Supabase

The open-source Firebase alternative: Postgres, auth, storage and more.

Supabase is an open-source backend-as-a-service platform positioned as a Firebase alternative, built around a managed PostgreSQL database. It bundles auto-generated REST and GraphQL APIs, authentication, row-level-security authorization, file storage, realtime subscriptions, edge functions, and vector/embedding support. It is notable for being Postgres-native and fully self-hostable while also offering a hosted service.
