WebVM
Run a full Linux environment in the browser
What it does
WebVM is a virtual Linux environment running in the browser via WebAssembly. WebVM doesn’t require registration. It can be forked, unmodified with no restrictions. WebVM is powered by CheerpX, an x86 virtualization engine in WASM which enables the safe, sandboxed execution of Linux binaries client-side. CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator. Both WebVM and CheerpX are free-to-use for FOSS and personal projects.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
