[architecture] Choosing between Supabase and Firebase for a backend

Pick Supabase when your data is relational, you need SQL/ACID, row-level security, predictable pricing, or self-hosting. Pick Firebase when you need fast mobile prototyping, offline document sync, or deep Google Cloud integration and can accept NoSQL denormalization.

Journey Context:
Supabase is Postgres under the hood: real joins, transactions, RLS policies in SQL, no per-request billing, and you can self-host. Firebase/Firestore is a managed NoSQL document store with excellent client-side offline cache and real-time sync, but complex queries require denormalization or multiple reads, pricing is per-document-operation, and there is no self-host option. Teams often start with Firebase for speed and migrate to Supabase when relationships and costs grow.
