React Native vs Flutter: Which Should You Choose?
Both are mature, production-ready choices, and either can build a fast iOS and Android app. Pick React Native if your team knows JavaScript or TypeScript, you want platform-native UI controls, or you plan to share code and people with a React web app. Pick Flutter if you want pixel-identical custom design on every platform, strong built-in UI widgets, and you are comfortable hiring for Dart.
- React Native uses JavaScript or TypeScript and renders real iOS and Android components; Flutter uses Dart and draws every pixel itself.
- React Native now runs entirely on its New Architecture, and its docs recommend starting new projects with a framework like Expo.
- Flutter's Impeller renderer is the default on iOS and modern Android, which gives smooth, consistent animation.
- Hiring and code sharing with an existing web team usually decide it more than raw performance does.
- Both have large ecosystems, but check that the specific plugins your app needs are actively maintained.
At a Glance
| Factor | React Native | Flutter |
|---|---|---|
| Language | JavaScript or TypeScript (React) | Dart |
| How UI is rendered | Real iOS and Android components | Draws its own UI with Impeller |
| Look across platforms | Follows each platform's conventions | Identical unless you adapt it |
| Recommended starting point | A framework such as Expo | Flutter SDK and its widget library |
| Official targets | iOS, Android; web and desktop via add-ons | iOS, Android, web, Windows, macOS, Linux |
| Code sharing with a React website | Strong | Limited |
| Custom, animation-heavy design | Good | Excellent |
| Backed by | Meta and community | Google and community |
Choose React Native if your developers know JavaScript or React, you want standard platform UI, or you want to share code with a React web app. Choose Flutter if a highly custom, brand-driven interface that looks identical everywhere matters most, or you want one toolkit for mobile, web and desktop.
The Core Technical Difference
The two frameworks solve the same problem in opposite ways.
React Native lets you write the app in JavaScript or TypeScript using React. Your components map to the platform's own UI elements, so a switch on iOS is an iOS switch and a list on Android scrolls like Android. Since version 0.82 React Native runs entirely on its New Architecture, which replaced the old asynchronous bridge with a more direct way for JavaScript and native code to talk. The official docs now recommend building new apps on a framework, with Expo as the main example, which handles builds, updates, routing and many device APIs for you.
Flutter uses Google's Dart language and does not use platform UI controls at all. It draws the entire interface itself with its Impeller rendering engine, which is the only renderer on iOS and the default on Android API 29 and later. That gives you exact visual control and identical results across devices. Flutter ships its own Material and Cupertino widget sets so apps can still follow platform conventions when you want them to.
In day-to-day development the experience is similar. Both offer hot reload, so developers see changes in a second or two without restarting the app, and both have solid tooling in VS Code and Android Studio. React Native projects lean on the npm ecosystem and TypeScript tooling; Flutter projects lean on Dart's strong typing and Flutter's built-in widget catalog, which means fewer third-party UI libraries to evaluate.
Performance in Practice
For the typical business app (lists, forms, maps, payments, chat, dashboards), both deliver smooth performance when built well. Most slow apps in either framework are slow because of oversized images, unoptimized lists or too many network calls, not the framework.
Flutter has an edge for animation-heavy or highly custom interfaces, because it controls every frame and does not depend on platform widgets. React Native has an edge when the goal is to feel exactly like a standard platform app, because it uses the platform's own controls and picks up OS-level look-and-feel changes automatically.
Team, Hiring and Code Sharing
This is usually the deciding factor for small and mid-sized businesses.
- React Native fits teams that already work in JavaScript, TypeScript or React. Logic, validation rules, API clients and sometimes design tokens can be shared with a React web app, and web developers can pick it up quickly.
- Flutter requires learning Dart, which is approachable for developers with Java, Kotlin, Swift or C# backgrounds. Teams that commit to it often like that one language and toolkit covers mobile, web and desktop.
Both talent pools are large. React Native draws on the broader JavaScript market. Flutter specialists are widely available but you are hiring for a narrower skill set, so check local and remote availability before committing.
A practical test: ask who will maintain the app in two years. If the answer is a web agency or an internal developer who already writes React, React Native lowers that long-term cost. If you are hiring a dedicated mobile team or vendor that specializes in Flutter, the language question largely disappears.
Web, Desktop and Other Platforms
Flutter officially targets iOS, Android, web, Windows, macOS and Linux from one codebase. Its web output is best suited to app-like experiences behind a login rather than content pages that need to rank in search.
React Native focuses on iOS and Android. Expo adds web support through React Native for Web, and Microsoft maintains React Native for Windows and macOS. If you already have, or plan, a separate React website, many teams simply share code between the React web app and the React Native mobile app rather than forcing one UI to fit both.
Design is the other angle. If your brand calls for a distinctive interface with custom transitions, Flutter makes that natural. If you want the app to feel like a standard iPhone or Android app, with system menus, date pickers and gestures users already know, React Native gets you there with less custom work. Neither is wrong; they reflect different product priorities.
Ecosystem, Plugins and Long-Term Risk
Both frameworks are backed by major companies (Meta for React Native, Google for Flutter) and both have large package ecosystems: npm for React Native and pub.dev for Flutter. The quality varies package by package, so before choosing, list the integrations your app needs (payments, maps, Bluetooth, health data, analytics, a specific SDK from a partner) and confirm each has a maintained library or official SDK for your framework.
Over-the-air updates are another practical difference. With React Native and Expo, teams can push JavaScript-only fixes to users without a full store release, within Apple's and Google's rules. Flutter apps generally ship changes through the stores. For context on whether you need either framework at all, see native vs cross-platform and our app development overview.

Related Questions
Which is cheaper to build with?
Neither is inherently cheaper. Cost depends on scope and your team's existing skills. A team fluent in React will build faster in React Native; a team experienced in Flutter will be faster there. Ask any vendor which framework they have shipped the most production apps in.
Is Flutter or React Native better for SEO-friendly web pages?
Neither is ideal. Flutter web renders to a canvas-style output that suits logged-in app screens, not search-ranked content. For public marketing pages, use a normal website and keep the framework for the app itself.
Can I migrate from one to the other later?
Only by rewriting the app's UI and logic layers. Your backend, APIs and designs carry over. Because migrations are costly, it pays to prototype one or two key screens before committing.
What is Expo and do I need it?
Expo is an open-source framework and toolset on top of React Native that handles project setup, builds, routing, device APIs and over-the-air updates. React Native's own docs recommend a framework like it for new apps, and most new projects use it.
