Solo for Nix

A Nix flake for Solo on x86_64 Linux. It packages the same Linux release that soloterm.com offers for download and follows it automatically.

Install

Try it without installing:

nix run github:soloterm/nix

Install it into your profile:

nix profile install github:soloterm/nix

Or add it to a NixOS or Home Manager configuration:

{
  inputs.solo.url = "github:soloterm/nix";

  outputs = { nixpkgs, solo, ... }: {
    nixosConfigurations.my-machine = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        {
          environment.systemPackages = [ solo.packages.x86_64-linux.default ];
        }
      ];
    };
  };
}

Solo is commercial software, so its license is marked unfree. The flake's own package is already allowed. If you use overlays.default with your own nixpkgs instead, allow it there:

nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [ "solo" ];

The package installs three programs: Solo (the app), solo (the command line tool), and mcp (the helper that coding agents use to talk to Solo).

Updates

Nix manages updates for this package, so Solo's built-in updater stays off. Run nix flake update solo in your configuration, or nix profile upgrade --all for a profile install.

This repository checks soloterm.com every hour. When a new release is published to everyone, it verifies the release's signature, builds the package, launches Solo on NixOS, and only then updates source.json.

How it is built

The package extracts the Linux AppImage and relinks Solo's own binaries against nixpkgs' WebKitGTK and GTK, instead of running the libraries the AppImage bundles. Solo runs natively, not in a sandbox, so tools like sudo work normally in its terminals.

On NixOS, graphics come from the system's drivers (hardware.graphics.enable). With Nix on another Linux distribution, the app may need a wrapper such as nixGL to find your GPU drivers.
