Radium OS

Built from the nucleus up.

Radium OS is a low-level operating system written from scratch by a small crew of femboys.

Not Linux.
Not BSD.
Radium.

Radium OS doesn't borrow a kernel or inherit a userland. It's an independent codebase, built by hand from the lowest level up. We did not make outfits by hand though…

What's inside the core.

Written from zero

Our maid outfits got super sweaty, but we did it. Radium OS is 100% custom code.

Close to the metal

Radium OS lives at the lowest level of the machine, unlike our socks.

Made by femboys

A handful of femboys in programming cat ears, a lot of hours, no corporate roadmap. You can contribute too!

No pre-built .iso.

We cannot build the .iso for you

For security and trust reasons, we do not provide pre-built .iso images. Distributing compiled binaries would require you to blindly trust that the image matches the source code — and that's not something we ask of anyone.

Instead, build it yourself from source. That way you know exactly what's running on your machine. Verify every line. Compile with your own toolchain. That's the Radium way.
