Comparison

React Native vs. Flutter for Cross-Platform Apps

React Native wins if your team already writes React. Flutter wins for performance, UI consistency, and complex custom interfaces.

Both ship iOS and Android from one codebase. The real difference is in performance ceiling, ecosystem maturity, and developer experience.

Option A

React Native

Pros
  • JavaScript — huge talent pool
  • Strong if your team knows React
  • Good for apps with standard native components
Cons
  • Bridge architecture creates performance overhead
  • Native module fragmentation
  • UI can feel inconsistent across OS versions
Option B

Flutter

Pros
  • Compiled Dart — closer to native performance
  • Pixel-perfect custom UI on every platform
  • Single rendering engine — no OS-specific quirks
  • Strong typing with Dart
Cons
  • Dart — smaller talent pool than JavaScript
  • Larger app binary size
  • Less mature web support
