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

Pick Supabase when you need a relational model, SQL joins/ACID, predictable pricing, and the option to self-host. Pick Firebase for fast mobile prototypes, first-class offline sync, real-time collaboration, or when you are already embedded in Google Cloud.

Journey Context:
Both promise a managed backend, but Firebase is a proprietary Google stack around Cloud Firestore \(NoSQL documents\) with usage-based per-read/write pricing that can spike unexpectedly. Supabase is open-source Postgres with auto-generated REST/GraphQL APIs, Row-Level Security, and no per-request charges. A common trap is using Firestore for relational SaaS data: you end up denormalizing and running client-side joins. Conversely, choosing Supabase for a simple mobile app that needs offline cache and zero-config real-time sync adds unnecessary schema work. The migration path from Firebase to Supabase is documented, but it is easier to decide at the start.
