Supabase is an open-source backend-as-a-service built on PostgreSQL, providing a managed database, authentication, file storage, realtime subscriptions, edge functions, auto-generated APIs, and vector search — with a hosted platform and a self-hostable stack.
Developers building web, mobile, or AI applications who want a Postgres-backed backend without standing up separate services for auth, storage, and realtime — from solo/indie builders on the free tier up to production teams needing SOC2/HIPAA compliance on the Team and Enterprise plans.
A dedicated Postgres database with instant auto-generated REST and realtime APIs, built-in authentication and Row Level Security, S3-compatible object storage, globally-deployed Deno-based Edge Functions, and pgvector support for AI/vector search — all managed from one dashboard or self-hosted via Docker.
Every project provisions a dedicated Postgres instance that Supabase introspects to auto-generate a RESTful API (via PostgREST) and realtime websocket channels, while Postgres Row Level Security policies (integrated with Supabase Auth's JWTs) enforce per-row access control without a separate authorization server.
