Frequently asked questions

How does Supabase compare to Firebase?: Supabase is an open-source Firebase alternative built on PostgreSQL. Unlike Firebase's NoSQL (Firestore), Supabase uses a relational database with full SQL support. It offers auth, storage, edge functions, and real-time subscriptions — all self-hostable with no vendor lock-in.
Can I migrate from Firebase to Supabase?: Yes, Supabase provides migration guides and tools for moving from Firebase. Firestore data can be exported to CSV/JSON and imported into PostgreSQL tables. Auth users can be migrated, though some provider-specific tokens may need re-authentication.
Does Supabase support row-level security?: Yes, Supabase leverages PostgreSQL's row-level security (RLS) policies. You can define fine-grained access rules per table based on the authenticated user, their role, or any custom logic — all enforced at the database level.
How much resources does self-hosted Supabase need?: Self-hosted Supabase runs multiple services (PostgreSQL, GoTrue, PostgREST, Realtime, Storage). Minimum recommended is 4GB RAM and 2 CPU cores. For production with moderate traffic, 8GB RAM provides comfortable headroom.
