SaaS boilerplate comparison
Boilerplate-Stack vs supastarter
Both products are serious SaaS foundations with authentication, payments, organizations, administration, localization and AI-coding context. The useful decision is not which feature list is longer, but which architecture and licence match the product you intend to maintain.

supastarter currently advertises Next.js, Nuxt and TanStack Start options, Better Auth, several payment providers, organization support, AI agent skills and one-time plans. Its Solo plan is advertised for one developer with unlimited personal projects and lifetime updates.

Which one fits your project?
Choose Boilerplate-Stack when…
- You want Supabase Auth, Postgres, Storage and RLS to form one explicit tenant boundary.
- Your product needs multi-provider AI, RAG, credits and EU AI Act transparency in the shipped application.
- You value executable security, database and browser QA alongside the feature implementation.
Choose supastarter when…
- You need a Nuxt or TanStack Start option in addition to Next.js.
- You want to select from several billing providers without starting from Stripe.
- Unlimited personal projects and lifetime updates are more important than a lower one-project entry price.
