We've shipped production apps in both Flutter and React Native. Here's the real comparison — not the one from a framework's own marketing page.
Performance
Flutter wins here. It compiles to native ARM code and renders using its own engine (Skia/Impeller). Animations are buttery smooth. React Native bridges JavaScript to native modules, which adds overhead — though the New Architecture (JSI) has improved this significantly.
Developer Experience
React Native wins if your team knows JavaScript/TypeScript. You'll be productive immediately. Flutter uses Dart, which is a learning curve but genuinely enjoyable once you get it.
Ecosystem & Libraries
React Native has a larger third-party ecosystem (npm + the React community). Flutter's pub.dev is growing fast but still smaller. For most use cases, both have what you need.
UI Consistency
Flutter gives you pixel-perfect identical UI on iOS and Android (it draws its own widgets). React Native uses native components, so there can be small platform differences.
Our Recommendation
At Sundram Tech, we use both — we pick based on the project. If you're starting fresh, we're happy to advise. Book a call.
