Automates Chrome via Puppeteer scripts that all output JSON, making it easy to pipe results through jq or chain commands. You get the standard automation toolkit (navigate, click, fill forms, screenshot) plus debugging helpers like console monitoring, network traffic analysis, and Core Web Vitals measurement. Screenshots auto-compress with ImageMagick if they exceed 5MB, which matters if you're feeding them to Claude or Gemini. The snapshot script is clever for discovering selectors on unfamiliar pages. Requires some setup on Linux for system dependencies, but the install script handles OS detection. Most useful when you need structured output from browser automation rather than writing throwaway Puppeteer code yourself.
