Supabase is an open source Firebase alternative that provides all the backend services you need to build a product. The platform combines enterprise-grade open source tools to give developers a complete backend-as-a-service solution.

​
What is Supabase?

Supabase is the Postgres development platform. We’re building the features of Firebase using enterprise-grade open source tools. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool.

Hosted Postgres Database

Production-ready Postgres database with automatic backups and point-in-time recovery

Authentication

Complete user management with support for email, OAuth providers, and magic links

Auto-generated APIs

Instant REST and GraphQL APIs that automatically reflect your database schema

Realtime Subscriptions

Listen to database changes in real-time using websockets

Storage

Store and serve large files with built-in image transformations

Edge Functions

Deploy serverless TypeScript functions close to your users

​
Platform Architecture

Supabase combines several open source tools into a unified platform:

​
Core Components

Object-relational database system with over 30 years of active development. Supabase runs Postgres with useful extensions like pgvector for AI/ML workloads, pg_cron for scheduled jobs, and PostGIS for geospatial data.
Cloud-native API gateway that handles routing, authentication, and rate limiting for all Supabase services.
JWT-based authentication service that handles user sign-ups, logins, password resets, and OAuth integrations.
Web server that automatically generates a RESTful API from your PostgreSQL database schema. No backend code required.
Elixir server that listens to PostgreSQL replication logs and broadcasts database changes over websockets to subscribed clients.
RESTful interface for managing files in S3-compatible storage, with Postgres handling permissions and access control.
Deno-based runtime for deploying serverless TypeScript, JavaScript, and WASM functions at the edge.
Web-based dashboard for managing your database, viewing logs, running SQL queries, and configuring authentication providers.
