hax

hax is a minimalist, terminal-native coding agent designed for developers who prioritize efficiency and transparency. Key features include: * Instant startup and low memory footprint * First-class support for local models * Preserves native terminal scrollback * Inspectable model-facing conversation transcripts * Broad provider compatibility (OpenAI, Anthropic, OpenRouter, llama.cpp, and more) This tool is built as a single native C binary, ensuring it starts instantly and consumes only a few megabytes of memory. This lightweight design leaves more system resources available for running local code models. hax seamlessly auto-discovers configuration from running `llama-server` instances, making it easy to integrate your preferred local environments without complex setup. hax respects your terminal environment by streaming Markdown and live tool output, reflowing content for optimal display without taking over the terminal. It only redraws the current streaming line or input area, preserving your native scrollback. Developers can inspect exact model-facing conversations through a usable transcript view and even collect detailed wire protocol traces, ensuring full transparency into its operations. Designed as a well-behaved Unix tool, hax uses XDG paths, provides clean plain-text input/output, and supports composition via subprocesses rather than relying on a plugin architecture. It's ideal for developers who live in the terminal, run local models, audit tool behavior, or work in resource-constrained environments.
