React Native vs Flutter: Which Cross-Platform Framework Should You Choose?

Building separate iOS and Android apps means two codebases, two teams and features that drift apart. Cross-platform frameworks solve that by shipping one codebase to both platforms, and two of them dominate: Meta's React Native and Google's Flutter.

Both are mature and power apps used by millions of people. The right choice depends on your team, your product and your existing technology rather than on which framework is "better". Our mobile app development team builds with both; this is how we help clients choose.

The short version

	React Native	Flutter
Language	JavaScript / TypeScript	Dart
UI rendering	Native platform components	Its own rendering engine
Look and feel	Follows each platform by default	Identical on every platform
Web code sharing	Strong with React and Next.js	Limited
Hiring pool	Very large (JavaScript developers)	Growing, smaller

React Native

React Native lets developers write components in TypeScript using React, and renders real native UI elements on each platform. Its New Architecture improved performance and interoperability with native code, and tools such as Expo make setup, builds and over-the-air updates straightforward.

export function Greeting({ name }: { name: string }) {
  return (
    <View style={styles.card}>
      <Text style={styles.title}>Hello, {name}</Text>
    </View>
  );
}

Choose React Native when

• Your team already works in JavaScript, TypeScript or React.
• You have a React or Next.js website and want to share logic, types and developers.
• You want the app to feel native on each platform by default.

Flutter

Flutter uses the Dart language and draws its interface with its own rendering engine, so an app looks exactly the same on every device. Its widget library is extensive, and hot reload makes UI work fast.

class Greeting extends StatelessWidget {
  const Greeting({super.key, required this.name});
  final String name;

  @override
  Widget build(BuildContext context) {
    return Card(child: Text('Hello, $name'));
  }
}

Choose Flutter when

• The design is highly custom and brand-led, with rich animation.
• Pixel-identical UI across iOS and Android matters more than platform conventions.
• You are starting fresh, with no existing JavaScript codebase to share.

What about performance?

For forms, lists, dashboards, e-commerce and most business apps, both frameworks deliver smooth performance, and users will not notice a difference. Performance problems almost always come from how an app is built: oversized images, unoptimised lists and unnecessary re-renders. Graphically intensive apps can lean towards Flutter's rendering model.

When neither is the answer

Fully native development in Swift and Kotlin is still the right choice for apps built around platform-specific capabilities: advanced camera processing, augmented reality, complex background work or deep integration with the newest OS features on release day. Both cross-platform frameworks can call native code, but if most of the app is native work, build it natively.

How to decide

1. Start with your team: the framework your developers know will ship faster.
2. Look at your existing stack: a React website points towards React Native.
3. Look at your design: heavily custom, animated interfaces point towards Flutter.
4. Check the native features you need and confirm well-maintained packages exist.
