A downloadable OS for Windows

BrastinOS is a fake operating system shell that runs as a fullscreen program. It's just a fun project i set for myself to make a functional window environment. BrastinOS comes with a text-edtior, file explorer, image viewer, console, and a way to create you own programs too. It has lots of multitasking capabilities like window snapping and a show desktop feature.

It isn't reallllly useful for anything but it is fun to play around with, and its similar to a fantasy console but not quite.

Looks awesome so far, I can't test it cause I mainly use linux also I agree with the other comments. If this were a real WM I would use it all the time

Thanks! I've been trying to work on Linux and macOS support and hopefully it will release soon. I've never really used linux so its been difficult for me to get everything working

Take as much time  as you need

Love the looks, I wish it could be a full WM..


Thanks :D I really wish it could be a real one too. Maybe I could figure out how to make them


Hi! Great that you’re doing this. I advise don’t jump into OS right away. The next best step for you is to write it as a Desktop Window Manager. That’s the way to make it “real” allowing the user to interact with your UI and dock with their own programs and actual filesystem. Then if you still wish to continue to write the full OS, a component is already done.

Best of luck
