The live preview

Wyber renders your mobile app directly in the browser using react-native-web, so you can interact with it without a phone or simulator.

Using the preview

The preview pane shows your app in a phone frame. You can interact with it like a real app — tap buttons, scroll lists, and navigate between screens. The preview updates automatically after each generation.

App opens on your device
Your app loads on your phone in seconds. Changes you make in Wyber hot-reload on your device automatically — no reinstall needed.

Note: Expo Go imposes some restrictions on native modules. If your app uses custom native code, you'll need a development build — see Exporting to Expo.
