Enough With the Fanboy Wars
The React Native vs Flutter debate on Twitter is exhausting. Every comparison is written by someone who clearly prefers one and is looking for reasons to dismiss the other. We use both. We recommend both. And we've shipped enough production apps with each (9 React Native, 6 Flutter) to have an opinion grounded in actual project outcomes, not ideology.
Developer Experience: Flutter Wins, But It's Close
Flutter's developer experience is more polished. Hot reload is faster and more reliable. The widget inspector is excellent. The profiling tools are built into the framework. Everything feels cohesive because it's all from one team (Google's Dart/Flutter team). React Native's developer experience has improved dramatically — the new architecture with Fabric and TurboModules is a genuine step up — but it still feels like a collection of tools from different sources bolted together.
That said, if your team already knows React and JavaScript/TypeScript, the ramp-up time on React Native is practically zero. Dart is easy to learn, but "easy to learn" is still slower than "already know it." For three of our Flutter projects, we budgeted two weeks of Dart onboarding for the team. That's real time and money.
Performance: Flutter Has the Edge for Graphics-Heavy Apps
Flutter renders everything through Skia (now Impeller), bypassing native UI components entirely. This gives it an advantage for custom UI, animations, and graphics-heavy apps. We built a real-time data visualization app in Flutter and the animation performance is buttery smooth at 120fps on modern devices.
React Native renders through native components via a bridge (or JSI in the new architecture). For standard UI — lists, forms, navigation — performance is comparable to Flutter. But for complex custom animations and transitions, you'll often need to drop into native code (Reanimated helps, but has a learning curve). On our last React Native project, we spent about two weeks optimizing a complex animated transition that Flutter would have handled natively.
For what it's worth, both frameworks produce apps that users can't distinguish from fully native apps in normal use. The performance differences only surface in edge cases and graphics-heavy scenarios.
Ecosystem and Libraries: React Native Wins Clearly
React Native has been around since 2015. The ecosystem is massive. For almost any native API integration — payments, maps, Bluetooth, biometrics — there's a mature, well-maintained library. React Native's ecosystem benefits from the broader JavaScript/npm ecosystem, which means you can use thousands of existing JavaScript libraries that don't touch native APIs.
Flutter's ecosystem is growing fast but still has gaps. We've had to write custom platform channels for native integrations that React Native had ready-made libraries for. On one project, integrating a specific Indian payment gateway took two days in React Native (existing npm package) and two weeks in Flutter (custom platform channel because no Dart package existed). For Indian-market-specific integrations — UPI deep links, Aadhaar SDK, DigiLocker — React Native generally has better library support.
When We Recommend Each
React Native: when the team knows React/TypeScript, when you need extensive third-party native integrations, when you want to share business logic with a React web app, and when the app is primarily standard UI (forms, lists, navigation). Flutter: when you need heavy custom UI and animations, when you're building a design-forward consumer app, when cross-platform visual consistency matters more than native look-and-feel, and when you're starting with a team that doesn't have prior React experience.
For the Indian startup market, we lean slightly toward React Native because the JavaScript talent pool is larger, the ecosystem for India-specific integrations is more mature, and most of our clients already have React web apps they want to share code with. But we've been doing more Flutter projects each year, and the gap is narrowing.
