Web app preview
See your web app in real time while the AI creates and modifies it, in desktop or mobile view.
Web apps are shown in real time in the “Preview” panel while they are generated and modified.
Options
- “Desktop view” and “Mobile view”: switch between the size of a computer and the size of a phone.
- “Reload preview”: reloads the app.
- “Live demo” / “Open in new tab”: opens the preview in another browser tab.
When you open it, it may take a few seconds (“Starting dev server...”, “Preparing the preview…”).
Preview data is temporary
The preview is only meant to show how your app is progressing. Its database, users and files are temporary: what you create in the preview can be deleted at any time.
If “Build error” appears
It means the web app does not build after a change. Click “Fix with AI” so the AI corrects it. This fix uses tokens.
