React Native vs Flutter:
Pick by Rendering and Team Skills
React Native renders real platform views from JavaScript or TypeScript. Flutter draws every pixel itself from Dart. Both ship iOS and Android apps from one codebase, so the right pick depends on your team's language and how custom your UI is.
Which is better for building apps, React Native or Flutter?
Pick React Native if your team knows JavaScript or React and you want your screens built from the platform's own views. Pick Flutter if you want one Dart codebase that draws the same UI everywhere and can also target web and desktop. Both publish normal iOS and Android store apps. Fastshot builds the React Native and Expo version from a text prompt, so you can skip the setup.

React Native vs Flutter: Side-by-Side Facts
Checked against the React Native, Flutter, Dart and Expo documentation in November 2026.
| Factor | React Native | Flutter |
|---|---|---|
| Language | JavaScript or TypeScript with React | Dart |
| How the UI is drawn | React components map to native host views, so the app uses the same platform UI as any other app | Flutter's own engine draws every widget. Impeller is the default renderer on iOS and on Android API 29 and up |
| Release runtime | Hermes is the default engine. It compiles JavaScript to bytecode at build time | Dart compiles ahead of time to machine code for release. Development runs in a VM with stateful hot reload |
| Architecture status | The New Architecture has been the default since React Native 0.76. Release 0.88 shipped on October 19, 2026 | Impeller has been the default on iOS and Android API 29+ since Flutter 3.27, and on macOS and Linux as of 3.47 |
| Platforms from one codebase | Android and iOS, plus web through Expo | Mobile, web, desktop and embedded |
| Calling native code | Turbo Native Modules and Fabric components, written in Swift, Objective-C, Java, Kotlin or C++ | Platform channels in Kotlin, Java, Swift or Objective-C, plus Pigeon, FFIgen and JNIgen |
| Package source | npm and the React Native Directory | pub.dev |
| Known apps | Facebook, Instagram, Amazon Kindle, Microsoft apps, all Shopify mobile apps | Google Pay, NotebookLM, Google Earth |
| Store accounts | Apple Developer ($99 a year) and Google Play ($25 one-time) | Apple Developer ($99 a year) and Google Play ($25 one-time) |
Pick React Native If Your Team Writes React
React Native apps are written in JavaScript or TypeScript with React. Each component becomes a real platform view, so a text input, a scroll view or a switch is the same control a Swift or Kotlin app would show. The React Native homepage sums it up as "written in JavaScript, rendered with native code".
Since React Native 0.76 the New Architecture is the default. It gives synchronous layout reads and the concurrent React 18 renderer. Hermes, the default engine, precompiles your JavaScript to bytecode in release builds, which the docs say improves start-up speed on a device.
The ecosystem is npm. A web team can reuse TypeScript types, validation code and API clients, and Expo adds file-based routing and cloud builds on top. Choose it when hiring from the React talent pool matters, or when your app should follow each platform's own look without extra theming.
Pick Flutter If You Want One Renderer on Every Screen
Flutter apps are written in Dart. Flutter does not hand your widgets to the platform. Its own engine draws them, and Impeller compiles its shaders at engine-build time so they are not compiled while the app runs. The result is the same pixels on every device.
That suits a strongly branded interface or custom animation. Flutter's own site lists mobile, web, desktop and embedded targets from a single codebase, so one team can also ship Windows, macOS and Linux apps.
The trade-off is the language and the package source. Dart is new to most web teams, and plugins come from pub.dev rather than npm. If you already run a Flutter team, the Flutter app development guide covers what to build with it.
What Most Apps Need Either Framework Works
Most apps are lists, forms, sign-in, payments, push notifications and a few device features. Both frameworks cover all of that, and both produce ordinary store binaries. You publish them with the same Apple Developer account ($99 a year) and Google Play account ($25 one-time).
That leaves three real questions. Which language does your team already write? Do you need one custom-drawn interface on every platform? Do you need web or desktop from the same code? If the answer to the first is JavaScript, choose React Native. If the second or third is yes and Dart is fine, choose Flutter.
Where Fastshot Fits: The React Native Side, Built for You
Fastshot generates React Native + Expo apps for iOS and Android from a text prompt. The first version arrives in about 5 to 7 minutes, with a live browser preview and Expo Go by QR code. It builds the APK, AAB and IPA on its own machines and publishes to the App Store and Google Play with your own developer accounts. You own the source code.
How to Test the Choice in One Afternoon
Pick your hardest screen
Choose the screen with the most custom UI or device access: a camera view, a map with markers or a long image feed. That screen shows the real difference between the two renderers.
Look up your three key packages
Search pub.dev for Flutter and the React Native Directory for React Native. Note which payment, map and analytics packages have maintained Android and iOS support.
Run a release build on a real phone
Hermes bytecode in React Native and ahead-of-time machine code in Flutter only apply to release builds. Debug builds on either side tell you little about speed.
Count who can debug it
List the people on your team who can read the language and tools of each stack. The framework your team can fix at 2 a.m. is the one to ship.
Frequently Asked Questions
Does Flutter use Dart?
Yes. Every Flutter app is written in Dart. Dart has a VM for development with stateful hot reload and an ahead-of-time compiler that produces machine code for release builds.
Which language does React Native use?
JavaScript or TypeScript, written as React components. Native code in Swift, Objective-C, Java, Kotlin or C++ only comes in when you add a native module for a platform feature.
Is ReactJS the same as React Native?
No. ReactJS renders to the browser DOM. React Native uses the same component model and hooks but renders to native iOS and Android views. You can share ideas and some logic code between them, but not the UI components.
Is Flutter still relevant in 2026?
Yes. The Flutter docs show Impeller as the default renderer on iOS, on Android API 29 and up, and on macOS and Linux as of Flutter 3.47. The Flutter showcase also lists Google Pay, NotebookLM and Google Earth.
Is React Native losing popularity?
The project is shipping steadily. React Native 0.88 came out on October 19, 2026, the New Architecture has been the default since 0.76, and Meta, Microsoft and Shopify appear in the React Native showcase.
Which famous apps use React Native?
The React Native showcase lists Facebook, Instagram, Amazon Kindle and several Microsoft apps. It also says all mobile apps at Shopify are built with React Native.
Can I build a React Native app without writing the code myself?
Yes. Describe the app to Fastshot and it writes the React Native and Expo project, runs it in a live preview and builds the store files. You keep the source code and can export it as a zip or to GitHub.
