Expo Go / Run on Phone
The Preview button in the RapidNative editor lets you run your app on a real phone in seconds. It generates a QR code that anyone can scan with Expo Go — no build process, no deployment needed.
How it works
Open your project in the RapidNative editor
Click the "Preview" button in the editor header
A QR code is generated for your project
Open Expo Go on your phone and scan the QR code
Your app loads and runs live on your device instantly
Sharing with others
You can share the QR code with anyone — teammates, clients, or stakeholders. As long as they have Expo Go installed on their phone, they can scan it and preview the app without needing access to RapidNative.
- Download Expo Go from the App Store (iOS) or Google Play (Android)
Web preview alternative
If you don't have Expo Go installed, RapidNative also offers a browser-based preview powered by browser-metro, an open-source bundler for Expo projects that runs directly in your browser. You can also try it standalone at reactnative.run.
Why it's valuable
- Test your app on a real device with zero setup
- Share a live preview with clients or teammates instantly
- No build process or deployment required
- Works on both iOS and Android via Expo Go
