If you're choosing between the two
FlutterFlow is the right answer for MVPs, internal mobile tools, and apps where you need to ship to iOS and Android in weeks instead of months.
Custom code is the right answer for production mobile apps that need native performance, complex business logic, deep platform integration (HealthKit, ARKit, custom hardware), or long-term maintainability.
Like Bubble, a common pattern: ship MVP in FlutterFlow, validate, rebuild in custom code once product-market fit is clear.
Genuine strengths of FlutterFlow
FlutterFlow has earned its position as the strongest no-code mobile option:
- Visual builder generating real Flutter code
- Built-in Firebase integration (database, auth, hosting)
- Cross-platform output (iOS and Android) from one codebase
- Speed to market — mobile MVPs in weeks instead of months
- Plugin marketplace for common integrations
- Decent mobile-native output (closer to native than web wrappers)
What custom-coded mobile apps do that FlutterFlow doesn't
FlutterFlow has limits — that's where custom code wins:
- Native performance — true native (Swift/Kotlin) outperforms Flutter for some workloads
- Deep platform integration — HealthKit, ARKit, custom hardware, complex camera workflows
- Complex business logic — FlutterFlow's visual editor hits walls on complex logic
- Long-term maintainability — FlutterFlow apps become harder to maintain as complexity grows
- Cost at scale — FlutterFlow pricing scales with usage; custom apps don't have per-action fees
- Vendor lock-in — FlutterFlow apps export Flutter code but require significant work to fully detach
