Building separate native apps for iOS and Android means two codebases, two teams and double the maintenance. **Cross-platform frameworks** let you build both from a single codebase. The two leaders are **React Native**, created by Meta, and **Flutter**, created by Google.

## React Native in brief

[React Native](https://reactnative.dev/) lets you build mobile apps with **JavaScript or TypeScript** and React. Your interface is made of real native components, so the app looks and behaves like a platform app. Its newer architecture improves performance and communication with native code.

Most new projects use **Expo**, a framework and toolset that simplifies building, testing and publishing React Native apps, including over-the-air updates.

## Flutter in brief

[Flutter](https://flutter.dev/) uses the **Dart** language and draws every pixel of the interface with its own rendering engine. That gives you precise, consistent visuals on every device and a rich set of built-in widgets.

## Side-by-side comparison

| | React Native | Flutter |
|---|---|---|
| Language | JavaScript / TypeScript | Dart |
| UI approach | Native platform components | Own rendering engine and widgets |
| Look and feel | Matches each platform naturally | Pixel-identical across platforms |
| Code sharing with a React website | High (logic, types, sometimes UI) | Low |
| Ecosystem | Huge npm ecosystem | Growing package ecosystem |
| Hiring | Large pool of JavaScript/React developers | Smaller but growing Dart pool |

## Performance

Both deliver smooth, near-native performance for the vast majority of business apps — forms, lists, maps, payments, chat and media. Flutter's own renderer is excellent for highly custom, animation-heavy interfaces. React Native performs very well for typical apps, especially with its modern architecture and careful list rendering.

For extremely demanding apps — advanced 3D games or heavy real-time video processing — fully native development may still be the right call.

## Development speed

Both offer hot reload, so developers see changes instantly. React Native has an advantage if you already have a **React or Next.js website**: your team can share knowledge, TypeScript types, validation and business logic between web and mobile. See our guide on [MERN stack vs Next.js](/blog/mern-stack-vs-nextjs) for the web side of that picture.

## Features most apps need

Both frameworks support the essentials, either built in or through well-maintained packages:

- push notifications;
- camera, location and biometrics;
- offline storage and sync;
- in-app purchases and payments;
- deep links;
- analytics and crash reporting.

For backends, both pair well with **Firebase** or **Supabase** — compared in [Supabase vs Firebase](/blog/supabase-vs-firebase).

## Testing and releasing

Plan for automated testing (unit tests plus end-to-end tools such as Maestro), beta testing through TestFlight and Google Play testing tracks, and a CI/CD pipeline that builds and submits releases automatically.

## Which should you choose?

**Choose React Native if:**

- you already have a React or Next.js web product;
- you want to share code and developers across web and mobile;
- a native platform look and feel matters.

**Choose Flutter if:**

- you want a highly custom, brand-led design that looks identical everywhere;
- your app has lots of custom animation;
- your team already knows Dart.
