Appwrite vs Firebase vs Supabase — Choosing a Backend for Your Flutter App

FlutterInit supports Firebase, Supabase, and Appwrite as first-class backend overlays. The right pick depends on hosting, database preference, and ecosystem — not which logo looks nicest in a slide deck.

Comparison (Flutter-focused)

How FlutterInit treats them equally (almost)

Each backend gets:

• AppConfig initialization
• An AuthService implementation
• Dotenv keys documented in SETUP.md
• The same repository → presentation path in your chosen architecture

They are not feature-identical products. Don’t expect Firestore APIs from Supabase.

Pick one

• Firebase — mobile Google stack; see Firebase Auth wiring
• Supabase — SQL + Riverpod; see Supabase + Riverpod
• Appwrite — self-host / OSS; see MVVM + Provider + Appwrite or Bloc + Clean + Appwrite

Switching later

Domain repositories make swaps cheaper. Still budget real work for data models and security rules — FlutterInit won’t migrate your production data.

Choose a backend on /create and generate auth before you write feature screens.
