From the README
<div align="center"> # hwatu **Headless UI verification for coding agents** <a href="https://github.com/hongnoul/hwatu/releases/download/readme-assets/demo-aiuc.mp4"></a> </div> hwatu is a headless verification harness for coding agents: a warm WebKit daemon driven over CLI, MCP, or one JSON line per Unix-socket connection. Instead of "looks right to me", the agent gets **one-call verified page checks in ~35 ms**, **pixel-diff scores it can climb**, **animations as numbers**, and **headless windows that never steal focus**, at any parallelism. Jcode drives it natively as its `browser` backend. When a check needs a human (a CAPTCHA, a judgment call), `hwatu focus <id>` materializes the same live session as a real window. ## Documents - [Agent guide](docs/agents.md): protocol, primitives, verification loops - [Benchmarks](docs/benchmarks.md): every number, measured, with methodology - [Vision](VISION.md): durable product principles, native platform strategy - [Human guide](docs/huRead full README on GitHub →
