Postgres-native Backend-as-a-Service with Auth, Storage, Realtime
Supabase wraps Postgres in a polished BaaS layer: Auth, Storage, Realtime subscriptions, Edge Functions, and an Admin dashboard. The bet on Postgres (not Firebase's Firestore) means SQL, joins, and RLS policies you can reason about. Self-hostable, open-source, but the cloud product is where the polish lives. Connection pooling has historical edge cases at high RPS.
The cohesive Postgres-on-edge platform.
Auth + DB + Storage + Realtime in one SDK. We replaced Firebase + Stripe Customer Portal + S3 + Pusher with one Supabase. RLS policies are the killer feature — auth flows through SQL, not custom middleware.
Postgres is the moat. Everything else is convenient packaging.
After 4 years on Firebase the join queries finally make sense. Supabase didn't reinvent the database — they wrapped a great one well.
Don't use it if you need >5K RPS without pooling work.
We hit Postgres connection-pool limits at 6K RPS. Migrated heavy reads to Neon. Supabase still owns auth and realtime. The right answer was hybrid, not single-vendor.
