Hax Is a Coding Agent Written in C That Deliberately Has No MCP Marketplace, No Plugins, and No Permission Prompts
Hax hit HN on August 12 (104 points) as a single native C binary, MIT licensed, that starts instantly on a few megabytes of memory and auto-discovers model and runtime capabilities instead of requiring per-provider config. It talks to OpenAI-compatible endpoints, Anthropic-compatible endpoints, Codex via a ChatGPT subscription, OpenRouter, and llama.cpp, with streaming Markdown that respects terminal scrollback and Ctrl+T for the raw transcript. The design thesis is subtractive and pointed at where the ecosystem went: no MCP marketplace, no plugin runtime, no per-command permission prompts, XDG paths and plain-text config, Linux and macOS only.
