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

Ships as a single native C binary using only a few MB of memory (leaving RAM for local LLMs), installable via Homebrew on Linux and macOS. Supports OpenAI, Anthropic, Codex (via ChatGPT subscription), OpenRouter, and local llama.cpp models with auto-detected provider capabilities; deliberately skips MCP marketplaces and plugin runtimes.
