Supabase
Supabase
Postgres-first development platform providing hosted Postgres, Auth, instant APIs, Realtime, Functions, Storage and vector embeddings.
Key features
- Hosted Postgres Database: Provides a managed, dedicated PostgreSQL instance with tools and integrations designed for production web, mobile, and AI applications.
- Auto-generated APIs: Instantly exposes REST and GraphQL endpoints from the Postgres schema (PostgREST/Graphile-style auto-APIs) so developers can query and mutate data without writing backend code.
- Authentication and Authorization: Built-in user management, sign-up/sign-in flows, JWT-based auth, and role/row-level security integrations to secure database access.
- Realtime Subscriptions: Change-data-capture based realtime updates and WebSocket subscriptions to push database changes to clients for live features like chat or presence.
- Functions (Edge & Database): Support for serverless Edge Functions alongside Postgres database functions (RPC) to run custom business logic close to data.
- File Storage: Object storage for uploading, serving, and managing files/media with access controls integrated with Supabase Auth.
- Vector Embeddings Toolkit: Integration with pgvector and embedding tooling for semantic search, similarity queries, and AI-driven features.
- Client Libraries & Local Dev: Official SDKs (e.g., supabase-js), dashboard, CLI and local stack tooling (npx supabase start) for rapid development and self-hosting.
