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.
Enable networking
- Click "Connect via Tailscale" in the page header.
- 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.
