Supabase is an open-source backend as a service (BaaS) that streamlines data management and user authentication using the Postgres database, making it suitable for both technical and not so-technical users.
Supabase is an innovative, open-source backend platform that simplifies data management and user account handling. Designed as an alternative to Firebase, it provides similar functionalities but avoids vendor lock-in. Built around PostgreSQL, Supabase is both stable and extensible.
At its core, Supabase is built on Postgres. Users can leverage auto-generated APIs for direct data querying, and the platform supports SQL, enabling complex queries with ease.
Supabase allows clients to subscribe to changes in the database using the Postgres Changes extension, streaming updates instantly via WebSockets.
Supabase supports multiple authentication providers including OAuth and passwordless options, with role-based access control via a SQL-based rules engine.
Supabase handles various file types — images, videos, and documents — with easy hosting solutions that integrate seamlessly with your backend.
Starting a new project involves creating an account, defining your database schema via the Supabase Dashboard, and managing API requests using your project URL and API key.
Supabase offers Edge Functions (serverless JS/TS), Serverless Functions built on Deno, and Vector Embeddings for AI tool integration with OpenAI and Hugging Face.
Free plan: 500MB database, unlimited API requests. Pro plan: $25/month with 8GB storage and 250GB bandwidth. Self-hosting via Docker is also supported.
Supabase vs Firebase: Supabase wins on complex queries, SQL capabilities, and open-source control. Supabase vs Xano: Supabase provides more flexibility for custom code while Xano offers a visual no-code approach.
