[architecture] Supabase vs Firebase: which managed backend should I pick for a new agent-facing service?

Choose Supabase when you want a real Postgres database you can self-host, query with SQL, and keep schema ownership. Choose Firebase when you need first-class offline/sync, real-time NoSQL, and serverless scaling without schema design.

Journey Context:
Teams often pick Supabase because it looks like "open-source Firebase," but the two diverge quickly. Supabase gives you a real PostgreSQL instance, row-level security, and the option to self-host everything, which is powerful for relational data and compliance but adds ops overhead \(migrations, backups, connection pooling\). Firebase \(Firestore \+ Auth \+ Functions\) is managed end-to-end, has unmatched client SDKs for real-time sync, and scales without you touching a server, but it locks you into a proprietary document model and pricing can explode with egress or frequent reads. The common mistake is building a relational app in Firestore or expecting Firebase-level zero-ops from self-hosted Supabase.
