- LinuxOnTab is a browser-based Linux desktop that boots a real x86 kernel and Alpine userland using WebAssembly and v86 emulator, requiring no installation or sign-up.
- It offers full networking via an optional WebSocket backend, allowing TCP egress and port tunneling for SSH, SCP, SFTP, and rsync, with persistent storage via IndexedDB snapshots.
- The tool is sandboxed in the browser, works offline after caching, supports the Alpine package ecosystem, and is ideal for disposable shells, demos, and teaching.
- Key features include Picture-in-Picture mode for floating terminals, URL-driven configuration for demos, and peer-to-peer file sharing via Nostr relays.
