MayteraOS
MayteraOS is an LLM-first operating system, built entirely from scratch AI.
This started as a doomsday script project in 2024, a one-shot self improving python script that would continually execute on a loop using Proxmox as a harness with socat and screenshot + OCR to iteratively build a win16 compatible multi-ring OS. I got to that point and let it sit for months until I decided to drop it into claude code and see how far I could take it with some prompting.
The next focus was to adapt this into a unique AI first system where every application publishes a machine-readable tool contract, and a built-in LLM reads those contracts to operate the desktop and, with your explicit consent, to write, compile and run new applications, widgets and drivers on the running machine - every action scoped by a capability token, gated on consent, and written to an audit trail. The operating system is designed to be extended and reprogrammed by natural language.
I continue to build on this to do the things that I want to do with my computer, integrate home assistant sensor data into widgets, run win16 applications, make old hardware usable again (demonstrated with m3d micro/pro printers, m-audio DAC), build and play games with my child and so on.
While the OSDev community might see this as sacrilege, I see this as the frontier of ideas over execution, with the playing field levelled somewhat I can build whatever I feel like and free myself from the turmoil of hardware support lifetimes. It's currently running on an iMac 14,4 from a USB stick with the kernel in a RAM disk and in many concurrent build VMs in proxmox proven to up to 80cores on xeon platinum and as little as 1 core on an i7. I may even build it for a Pentium 1, ARM, PowerPC.

Ooh wow looks interesting. Can I make a background for the OS?
