Live Preview: Open Your Localhost on Your Phone

Live Preview maps your localhost to a URL you can open in the app, so you can watch your site change as your agent works — in phone or desktop viewport.

See your changes as you vibe code

Live Preview shows your website or app updating while your coding agent edits it, without you being on the machine that runs the dev server.

It renders in both phone view and desktop view, so you can check responsive layouts from one device.

Getting your localhost into the app

We open-sourced a live-preview skill that maps your local dev server to a URL you can open in a single tap.

Full setup instructions are in the Live Preview docs. Update the Vicoa mobile app and CLI to the latest version to use it.
