WebVM

This repository hosts the source code 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.

How to: enable networking

Go to https://webvm.io.
Click "Tailscale Login" in the top right corner.
Log in to Tailscale (create an account if you don't have one).
If you are unfamiliar with Tailscale or would like additional information see WebVM and Tailscale.
