[architecture] Supabase vs Firebase: which backend should an AI agent project actually choose?

Pick managed Supabase when you need Postgres relations, RLS, and SQL tooling; pick Firebase only when you need Firestore's offline sync, mobile-first SDKs, and Google's ecosystem. Self-host Supabase only if compliance demands it, because platform features \(branching, PITR, managed backups, vector/ETL\) are stripped from self-hosted.

Journey Context:
Teams often default to Firebase for speed, then hit walls when agent data needs joins, migrations, or complex auth rules. Supabase gives you real Postgres with Row Level Security and a managed auth layer, but its self-hosted Docker Compose path shifts all backup, HA, scaling, and security patching onto you. Firebase Firestore scales writes but queries become expensive and limited. The real trap is trying to self-host Supabase to save money: you lose the features that justify Supabase over plain Postgres, and you still carry full ops overhead. Use managed Supabase for agent backends with relational data; use Firebase for mobile/sync-first apps where query expressiveness matters less.
