This repository hosts the source code of for https://webvm.io, a Linux virtual machine that runs in your browser.

WebVM is a server-less virtual environment running fully client-side in HTML5/WebAssembly. It's designed to be Linux ABI-compatible. It runs an unmodified Debian distribution including many native development toolchains.

WebVM is powered by the CheerpX virtualization engine, and enables safe, sandboxed client-side execution of x86 binaries on any browser. CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator.

• go to https://webvm.io
• use the provided terminal environment
• have fun!

• go to https://webvm.io
• click "Tailscale Login" in the top right corner
• log in to Tailscale (create an accout if you don't have one)
• if you want to access the public internet, you need an Exit Node. See here for how to set one up. If you just want to access a machine in your Tailscale Network, you don't need it
• depending on your network speed, you may need to wait a few moments for the Tailscale Wasm module to be downloaded
• log in with your Tailscale credentials
• go back to the WebVM tab. You will see your IP address in the top right
• start firing network requests!

Please use Issues to report any bug. Or come to say hello / share your feedback on Discord.

WebVM and CheerpX are compatible with any browser, both Desktop and Mobile, provided support for SAB, IndexedDB, and the device having enough memory.
