Ubuntu-like sandbox shell in the browser using WebContainer. It supports a live terminal, npm installs, local file import, and optional preview server.
Attach imports a snapshot into WebContainer. Use "Sync Sandbox -> Local Folder" to write changes back to the attached folder when browser readwrite permission is granted.
No files imported.

Available sandbox types: - Flushnet Linux Sandbox - V86 Linux Alpine Demo - V86 Linux Ubuntu Demo Notes: - WebContainer gives you a browser-contained Node.js/Linux-like shell. - Use the terminal to run npm install, node, ls, cat, pwd, etc. - Attach a local folder and it will be mounted into the sandbox immediately. - Use Sync Sandbox -> Local Folder to push file changes back to your attached folder. - Start Preview Server writes a tiny server and exposes it in the iframe. - For real macOS access, use the native Flushnet node instead of the sandbox.
