Introduction

Oniomarchy is a cybersecurity/pentest-oriented Linux distribution based on Omarchy (Arch Linux + Hyprland + Quickshell), positioned as an alternative to Kali Linux and Parrot OS.

The name is “oni” (鬼, Japanese for demon/ogre) combined with “Omarchy”.

Oniomarchy installs as an overlay on top of a stock Omarchy system: a single install script adds pentest tooling, menu entries, and services without touching any Omarchy-owned files.

Oniomarchy is currently in active development. This site will grow alongside the project.
