The models' case: Postgres-based BaaS with mature React Native support via @supabase/supabase-js (works cleanly with Expo), full-text/relational queries, row-level security, auth, storage. The models' main caveat: Realtime and offline-first sync are weaker than purpose-built sync engines. The strongest alternative is Firebase — Deepest native mobile pedigree — first-class RN via @react-native-firebase, battle-tested offline persistence, Firestore realtime, robust Auth with.
