Hax – a minimalist, terminal-native coding agent written in C

Hax is a lightweight, terminal-native coding agent written in C that prioritizes minimalism and local model support, featuring instant startup, minimal memory usage, and compatibility with multiple LLM providers including OpenAI, Anthropic, and llama.cpp. The tool is designed for developers who work in terminals, run local models, and want transparent visibility into agent operations, with a philosophy that deliberately omits features like plugin systems and IDE panels in favor of Unix-style simplicity. Installation is available via Homebrew or prebuilt binaries for Linux and macOS, with interactive and command-line modes for code assistance tasks.
