Why Use This Flake?

While there are existing Claude Code packages in the Nix ecosystem ([llm-agents.nix](https://github.com/numtide/llm-agents.nix) and [nixpkgs](https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/by-name/cl/claude-code/package.nix)), this flake provides the **official pre-built binary distribution** with several advantages:

Performance Benefits

Superior Bun performance: Pre-built binaries compiled with Bun offer better performance than Node.js-based distributions with faster startup times, lower memory usage, and improved execution speed

Official Support

Recommended by Anthropic: The official Claude Code documentation recommends using the pre-built binary distribution for optimal performance
Direct from official distribution: Binaries downloaded directly from Anthropic's servers
Guaranteed compatibility: Official builds are tested and verified by Anthropic

Additional Benefits

Faster updates: Automated hourly checks ensure you get the latest version quickly
Consistent behaviour: Same binaries used across all platforms match official installation methods
