I will integrate firebase or supabase backend into your flutter app
Zain Dev
About this gig
Need a backend for your Flutter app?
Whether you need Firebase or Supabase, I will set it up correctly fully integrated, secure and production-ready.
I cover both platforms and help you choose the right one based on your app's needs.
Firebase is best for mobile-first apps with offline sync and push notifications. Supabase is best for relational data, predictable pricing and SQL-powered logic. Either way, I handle the full integration.
What I integrate:
Firebase: Authentication (email, Google, phone), Firestore database, Realtime Database, Cloud Storage, FCM push notifications, Cloud Functions, Crashlytics, and Firebase Analytics.
Supabase: Auth with Row Level Security, PostgreSQL database, Realtime subscriptions, Supabase Storage, Edge Functions, and OneSignal push notifications.
Every integration is delivered with:
- Clean Riverpod or BLoC state management
- Secure rules and RLS policies configured
- Tested on iOS and Android
- Source code via GitHub or zip file
- Clear documentation of what was set up
Not sure which backend fits your app? Message me I will give you an honest recommendation before you order.

FAQ
Firebase or Supabase, which one should I choose?
It depends on your app. Firebase is better for mobile-first apps that need offline sync, push notifications (FCM), crash reporting and Google ecosystem integration. Supabase is better if your data is relational (SQL), you want predictable monthly pricing or you prefer open-source flexibility.
Can you integrate both Firebase and Supabase together?
Yes. Some apps use Firebase for push notifications and Crashlytics while using Supabase as the primary database, this is a common pattern in 2026. I can set up both and ensure they work together without conflicts.
Will the integration work on both iOS and Android?
Yes. Every integration I deliver is tested on both platforms before delivery. Firebase and Supabase both support Flutter on iOS and Android and I configure platform-specific settings (Google Services JSON, GoogleService-Info.plist) correctly for both.
Do I need to pay for Firebase or Supabase separately?
Both platforms have generous free tiers that cover most small to mid-size apps. Firebase Spark plan is free. Supabase free tier includes 500MB database and 50,000 monthly auth users. I will set everything up on the free tier, you only pay if your app scales beyond those limits.
Can you migrate my existing app from Firebase to Supabase?
Yes. Auth migration, database restructuring (Firestore to PostgreSQL) and storage migration are all services I offer. This is a growing request in 2026 as more developers move away from Firebase's usage-based pricing. Message me with your current setup for a migration estimate.
How do you handle security, are my user's data and auth safe?
Security is built in from the start. For Firebase, I configure Firestore Security Rules so users can only access their own data. For Supabase, I implement Row Level Security (RLS) policies at the database level. I never leave your database open or use insecure default settings.
