How CodeLab works.

A multi-file workspace, automated preview testing, and a sandboxed browser runtime.

WORKFLOW

The model tests its changes in the preview

CodeLab searches your project files, applies edits, and opens the preview to check the browser console for JavaScript errors before finishing the turn.

File search Console inspection Preview capture Split-screen view
PROJECT EXPLORER

Files, assets and local storage

Manage project folders (js/, assets/), HTML/CSS/JS files, audio, and SQLite databases alongside an integrated terminal.

Assets & audio Integrated terminal
WEBVIEW RUNTIME

Sandboxed WebView with fullscreen mode

Mounted over a virtual HTTPS domain so ES modules, fetch(), WebAudio, and Canvas APIs work without file:// CORS restrictions.

MODELS & EXPORT
