Arch-based Linux Distribution

CachyOS is a Linux distribution based on the Arch Linux operating system,[4][5] with the end goal of simpler installing and customizing, and improved performance while remaining compatible. CachyOS is also being developed for gaming on Linux,[6] in addition to the aformentioned.[7] CachyOS is developed mainly in Germany.[8] [9]

CachyOS was founded by Peter Jung (ptr1337) and Vladislav Nepogodin (vnepogodin).[1] The name CachyOS originated from the Cachy scheduler,[10] which was the old name of the cacULE scheduler. Peter was involved in testing and developing cacULE, with Hamad.[11] Later, he grew interested in creating an optimized Linux operating system for x86-64-v3 packages. Peter wrote this info on #introduce-yourself section of CachyOS discord server[12] They were later joined by Piotr Gorski (sir_lucjan). [citation needed]

CachyOS[13] has optimisations for performance including: optimised packages specifically compiled for various modern CPU architectures (x86-64-v3, x86-64-v4, Zen4+);[14] custom kernels tuned for performance and stability; advanced CPU scheduler support (including the BORE scheduler[15]).[16]

During development, special emphasis is placed on user-friendliness, performance, and security using pre-configured and optimized packages. In addition, an optimized Linux kernel is provided, as well as a kernel manager for individual settings.[17][18] Furthermore, a hardware detection tool is included, as well as customizable installation options for various desktop environments. KDE Plasma is intended as the default environment. Other features include the included introductory software CachyOS Hello and a package installer. In addition, a “Handheld Edition” is available which, similar to Steam Deck OS, can be used on corresponding devices.[19][20]

Proton is intended for gaming on Linux, in addition to individual solutions. In conjunction with the Steam platform, the software offers a large number of games originally developed for Windows in Linux environments.[21][22]

CachyOS uses its own optimized Linux kernel, which uses the BORE scheduler by default. CachyOS also provides some other schedulers like CFS, PDS, BMQ, TT, and cacULE.[13]

The file systems XFS, Btrfs, F2FS, Ext4, and ZFS are available on CachyOS; XFS is the default. The command-line interface (CLI) installer, written in C++, provides the same functions as the graphical user interface (GUI) installer but it offers more customizing and features than the GUI, and is recommended for advanced users. It also supports configuration, allowing users an automated install.

CachyOS includes tools like CachyOS Hello, Package Installer, Kernel Manager for new Linux users.[13]

Desktop environments

[edit]

CachyOS Nord Theme

CachyOS desktop environments and window managers include CuteFish, i3 window manager, KDE Plasma 5, GNOME, Openbox, LXQt, bspwm, Xfce, Hyprland, UKUI, and Cinnamon.

KDE Plasma is the default CachyOS environment,[23] and includes Nord and Emerald Themes. CachyOS also provides customizing for all other provided desktop environments.[24]

CachyOS Xfce

CachyOS includes security features like a hardened Linux kernel, Hardened-Anonymized-DNSCrypt-Proxy (A toggle for anonymized dnscrypt configuration and use of only dnscrypt servers), Preconfigured DNS Servers using DoH and DoT, Firejail for sandboxing untrusted applications.[25]

CachyOS’s default web browser is Cachy Browser, a software fork of the LibreWolf Browser. It includes added security improvements such as compiling with more secure flags and performance enhancements.[13]

Differences from LibreWolf:[26]

✓ Enhanced security & privacy.
✓ Gentoo patches. Taken from Gentoo’s Firefox.
✓ Dark Reader, ClearURLs, CanvasBlocker added.
✓ Moonlight theme added.
✓ Preset for “Profile Sync Daemon” and Firejail/Firejail(hardened) available.
✓ Custom Rules for CanvasBlocker & uBlock Origin.
✓ Custom branding.

System requirements

[edit]

CachyOS system requirements vary depending on the desktop environment chosen, generally, a PC with 1 GHz processor, 3 GB of random-access memory (RAM), 30 GB of free computer data storage space, such as hard disk drives, and a broadband internet connection (for online installation) are needed.

CachyOS recommends having a x86-64-v3 supported processor, 4 GB of RAM, 50 GB of free disk space and a 50 mbps or better internet connection, for online installation. Newer Nvidia graphics processing units (GPUs) are recommended while old cards are also supported. CachyOS supports systemd-boot and GRUB as the bootloader.[27][25]

CachyOS offers two different installers: a GUI and a CLI. The graphical installer is based on Calamares and allows for both offline and online personalized installations with package selection.

The official CachyOS website provides optical disc image (ISO) images that can be run from a bootable USB flash drive with at least 4 GB of storage space, depending on the ISO image chosen. After preparing the USB device with a tool like Ventoy, they can insert the thumb drive and boot into it from the BIOS. Calamares based GUI Installer will start the installation process.

CachyOS uses a rolling release update model in which new packages are supplied throughout the day. Software packages are updated using the Pacman package manager.

According to PC Games Hardware, CachyOS already achieved a 2.54 percent share of the Linux market on Steam in its first year.[28] In July 2025, it became the most popular distribution on DistroWatch.[29][30][31]
