Supabase gives you a real PostgreSQL database with row-level security and open-source freedom. Firebase offers a beginner-friendly NoSQL database with excellent Google ecosystem integration and offline mobile sync. Your choice depends on whether you prefer SQL or NoSQL, and whether open-source matters to you.
Supabase is better if you want SQL and open-source; Firebase wins for mobile apps and Google integration.
Open-Source Backend

By Google
Google's app platform that gives you a NoSQL database (Firestore), authentication, hosting, cloud functions, and analytics — popular for mobile and web apps.
