React Native vs Flutter: choosing a cross-platform mobile framework
React Native and Flutter solve the same problem in different ways. React Native, from Meta, uses JavaScript or TypeScript and React components that render real native platform views. Flutter, from Google, uses the Dart language and draws its own widgets with its own rendering engine. Neither is objectively better; they suit different teams and products.
The short answer
Both are mature choices for shipping iOS and Android apps from one codebase. Choose React Native if your team already works in JavaScript or TypeScript and React, or if you want to share logic with a React web app. Choose Flutter if you want pixel-identical custom UI across platforms and are happy for the team to work in Dart.
React Native vs Flutter at a glance
| Criterion | React Native | Flutter |
|---|---|---|
| Language | JavaScript or TypeScript with React | Dart |
| How UI is drawn | Renders native platform components | Draws its own widgets with its own engine |
| Look across platforms | Follows each platform's native controls | Identical by default; platform styles available |
| Code sharing with web | Shares logic, types and skills with React web apps | Flutter web exists but suits app-like UIs more than sites |
| Tooling | Expo simplifies builds, updates and native modules | Strong official tooling and widget library |
| Developer loop | Fast Refresh | Hot reload |
| Native APIs | Large module ecosystem plus custom native code | Plugins on pub.dev plus platform channels |
| Hiring | Draws on the large JavaScript and React talent pool | Smaller but dedicated Dart and Flutter pool |
Choose React Native when
- Your team already knows React, JavaScript or TypeScript
- You have, or plan, a React or Next.js web app and want to share code and types
- You want the app to feel native by using each platform's own controls
- You want Expo's managed builds and over-the-air updates for JavaScript changes
- You expect to hire from the wider JavaScript market
Choose Flutter when
- Your design is highly custom and must look identical on every device
- The app relies on rich animation and a custom design system
- Your team already knows Dart or is starting fresh with no web stack to share
- You also want to target desktop from the same codebase with one UI toolkit
Rendering and how the app feels
React Native maps your components to the platform's own views, so a switch or text input behaves like its native counterpart and picks up platform changes automatically. Flutter paints every pixel itself, which gives total control and consistent results across devices, but platform-specific behaviour has to be matched by Flutter's widgets rather than inherited.
Ecosystem and team fit
For most of my clients the deciding factor is the rest of the stack. When the web app is React or Next.js and the backend is Node.js, React Native lets one team work in TypeScript end to end, sharing validation, API clients and types. Flutter is a strong choice when mobile is the main product and the team is willing to commit to Dart.
Performance in practice
Both frameworks are fast enough for the vast majority of business apps, and React Native's newer architecture has removed many older bottlenecks. Performance problems in either usually come from heavy lists, unoptimised images or too much work on the main thread, not from the framework choice itself.
Frequently asked questions
Is Flutter faster than React Native?
Flutter's own rendering engine gives very consistent animation, and React Native performs well for typical apps, especially on its newer architecture. For most business apps, code quality matters far more than the framework.
Can either framework use native device features?
Yes. Both can access the camera, location, notifications, Bluetooth and more through libraries, and both allow custom native code in Swift, Kotlin or Java when no library exists.
Do I still need separate app store releases?
Yes. Both produce real iOS and Android apps that go through each store's review process. React Native with Expo can push some JavaScript-only updates over the air within store rules.
Still deciding?
Tell me about your product, users and constraints, and I will recommend the option that fits, even if it is not the one I use most.
