The developer branch of this repository is always the most updated one, with the newest commits and features, check it out.
There is also a website that gets updated once in a million years (doxygen), I updated it last at: December 16th, 2025. link that will hack your computer
MatanelOS is a 64-bit SMP Compatible Operating System built from scratch, inspired by Windows kernel architecture. It features preemption, IRQLs, DPCs, paging, dynamic memory (PFN DB, pools), and a fully-fledged VFS (currently FAT32), and a scheduler that supports multiprocessing. This project is for educational purposes and low-level OS experimentation.
