( summary )

Both cross-platform, different strengths.

React Native rewards React teams with the JavaScript ecosystem. Flutter shines with consistent custom UI and strong tooling.

Flutter

Dart + own rendering engine. Great for consistent custom UI, animations, and a fast build experience across platforms.

React Native

React + JavaScript, native components. Great when your team knows React and you want the large JS ecosystem.

Questions buyers ask

What is the difference between Flutter and React Native?

Flutter is Google's UI toolkit that compiles to native code with its own rendering engine. React Native lets you build mobile apps with React and JavaScript, rendering native components. Both are cross-platform so one codebase can ship to iOS and Android.

Which has better performance: Flutter or React Native?

Flutter often feels more consistent for complex animations because its own engine draws every pixel uniformly. React Native performance is generally excellent, and the modern New Architecture narrows the gap.

Which is easier to learn?

If you know React, React Native is the friendlier pick. If you're new to both but know a C-family language, Flutter's Dart is approachable thanks to strong tooling and documentation.

When should I choose Flutter?

Choose Flutter when you want consistent custom UI, strong animation, and a single codebase with a fast build experience across iOS, Android, and even web and desktop.

When should I choose React Native?

Choose React Native when your team already knows React, you want to reuse web knowledge, or you need the large JavaScript ecosystem and native library access.

Can Udaan build a cross-platform app?

Yes. We deliver Flutter and React Native apps across iOS and Android, and can recommend the best fit after a short discovery.
