploads, export files — having storage configured from day one removes a full day of setup work.

Getting Started: Estimated Setup Time

How long does it actually take to get from zero to a running SaaS with each boilerplate?

Boilerplate	Time to Running Locally	Time to First Deploy	Time to First Subscription
Supastarter	30 minutes	2 hours	2 hours
Open SaaS	45 minutes	3 hours	3 hours
Next SaaS Starter	20 minutes	1 hour	2 hours
ShipFast	15 minutes	1 hour	1.5 hours
T3 Stack + Supabase	1 hour	3 hours	8+ hours (billing DIY)

Notes:

Supastarter's 30-minute local setup requires running supabase start via the Supabase CLI and pnpm run db:push — both are documented in their README
ShipFast's 15-minute setup time comes from well-maintained docs and a single .env file setup
T3 Stack's billing timeline is open-ended because you build it yourself

For indie hackers optimizing for time-to-launch, ShipFast or Next SaaS Starter win on setup speed. For teams who will build on the foundation for months, Supastarter's initial investment saves time later.

Supabase Free Tier: What You Get and When You Pay

Supabase's free tier is genuinely usable for a real product:

Resource	Free Tier	Pro Tier ($25/month)
Database	500 MB storage	8 GB (then $0.125/GB)
Auth	50,000 MAU	Unlimited
Storage	1 GB	100 GB
Edge Functions	500K invocations/month	2M/month
Realtime	200 concurrent connections	500 concurrent
Row-level Security	Unlimited	Unlimited

For a new SaaS: you'll likely stay on the free tier until you have meaningful revenue. At 1,000 monthly active users, you probably haven't hit any limits. At 10,000 MAU, you'll want to check your auth numbers and storage usage.

The Pro tier ($25/month per project) also unlocks:

Daily backups — 7-day point-in-time recovery
No connection limits — free tier has a 200-connection cap (Supavisor pooler helps, but it's a known constraint)
Custom domains — your Supabase project URL can be db.yourapp.com instead of xyz.supabase.co
Priority support — GitHub issue response vs email queue

Most early-stage products should start on free and upgrade when the friction of hitting limits is costing more time than $25/month.

→ Supastarter — pre-written RLS policies and org-scoped data save weeks

Pros and Cons for Each Option

Supastarter ($299)

Pros:

Row Level Security policies pre-written for all tables — a major time save for developers unfamiliar with Supabase's RLS model
True multi-tenancy with organizations, member invitations, and role-based access in a production-ready implementation
Active development and a dedicated Discord community for support
Covers both Next.js and Nuxt.js flavors — rare among paid starters
i18n (internationalization) included — 20+ languages pre-configured

Cons:

$299 is a significant upfront cost for solo developers or projects in early validation
More opinionated than lighter starters — deviating from the Supastarter patterns requires understanding them first
No Drizzle ORM option (Prisma only as of March 2026); Drizzle adoption is growing in the Next.js community
Closed source — you depend on the maintainer for updates and bug fixes

Open SaaS (Free)

Pros:

Zero cost — the most complete free Supabase alternative available
Admin dashboard and analytics included — rare for any free starter
Stripe subscriptions pre-configured with webhook handling
MIT licensed — full ownership and modification rights

Cons:

Wasp framework learning curve — the .wasp config file and operation system take time to understand
Supabase is used as a Postgres host only — Supabase Auth, RLS, Realtime, and Storage aren't part of the Wasp architecture
Smaller community than ShipFast or T3 Stack

Next SaaS Starter (Free)

Pros:

Cleanest Supabase Auth integration available in a free Next.js starter
Minimal dependencies — easy to audit and understand completely
Regular updates tracking Supabase SDK changes

Cons:

No multi-tenancy, admin panel, or advanced billing features
Limited to individual user subscriptions
Less documentation than Supastarter

ShipFast ($199–$299)

Pros:

Largest community reputation in the paid Next.js SaaS starter market
Marc Lou's documentation and Discord community are exceptional resources
Fastest path to a deployed, working product with Stripe and auth
Regular updates with new features and Supabase SDK compatibility

Cons:

Supabase implementation is shallow — RLS policies, Realtime, and Storage are left for you to configure
No multi-tenancy or team features
Supabase is optional (NextAuth is the alternative) — Supabase-specific features aren't first-class

Upgrading Path: Free → Paid

A common pattern for solo founders: start with a free option to validate the idea, then migrate to a paid boilerplate when the product generates revenue.

Free → Paid migration friction varies:

T3 Stack → MakerKit/Supastarter: High friction — different auth systems (NextAuth vs Supabase Auth), different data access patterns. Plan a 1-2 week migration.
Next SaaS Starter → Supastarter: Medium friction — both use Supabase Auth; the main work is adopting Supastarter's organization structure.
Open SaaS → ShipFast: High friction — different framework (Wasp vs Next.js), different auth system, different billing implementation.

If you expect to upgrade, start with Next SaaS Starter — its Supabase Auth implementation is close to Supastarter's, making future migration more tractable.

GitHub Stars and Maintenance (April 2026)
