The Shift Towards Open-Source Backend Infrastructure
For years, Firebase was the quick prototype choice for web developers. However, vendor lock-in, non-relational database limits, and unpredictable billing forced engineering teams to seek relational alternatives. Enter Supabase.
Key Architectural Advantages
1. Full Relational PostgreSQL Database: Use standard SQL queries, joins, indexes, and custom extensions (pgvector for AI embeddings).
2. Row Level Security (RLS): Secure your database tables directly at the database engine level without writing complex API middleware.
3. Real-time Subscriptions: Listen to database changes over WebSockets for instant live chat, dashboards, and collaborative apps.
4. Self-Hostable: Run Supabase locally via Docker or deploy to your own cloud infrastructure anytime.
