Supabase: the open source backend for your data and AI apps
Discover Supabase, the open source backend for your applications
Supabase is an open source platform that provides a complete backend for your applications: database, authentication, storage, realtime and serverless functions.
Often described as an open source alternative to Firebase, Supabase is built on PostgreSQL: you get the full power of SQL, auto-generated APIs and a foundation ready for data and AI use cases. Perfect for shipping a product fast, then scaling without rewriting your stack.
Supabase is built around four pillars:
Each component works on its own, but combining them is where you save real time.
1. Database: managed PostgreSQL, ready to use
The heart of Supabase: a real relational database, with no servers to administer.
- Create and manage your tables from a visual interface or in SQL
- Expose your data through auto-generated REST APIs
- Secure access row by row with Row Level Security policies
- Scale your database without heavy administration
2. Authentication: users managed effortlessly
Sign-up, login and permissions are covered out of the box.
- Offer login via email, magic links or social accounts
- Manage user sessions, roles and permissions
- Tie authentication to your database access rules
- Integrate everything into your front end with the official SDKs
3. Storage and realtime: living applications
Files and data flow instantly between your users.
- Store and serve files, images and documents
- Broadcast data changes to your clients in real time
- Build chat, notifications or collaborative boards
- Control file access with the same security rules
4. Edge Functions and AI: business logic close to your users
Your code runs server-side, with no infrastructure to manage.
- Deploy serverless functions in TypeScript
- Run your business logic close to your users
- Store embeddings with the pgvector extension for AI use cases
- Build semantic search and assistants connected to your data
What about self-hosting?
Supabase is open source: use the managed cloud version, or host it on your own infrastructure when data control requires it.
