cachyfetch

A fast and minimal system information fetcher written in Zig and built with CachyOS in mind.

Features

• CachyOS ASCII logo with compact colored output
• User/host, OS, kernel, uptime, and package count
• Shell and terminal detection
• DE/WM detection for KDE Plasma, GNOME, Hyprland, Sway, and niri
• WM theme, GTK/KDE theme, icons, font, and cursor detection
• CPU, GPU, monitor, memory, swap, disk, locale, and local IP info
• Progress bars for memory, swap, and disk usage
• 16-color palette preview

Quick start

Build

zig build -Doptimize=ReleaseFast

Run

zig build run

Or run the built binary directly:

./zig-out/bin/cachyfetch

Install

zig build -Doptimize=ReleaseFast
sudo install -Dm755 zig-out/bin/cachyfetch /usr/local/bin/cachyfetch

Requirements

Build

• zig 0.15.0 or newer

Runtime

These tools are optional and are only used when available:

• pacman for package counting
• lspci from pciutils for GPU detection
• ip from iproute2 for local IP detection
• gsettings from glib2 for GTK/GNOME theme, icon, and font detection

Notes

• cachyfetch is Linux-only and reads data from /proc, /sys, desktop config files, and optional system utilities.
• KDE Plasma theme information is read directly from files in ~/.config.
• When a command or desktop-specific source is unavailable, the corresponding field falls back to unknown.
