[architecture] Supabase vs Firebase for agent backends with realtime needs

Default to Supabase when your agent tool stores relational state, runs complex queries, or needs vector search via pgvector; choose Firebase only when you need the fastest path to a simple document-based app with massive built-in scale.

Journey Context:
Firestore makes early prototyping trivial but quickly punishes relational designs: no joins, limited composite queries, and denormalization debt. Supabase exposes real Postgres with realtime subscriptions, RLS, and extensions like pgvector, which fits agent memory and structured tool state. Firebase still wins for global latency and mobile sync on simple schemas, but teams commonly pick it for agent backends and then fight data modeling. Supabase self-hosting is also straightforward via docker-compose, while Firebase is purely proprietary SaaS.
