Supabase REST API
Supabase is an open-source Firebase alternative built on PostgreSQL that auto-generates a RESTful API (via PostgREST) from your database schema. Every table and view immediately gets CRUD endpoints at your-project.supabase.co/rest/v1/. Supabase also provides a Management API for provisioning and managing projects programmatically, a Realtime API for subscribing to database changes, an Auth service (JWT-based), and an official MCP server for AI agent integration. The platform combines multiple services — database, auth, storage, edge functions, and realtime — behind a single project interface, making it particularly powerful for agents that need to manage the full application stack.
Best When
You want a complete backend platform (database + auth + storage + realtime + API) on top of PostgreSQL, with excellent developer tooling, an auto-generated REST API, and MCP server support for AI agent workflows.
Avoid When
You only need a PostgreSQL database without the platform features, or you're running on-premise without cloud access.
Use Cases
- • Auto-generated REST CRUD API over PostgreSQL tables without writing any backend code
- • Agent-driven schema changes using the Supabase Management API (create tables, add columns, run migrations)
- • Real-time data subscriptions for agents monitoring live database changes via WebSocket
- • User authentication and session management using Supabase Auth with JWT verification
- • File storage operations via Supabase Storage with auto-generated signed URLs
- • Multi-project provisioning for multi-tenant SaaS using the Management API
Not For
- • Non-Supabase PostgreSQL databases (use direct pg drivers or PostgREST self-hosted instead)
- • Extremely high-throughput OLAP analytics (Supabase PostgreSQL is OLTP-optimized)
- • Teams requiring on-premise deployment without cloud connectivity
- • Applications needing sub-10ms latency without read replicas (Supabase has geo-routing but single region by default)
