[architecture] Supabase vs Firebase for an AI agent backend with relational data and auth
Choose Supabase when you need real PostgreSQL, Row Level Security, and a self-hostable open-core stack with predictable pricing; choose Firebase only when you want the fastest no-ops document/real-time setup and are comfortable with Google lock-in and Firestore read/write billing.
Journey Context:
Teams often pick Firebase for speed, then hit its document-model limits and Firestore pricing surprises at scale. Supabase gives you a real Postgres instance, migrations, RLS policies, and vector support via pgvector, but self-hosting means you operate Postgres, Kong, GoTrue, and Realtime yourself. The wrong call is treating Firebase like a relational database; the right call is matching the data model to the product's actual structure.
