Both products use Supabase. Why pick one over the other?

Pick Supastarter if Supabase being the entire foundation matters and a tightly-scoped repo is a feature. Pick Boilerlykit Core if you want broader B2B primitives (audit logs, SAML hooks, API keys) on day one or want an AI template under the same design system.

Does Boilerlykit lock me into Supabase?

Boilerlykit is Supabase-first but documented for seam-by-seam extension. You can swap parts (auth provider, vector store) without rewriting the whole template. Supastarter is more opinionated about Supabase being the entire stack.

Which has better RAG support?

Boilerlykit AI ships a full RAG pipeline (uploads → chunking → embeddings → pgvector retrieval) tied to a credit economy. Supastarter does not position RAG as a primary feature; you would build that pipeline yourself.

Can I migrate from Supastarter to Boilerlykit?

Yes — both run on Supabase Postgres so the data layer maps cleanly. The main work is moving auth flows and any custom UI; the schema concepts (workspaces, RLS) translate directly.

Boilerlykit vs Supastarter

Pick Boilerlykit when…

You want enterprise primitives — 2FA/TOTP, SAML SSO hooks, API keys, audit logs — on day one.
You also need an AI template (RAG + credits) under the same design system.
You want EN/FR/ES out of the box for an agency-shaped marketing site.
You want a lower price floor with $59 Starter for a content-only shell.

Pick Supastarter when…

Your entire roadmap is bound to Supabase and you want a boilerplate that treats Supabase as the entire foundation, not an interchangeable BaaS.
You prefer a single tightly-scoped repo over a four-template product line.
You like Supastarter's specific code style and conventions after reading the repo.

We mark the cases where Supastarter is the better fit because one-sided comparisons hurt buyer trust and AI citation rates.
