About anuraOS
anuraOS is a browser-based operating environment and development environment with graphical Linux emulation. Its visual design is based on ChromiumOS, and the Linux emulation is based on the v86 project. According to its repository, it runs entirely locally in the browser, and a demo is available.
The project mainly targets Chromium, though the authors state it should work on most browsers. It is described as a proof-of-concept of what is possible on the modern web rather than a finished product, but the authors note it is useful in many practical cases and as an educational tool. Building it from source requires several tools, including Node.js 24 or later, Docker, and an x86 Linux PC for some steps. It will not build on Windows, and the README recommends a Linux virtual machine or WSL instead.
