T3 Code for NixOS

Unofficial Nix package for T3 Code - a minimal web GUI for coding agents.

Installation

NixOS (Recommended)

Add the flake input and import the module:

{
  inputs = {
    t3code = {
      url = "github:rodeyseijkens/t3code-nix";
      inputs.nixpkgs.follows = "nixpkgs";
    }
  };

  outputs = { self, nixpkgs, t3code, ... }: {
    nixosConfigurations.myhost = nixpkgs.lib.nixosSystem {
      modules = [
        t3code.nixosModules.default
        # ... your other modules
      ];
    };
  };
}

The module automatically:

• Enables AppImage support (programs.appimage.*)
• Adds t3code to system packages

Home Manager

{
  inputs = {
    t3code = {
      url = "github:rodeyseijkens/t3code-nix";
      inputs.nixpkgs.follows = "nixpkgs";
    }
  };

  outputs = { self, nixpkgs, t3code, ... }: {
    homeConfigurations.myhost = home-manager.lib.homeManagerConfiguration {
      modules = [{
        home.packages = [
          t3code.packages.x86_64-linux.default
        ];
      }];
    };
