NautilusOS is a web-based operating system built entirely in HTML, CSS, and JS. Boot it up, log in, and mess around like it’s a real desktop with proxies, games, apps, an app store, windows, a file explorer, taskbar, and more.
NAUTILUS BLOCKED BY YOUR SCHOOL?? DOWNLOAD "index.html" from the NautilusOS-OneFile folder! Open up index.html and you'll have (most*) of Nautilus's features!
*Nautilus Browser is disabled by default in the file, but you may reenable it in the experimental settings under the BIOS (Left shift/F2 during boot), or in the experimental settings under Advanced. The Ultraviolet browser will not work in the file, unfortunately, due to service workers not working in file:/// or file:// url's :(
Make your own vercel.app instance of NautilusOS with this handy button!
You can also do this with Netlify!
You can also deploy NautilusOS in a Github Codespace:
- click on the green code button in this repo
- click on the codespaces tab
- create a new codespace by clicking the "Create codespace on main" button
- navagate to the terminal near the bottom and run
python3 -m http.server 8080 - click the "Make Public" option in the popup that shows up, or go to the Ports tab, right click on 8080, hover on "Port Visiblity" and click "Public"
- click on the Forwarded Address in the Ports tab. it should look something like
https://<your-repo-name>-<random-id>.<your-username>.github.dev - boom! use your temorary link for its full 30 minute lifetime!
*To extend the life of your codespace link visit your profile settings, go to the Codespaces tab, and change the "Default idle timeout" time from 30 minutes to 240 minutes, which is the maximum time.

This is mostly just a fun UI sandbox with no backend or external data storage. It just seemed like the logical next step after Helios Browser.
Everything runs client-side.
Built with just HTML, CSS, and JS (no frameworks, no CDNs except icons/fonts)
