WebVM

WebVM is a fully client-side virtual machine that runs a complete Linux environment directly inside a web browser using WebAssembly and modern web technologies. It is designed to be Linux ABI-compatible, allowing unmodified Linux binaries to run seamlessly without requiring server-side infrastructure. Powered by the CheerpX virtualization engine, WebVM includes an x86-to-WebAssembly JIT compiler, a virtual file system, and a Linux syscall emulator, enabling realistic execution of applications. The system can run a full Debian distribution, including development tools, graphical interfaces, and command-line utilities. One of its most notable features is its serverless design, meaning all computation occurs locally in the browser, enhancing privacy and reducing dependency on external servers. Networking capabilities are provided through integration with tools like Tailscale, enabling connectivity to local or remote environments.

Features

Full Linux virtual machine running entirely in the browser
x86-to-WebAssembly JIT compilation for performance
Compatibility with unmodified Linux binaries and toolchains
Serverless execution with no backend infrastructure required
Virtual filesystem and Linux syscall emulation
