Supabase
Open-source Firebase alternative
Postgres database, authentication, realtime subscriptions, edge functions, and storage — all with auto-generated APIs and row-level security.
Best for
- Postgres + RLS
- Auth
- Realtime
- Storage
How builders use it
- →Design tables + RLS first; let the agent generate clients against a real schema.
- →Never bypass RLS for convenience — policies are the security model.
- →Works cleanly with Lovable scaffolds and hand-rolled Next.js / Cursor apps.
