Supabase

Supabase is an open source Postgres development platform for building web, mobile, and AI applications. It combines PostgreSQL with a set of services for authentication, instant APIs, realtime updates, serverless functions, and file storage.

Key Features

• Dedicated PostgreSQL database with SQL, roles, and Row Level Security
• Auto-generated REST APIs from your database schema
• Optional GraphQL API via a PostgreSQL extension
• Authentication and authorization with JWT-based sessions and OAuth2 support
• Realtime subscriptions over WebSockets driven by PostgreSQL changes
• File storage service with access control policies backed by Postgres
• Edge/serverless functions for custom backend logic
• Vector/embeddings support using Postgres extensions (for semantic search and RAG patterns)
• Web-based dashboard for managing projects, data, and configuration

Use Cases

• Replace or self-host a Firebase-like backend for apps with Postgres
• Build internal tools and SaaS backends with auth, APIs, and storage
• Create AI-enabled applications using Postgres vector search and embeddings

Limitations and Considerations

• Some functionality relies on multiple cooperating components (database, realtime, auth, storage, gateway), which increases operational complexity compared to a single service
• Feature set and behavior can vary depending on the chosen self-hosting setup and enabled extensions

Supabase provides a cohesive backend stack around PostgreSQL while keeping data ownership and portability. It is well-suited for teams that want a modern developer experience with SQL and strong database-native security controls.
