The full story
This is a Windows emulator that runs in the browser on WebAssembly and can run actual Win32 EXE files. The maker says it was built with Claude Code and shares a live demo, the source code on GitHub and a page telling the story of how it was made.
The post itself gives few details beyond that, so the story page is the place to look for how it works.
