Omarchy-nix (Omanix?) is an opinionated NixOS flake to help you get started as fast as possible with NixOS and Hyprland. It is primarily a reimplementation of DHH's Omarchy project - an opinionated Arch/Hyprland setup for modern web development.

This was mostly spun up in a weekend so if you have any issues please let me know, my goal is to eventually make this as seamless an install experience as Omarchy itself!

Quick Start

To get started you'll first need to set up a fresh NixOS install. Just download and create a bootable USB and you should be good to go.

Once ready, add this flake to your system configuration, you'll also need home-manager as well: (You can find my personal nix setup here too if you need a reference.)

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-25.05";
    omarchy-nix = {
        url = "github:henrysipp/omarchy-nix";
        inputs.nixpkgs.follows = "nixpkgs";
        inputs.home-manager.follows = "home-manager";
    };
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { nixpkgs, omarchy-nix, home-manager, ... }: {
    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
      modules = [
        omarchy-nix.nixosModules.default
        home-manager.nixosModules.home-manager #Add this import
        {
          # Configure omarchy
          omarchy = {
            full_name = "Your Name";
            email_address = "your.email@example.com";
            theme = "tokyo-night";
          };
          
          home-manager = {
            users.your-username = {
              imports = [ omarchy-nix.homeManagerModules.default ]; # And this one
            };
          };
        }
      ];
    };
  };
}

Configuration Options

I've specified some basic configuration options to help you get started with initial setup, as well as some simple overrides for common configuration settings I found I was modifying often. These are likely subject to change with future versions as I iron things out.

Refer to the root configuration file for more information on what options are available.

Themes

Omarchy-nix includes several predefined themes:

tokyo-night (default)
kanagawa
everforest
catppuccin
nord
gruvbox
gruvbox-light

You can also generate a custom theme from any wallpaper image:

{
  omarchy = {
    theme = "custom";
    customTheme = {
      wallpaperPath = ./path/to/your/wallpaper.png;
      variant = "dark"; # or "light" for light themes
    };
  };
}

This will automatically extract colors from your wallpaper and generate a matching color scheme for all Omarchy applications (terminal, editor, launcher, etc.).
