PixieOS

Single-file browser OS. Launch it instantly or download the full HTML file.

Launch (new tab) Download (PixieOS.html) Fallback launch (hosted)

For one-click download + launch, place PixieOS.html next to this index.html in the same folder.
If you only want a launcher, you can skip uploading PixieOS.html and rely on the hosted fallback.

Tip: after downloading, you can run PixieOS locally by opening PixieOS.html in a browser. Some features may behave differently under file:// vs https://.
