[architecture] Supabase vs Firebase: which managed backend should an agent choose for a relational app?

Start with Supabase when you need SQL, joins, triggers, Row Level Security, or may outgrow a document model; use Firebase only when your data is genuinely hierarchical and real-time sync is the dominant requirement.

Journey Context:
Firebase's NoSQL model pushes denormalization and client-side joins that become painful as schemas grow. Supabase gives you managed Postgres plus realtime subscriptions, but you trade Google's global edge/Firestore latency for needing to think about connection pooling, migrations, and Postgres extensions.
