✓ Use when

Web and mobile apps that want a full backend without building auth, storage, and APIs from scratch — especially strong for AI apps needing pgvector.

✗ Avoid when

Complex enterprise workloads requiring fine-grained Postgres tuning — raw RDS or self-managed Postgres gives more control.

What is Supabase?

Supabase wraps open-source Postgres with a suite of backend services: authentication (GoTrue), storage, realtime subscriptions via logical replication, edge functions (Deno), and pgvector for AI. Generated REST and GraphQL APIs make it a fast backend for web and mobile apps. Self-hostable end to end, which differentiates it from Firebase. Huge with indie developers and AI-app builders.
