React Native Online IDE - Build Mobile Apps in Your Browser

Setting up React Native locally is not a quick process. You need Node.js, Watchman, Xcode or Android Studio (or both), and then there is the emulator configuration. It is a lot of moving parts before you write a single line of app code.

OneCompiler Studio sidesteps all of that.

A full environment, not a snippet runner

Studio gives you a complete cloud IDE for React Native development. You get a VS Code-like editor, a file tree, a terminal with full shell access, and npm at your fingertips. The workspace comes pre-configured with Expo, so you can start building immediately without worrying about native toolchain setup.

Here is what your React Native Studio workspace includes:

  • An Expo-based React Native project, ready to run
  • Hot reload so your changes appear on the device preview as you type
  • Terminal access for installing packages via npm install
  • 2 vCPUs and 4 GB of memory on a dedicated VM
  • The whole thing launches in about a minute

Why Expo in the browser makes sense

Expo is already the recommended way to start a React Native project. It abstracts away most of the native build complexity. Running it inside Studio takes that a step further: you do not need Xcode, you do not need Android Studio, and you do not need a physical device plugged in.

You write your components, save, and see the result. The development loop is the same as working locally with Expo, just without the local dependencies.

What you can actually build

Because this is a real environment with terminal access, you are not limited to toy examples:

  • Multi-screen apps. Set up React Navigation, create a tab navigator, add a stack. The file tree keeps everything organized.
  • API-connected apps. Run npm install axios in the terminal and start fetching data from a REST API or GraphQL endpoint.
  • Styled apps. Use NativeWind, styled-components, or just the StyleSheet API. Install whatever you prefer.
  • Apps with state management. Zustand, Redux Toolkit, Jotai. Pick one, install it, wire it up.

This is the same workflow you would follow on your own machine. The difference is you skip 30 minutes of environment setup.

When to use Studio vs. the code editor

OneCompiler's React Native editor is good for testing a single component or trying out a quick idea. No file system, no terminal, just code and output.

Studio is for when you need the full picture. Multiple files, package installs, project structure, routing. If you are building something that has more than one screen, you want Studio.

Who this is for

You are learning mobile development and do not want to spend an afternoon configuring Android Studio. You are on a Chromebook or a locked-down work laptop. You want to prototype a mobile app idea before committing to a full local setup. Or you are running a workshop and need every participant to have an identical, working environment in two minutes.

All of those are good reasons to use a cloud IDE instead of fighting with local tooling.

Try it

Open OneCompiler Studio for React Native and you will have an Expo project running in about a minute. No installs, no emulator setup, just code.
