Live browser sandbox · clone · install · run

Run a GitHub app inside an isolated sandbox.

RunRepo now mounts public GitHub source files, installs Node dependencies in WebContainer, starts the project dev server, and opens the live preview without leaving the dashboard.

Sandbox scope

Public GitHub repositories and Node/browser apps. Python services need a server runtime outside the in-browser sandbox.

Use owner/repo or paste a GitHub URL, for example vitejs/vite.

Branch, tag, or SHA.

Optional monorepo folder.

Auto-detected after clone; editable before install.

Must start an HTTP dev server for the live preview.
