Makerkit
PaidProduction-grade SaaS starter kits for Next.js and React Router with Supabase — multi-tenant teams, roles and permissions, billing via Stripe or Lemon Squeezy, a super-admin panel, and tests included. Paid, from $299 one-time.
Why we recommend Makerkit
Makerkit sits at the serious end of the paid-boilerplate spectrum: where ShipFast optimizes for the fastest possible launch, Makerkit optimizes for the codebase you'll still be running two years in. The kit is a Turborepo monorepo with real multi-tenant team accounts, role-based permissions, per-team billing (Stripe or Lemon Squeezy), a super-admin back office, and — rare in this market — an actual test suite. The maintainer ships updates continuously and documents architecture decisions instead of just features, which makes it one of the few paid kits you can defend in a code review with professional engineers.
Best use cases
Best for: bootstrapped B2B SaaS where team accounts and roles are needed on day one, agencies standardizing client SaaS builds on one stack, and developers who want Supabase best practices (RLS policies, typed queries) already encoded rather than learned by trial and error.
Honest limitations
Not for: quick weekend experiments — the monorepo structure and conventions have a real learning curve, overkill for a landing page with one checkout. Paid (from $299 one-time) and closed-source. You commit to the Supabase + Turborepo worldview; swapping either means fighting the kit.
