Omarchy

Omarchy is a Linux distribution created by David Heinemeier Hansson (DHH) and developed in the basecamp/omarchy repository under the MIT license. It ships a pre-configured desktop with chosen defaults ("omakase"): themes, a top bar, terminals, editors, development tools and a full manual. The project describes itself as an "agentic" OS, in which a coding agent is set up on first boot and can be used to diagnose crashes, fix problems and build apps, plugins and themes.

Installation is done by writing an ISO to a USB stick and answering a few questions, with full-disk or dual-boot options. The site lists x86 and ARM builds (ARM support for NVIDIA DGX Spark and N1X is described as preliminary), a native installer for Apple Silicon Macs (M1–M3 and "Neo"; M4 and newer are described as coming), and a virtual machine option for trying it on Apple Silicon Macs and Windows 10/11. The latest release listed on the site is 4.5.0.

Omarchy includes a theme system that restyles the terminal, bar, notifications and wallpaper together, a choice of editors (Neovim by default) and terminals (Foot by default, plus Alacritty, Ghostty and Kitty), and development environments such as Ruby on Rails, Laravel and Node.js managed through Mise. A community plugin ecosystem adds widgets and system tools. The agent features depend on the user choosing and signing in to a separate agent, which may be a third-party service.
