Performance-First Linux, Built on Arch
CachyOS ships every package optimized for your CPU - compiled with x86-64-v3/v4 and Zen4 instructions, LTO, and PGO - on top of a custom kernel with the tuned EEVDF scheduler. The result: a noticeably faster Arch Linux experience with the same rolling-release flexibility you expect.

Why CachyOS Is Different
Most Linux distributions ship generic binaries. CachyOS rebuilds the stack — from kernel to packages — with modern CPU optimizations, delivering measurable performance where it matters.
CPU-Optimized Package Repository
Every package is compiled with x86-64-v3, x86-64-v4, and Zen4 instruction sets plus LTO. Core packages receive additional PGO and BOLT optimization — no manual rebuilds required.
Advanced Kernel with Scheduler Choice
The linux-cachyos kernel ships with tuned Scheduler for responsive interactivity, plus options for BORE, sched-ext, BMQ, and RT. All kernel builds are CPU-optimized with x86-64-v3/v4, Zen4 and LTO.
Install Your Way
Two installers to match your workflow: a graphical Calamares-based installer for a guided setup, or a CLI installer for full control over every detail.
17+ Desktop Environments & Window Managers
Choose from KDE Plasma, GNOME, COSMIC, Hyprland, Sway, Niri, i3, XFCE, and more. Pick your preferred environment during installation — every option is fully supported out of the box.
Help Us Keep CachyOS Free
CachyOS is built and maintained by a small team of open-source contributors. Your support helps cover infrastructure costs and keeps development going.
