Which Next.js SaaS Boilerplate Should You Pick in 2026? (Full Comparison)

Why use a SaaS boilerplate in 2026?

Building a SaaS from scratch in 2026 means solving the same problems the 10,000 developers before you already solved: auth, payments, multi-tenancy, emails, permissions... Every hour spent on these foundations is an hour not spent on the part of your product that actually differentiates it.

A good boilerplate buys you 2-4 weeks of head start. No magic involved: just production-ready code you don't have to write yourself.

Here's an honest comparison of the main options in 2026.

The criteria that actually matter

Before comparing, ask yourself:

• Is your stack locked in? Some boilerplates force Supabase, others Planetscale, others are agnostic.
• B2B or B2C? Multi-tenant (one DB for N customers) vs. DB-per-tenant changes everything.
• Local market or international? VAT, invoicing, GDPR: some boilerplates ignore these constraints entirely.
• What do you need most? Auth + Stripe → almost any of them works. Granular RBAC + multi-tenancy → the list gets short.

ShipFast: the pioneer

Price: from $199 (one-time payment) Stack: Next.js, NextAuth, Prisma or Mongoose, Stripe Target: Indie hackers, B2C, solo projects

ShipFast popularized the "SaaS boilerplate" concept for solo developers. Its strength: a massive community (8,000+ makers, per the ShipFast site as of September 2026) and well-built marketing integrations (SEO, blog, landing pages).

What it does well:

• Setup in under 30 minutes
• Clear documentation for beginners
• Landing page and blog included

Limitations:

• No multi-tenancy out of the box
• Basic RBAC (admin / user)
• Not built for complex B2B
• English-only content, no localization for other markets

// ShipFast: simple User model
model User {
  id            String    @id
  email         String    @unique
  name          String?
  // No Organization, no granular roles
}

MakerKit: the strongest on auth

Price: from $349 Stack: Next.js 15, Supabase, tRPC (optional), Stripe Target: B2B SaaS, teams, multi-tenant

MakerKit is serious software. Native multi-tenancy, team onboarding, organizations and members: it's the most advanced boilerplate on the "B2B workspace" side of things.

What it does well:

• Robust multi-tenancy (organizations + memberships)
• Solid permissions schema
• Stripe subscriptions and one-time payments, well integrated

Limitations:

• Higher price (and a subscription for updates)
• Tight coupling to Supabase (hard to switch away from)
• Few business-domain modules (invoicing, CRM, etc.)
• No localization for markets outside the US

SupaStarter: Supabase first

Price: from $299 Stack: Next.js, Supabase Auth, Supabase DB Target: Supabase-only projects

If you're all-in on Supabase, SupaStarter is a coherent choice. But that's also its limit: you're locked into the Supabase ecosystem for everything — auth, DB, storage, realtime.

HeartCo: built for B2B with business-domain depth

Price: $219-549 at launch (one-time) Stack: Next.js 15, Prisma 7, tRPC v11, Supabase PostgreSQL, NextAuth v5, Mistral AI Target: B2B SaaS, projects that need real business modules out of the box

HeartCo starts from a different observation: most B2B SaaS products end up rebuilding the same domain modules (invoicing, clients, quotes) that generic boilerplates never ship with.

// HeartCo: multi-tenant read isolation via Prisma $extends (simplified excerpt)
const orgDb = db.$extends({
  query: {
    $allModels: {
      async findMany({ args, query }) {
        args.where = { ...args.where, organizationId };
        return query(args);
      },
      // same principle for findFirst, findFirstOrThrow, count, aggregate, groupBy
    },
  },
});
 
// Usage inside a tRPC router
const clients = await ctx.orgDb.client.findMany();
// ↑ Equivalent to: WHERE "organizationId" = 'org_abc123'

What it does well:

• 160+ Prisma models (clients, invoices, quotes, CRM, field-service, HR...)
• 70+ production-ready tRPC routers
• Granular 8-level RBAC (permission matrix)
• Secure multi-tenancy by default (reads auto-filtered by organization, writes explicit)
• Mistral AI built in (summaries, extraction, generation)
• One-time purchase (no subscription)

Limitations:

• Steeper learning curve (a lot more code)
• Overkill for a simple B2C project
• Smaller community (newer boilerplate)

How to choose

Pick ShipFast if:

• You're shipping a simple B2C product (solo SaaS, tool, app)
• You want the fastest possible setup
• You need a large community for support

Pick MakerKit if:

• Your SaaS is a collaborative workspace (think Notion, Linear)
• You're comfortable with annual subscriptions
• Your project is 100% built on Supabase

Pick HeartCo if:

• You're building a B2B SaaS with business-domain modules (invoicing, CRM, HR, field service...)
• You want serious RBAC and airtight multi-tenant isolation
• You want AI (Mistral) built in without wiring it up yourself

What most comparisons miss

Boilerplates don't just compare on features. The real question is: how much code will you end up throwing away?

A very generic boilerplate forces you to write a lot of custom code for a B2B SaaS. An overly specialized one forces you to patch around parts you don't use.

HeartCo bets on the business domain: it's bigger, but every line of code is there for a reason. If your SaaS needs to manage invoices, clients, and projects, you don't rebuild those modules from zero.

The best way to evaluate any of these: read the source code. A good boilerplate explains itself.
