Omarchy Nix

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 isn't meant to be full feature parity with Omarchy and likely never will be, especially with how fast the feature development and funding has been for that project. Instead, think of this as more of a launch pad to get your own similar Nix config set up!

I've personally moved to using regular Arch Omarchy full-time for a number of reasons. I'm not actively working on this repo but if you'd like to contribute please send a PR :)

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 = "[email protected]";
            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 themes from wallpaper images using:

• generated_light - generates a light color scheme from wallpaper
• generated_dark - generates a dark color scheme from wallpaper

Generated themes require a wallpaper path to be specified:

{
  omarchy = {
    theme = "generated_dark"; # or "generated_light"
    theme_overrides = {
      wallpaper_path = ./path/to/your/wallpaper.png;
    };
  };
}

Wallpaper Overrides

Any theme can be customized with a custom wallpaper by specifying wallpaper_path in theme_overrides. For predefined themes, this will only change the wallpaper but keep the original color scheme:

{
  omarchy = {
    theme = "tokyo-night"; # or any other predefined theme
    theme_overrides = {
      wallpaper_path = ./path/to/your/wallpaper.png;
    };
  };
}

Generated themes automatically extract colors from the wallpaper and create a matching color scheme for all Omarchy applications (terminal, editor, launcher, etc.).
