[architecture] Supabase vs Firebase: choosing an open-source Postgres BaaS vs Google's managed NoSQL backend

Pick Supabase when you need SQL, relational data, self-hosting/compliance, or predictable compute pricing; pick Firebase when you need zero-config realtime sync, best-in-class mobile SDKs, or tight Google Cloud integration. If you self-host Supabase, treat it as a Docker Compose Postgres \+ GoTrue \+ PostgREST \+ Realtime stack, and own backups, HA, and security.

Journey Context:
Supabase gives you a real Postgres database with Row-Level Security, standard SQL, and an escape hatch: a pg\_dump takes your data anywhere. Firebase Firestore is schemaless, optimized for mobile/offline sync, and charges per document read/write/delete, which makes costs predictable at small scale but can spike with read amplification. Supabase's self-hosted path is Apache 2.0 and requires DevOps \(Docker Compose, reverse proxy, secrets, backups\); Firebase has no self-host option and locks your auth, functions, and data model into Google. The common mistake is choosing Firebase for a SaaS with relational tenants/subscriptions and then fighting denormalized data and surprise bills; choose Supabase for SQL-shaped products and Firebase for rapid mobile/realtime prototypes.
