What is WebVM?
It's designed to be Linux ABI-compatible. In demo, 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.
