Nix flake packaging for [free-claude-code](https://github.com/Alishahryar1/free-claude-code) by [Ali Khokhar (Alishahryar1)](https://github.com/Alishahryar1) - a local Anthropic-compatible FastAPI proxy that fronts Claude Code (and other coding agents) with any OpenAI-compatible model backend.

What Is This?

A Nix flake that builds free-claude-code from a pinned upstream commit, plus a Home Manager module that runs `fcc-server` as a user service and ships an `fcc` launcher wired to it.

• Package - fcc-server, fcc-claude, fcc-cline, fcc-codex, fcc-desktop, fcc-hermes, fcc-opencode, fcc-pi entry points from a hatchling wheel on Python 3.14
• Home Manager module - services.free-claude-code: a loopback-bound fcc-server user service plus the fcc launcher pointing Claude Code at it
• Update automation - daily upstream commit detection, hash recomputation, and a verified build

Installation

Add as a flake input:

{
  inputs.free-claude-code = {
    url = "github:Daaboulex/free-claude-code-nix";
    inputs.nixpkgs.follows = "nixpkgs";
  };
}

Then add the overlay:

nixpkgs.overlays = [ inputs.free-claude-code.overlays.default ];
