Its own foundation
A UEFI boot manager and a Rust kernel with memory management, scheduling, and drivers.
OPEN SOURCE / ACTIVELY DEVELOPED
A different kind
of starting point.
A new operating system, built from scratch in Rust. Explore what happens when you start from the kernel and build your way up.

AN OPERATING SYSTEM IN PROGRESS✳OPEN SOURCE, FROM THE GROUND UP✳BUILT FOR THE CURIOUS
01 THE IDEA
Not a distribution.
A new foundation.
OSyx is an independent x86-64 operating system with its own bootloader, kernel, file systems, network stack, compositor, and desktop.
It’s an ongoing project for people who want to see how a system comes together — and help shape what it becomes.
Read the overview ↗02 WHAT'S INSIDE
Built layer by layer.
From the first boot to the desktop, each piece has a place.
A desktop called PRISM
A compositor, taskbar, launcher, and native tools for working with files and system settings.
Compatibility in progress
The winrun compatibility layer runs a subset of Windows programs. Support is evolving; not every application works yet.
Connected from within
A native network stack, Ethernet, Wi-Fi support, and signed system updates.
03 WIN PARITY
Windows compatibility,
measured.
How much of the Windows API winrun covers, counted against the export tables of a real Windows install. Nothing here is estimated.
x64 COVERAGE–loading
Coverage is the share of Windows' exports that exist in OSyx as real code (implemented or partial); stubs, error-only functions and unknown never count. Behavioural parity counts only functions exercised by a passing test. How it is measured ↗
Windows is a trademark of the Microsoft group of companies. OSyx is independent and is not affiliated with or endorsed by Microsoft.
04 A CLOSER LOOK
Make yourself
at home.
The real OSyx desktop, tools, and setup — captured from the project.
05 TRY IT OUT
Curiosity looks
good on you.
Try the live system on an x86-64 UEFI computer or explore it in QEMU. OSyx is actively developed, so check the project documentation for current hardware support.

Get the image
Download the live USB image from the latest release.
02
Write & boot
Write the image to a USB drive, then boot it with UEFI and Secure Boot off.
03
Explore OSyx
Try the live desktop. If you choose to install, Setup will erase the disk you select.
Writing an image erases the target USB drive. Check the README before you begin.
06 OPEN BY NATURE
There’s more
to build.
OSyx is free software, made in the open. Follow the work, report an issue, or contribute a little piece of the future.
