Scenario 01
If your team has strong React web developers and wants to share code with the web app…
React Native lets you reuse TypeScript types, domain logic and familiar patterns.
Comparison: React Native (New Architecture) vs. Flutter (Impeller)
React Native vs. Flutter: choosing a cross-platform mobile stack
An assessment of React Native with the New Architecture against Flutter with the Impeller renderer, for teams choosing a cross-platform mobile stack.
Decision framework
Which one fits your situation
Scenario 02
If your app needs heavily custom graphics and identical UI on every platform…
Flutter draws every pixel itself, so the UI looks the same everywhere.
Trade-offs
Side by side
How the two options compare on the dimensions that usually decide this choice.
| Dimension | React Native (New Architecture) | Flutter (Impeller) | Verdict |
|---|---|---|---|
| Code sharing with web | High: TypeScript types, hooks and business logic carry over from React web | Low: Dart is rarely used on the web, so UI code is separate | React Native suits teams already on React |
| Rendering | Native platform UI components through JSI and Fabric | Its own rendering engine (Impeller) draws every pixel | Flutter gives pixel-identical UI across platforms |
| Hiring | A large JavaScript and React talent pool | A smaller, specialized Dart and Flutter community | React Native is easier to hire for |
Questions
Frequently asked questions
Not with the New Architecture. Fabric and TurboModules let JavaScript call native code through JSI instead of serializing messages over the old asynchronous bridge.
Both add a runtime — the Flutter engine, or Hermes plus the React Native runtime — so even a minimal app is several megabytes. Beyond that, size depends on your assets and native dependencies, so compare release builds of a small prototype.
