[architecture] Supabase vs Firebase: choosing a backend-as-a-service stack

Use Supabase when you need real PostgreSQL \(SQL joins, Row Level Security\), open-source portability, and a self-hosting escape hatch. Use Firebase when you need Firestore's offline-first mobile sync, the most mature mobile SDKs, or deep Google Cloud/Analytics integration.

Journey Context:
The core difference is data model and lock-in. Supabase is open-source PostgreSQL with auth, storage, realtime, and edge functions layered on top; you can self-host via Docker Compose and keep standard SQL skills. Firebase is Google's proprietary stack: Firestore NoSQL, Firebase Auth, Cloud Functions, and first-class mobile SDKs. Teams often pick Firebase for rapid mobile prototyping because its offline sync and real-time listeners work out of the box, but they hit friction when relationships grow complex and client-side joins or denormalization become necessary. Supabase gives you real SQL joins, Row Level Security enforced in Postgres, and the option to move off the managed platform; the tradeoff is that its mobile SDKs and offline story are weaker than Firebase's. If you may need compliance-driven self-hosting or relational data, default to Supabase; if you're building a Google-centric mobile app with simple document data, Firebase is still the smoother ride.
