[architecture] Supabase vs Firebase: which backend-as-a-service should I choose?

Choose Supabase when your data is relational, you need SQL joins/ACID, Row-Level Security for multi-tenancy, predictable tiered pricing, pgvector for AI, or a self-host/exit path. Choose Firebase when you are building mobile-first apps that need first-class offline sync, deep Google Cloud integrations \(Analytics, FCM, Crashlytics\), or fastest prototype velocity.

Journey Context:
The choice is really Postgres vs Firestore. Supabase gives you a real PostgreSQL database with auto-generated REST/GraphQL, RLS policies in SQL, and the ability to pg\_dump your way out; Firebase is a proprietary NoSQL document store with per-read/write billing that can spike unexpectedly and no real migration path. Teams often start on Firebase for speed, then hit the wall when relationships, complex queries, or cost predictability matter. Supabase requires SQL fluency and has less mature mobile SDKs; Firebase wins on offline-first mobile and Google ecosystem lock-in. If you may outgrow a BaaS, Supabase's open-source portability is the safer long-term bet.
