Supabase is a backend for your app. Database, auth, storage, realtime, and server functions — all from one SDK. Built on Postgres, so your data stays portable.
For the full reference, the Supabase docs.
Five pieces
- Database. Full Postgres with SQL, indexes, triggers.
- Auth. Email, phone, Google, Apple, and 20+ social providers.
- Storage. File uploads with public or signed URLs.
- Realtime. Subscribe to row changes as a stream.
- Edge Functions. Deno functions for logic that can't run on the client.
All five share the same users.
