Supabase

Supabase is an open source Firebase alternative. It provides a dedicated PostgreSQL database, packaged with Authentication, Realtime subscriptions, Storage, and Edge Functions.

When to Use

• Open-Source Firebase Alternative: Complete backend-as-a-service providing PostgreSQL, Auth, Realtime, Storage, and Edge Functions.
• Full Relational PostgreSQL Power: Direct access to real PostgreSQL with extensions (pgvector, PostGIS, pg_cron) and zero proprietary vendor lock-in.
• Row-Level Security (RLS) Authorization: Securing multi-tenant client queries directly at the database layer via SQL security policies.
• Real-Time Database Subscriptions: Subscribing to PostgreSQL insert, update, and delete events over WebSockets from client apps.
