[architecture] Choosing between Supabase and Firebase for a real-time backend

Pick Supabase when you need a portable, open-source PostgreSQL stack that supports row-level security, edge functions, and vendor independence. Pick Firebase only when you want the fastest zero-config path, deep Google ecosystem lock-in, and managed NoSQL scaling without a schema.

Journey Context:
Teams default to Firebase because it ships first-day real-time sync and auth, but they later hit hard limits: no real SQL joins, opaque pricing spikes at scale, and vendor lock-in that makes migration painful. Supabase gives you raw Postgres, so you can later move the database anywhere, use standard ORMs, and self-host if Google kills the product or changes pricing. The common mistake is choosing Firebase for a relational-ish domain and then modeling around its document limits. Supabase's realtime and auth are good enough for most MVPs now, but Firebase still wins for pure mobile-first, offline-sync apps where you accept the tradeoff.
