Judge 页面性能体检 is a Chrome add-on designed to diagnose website performance issues effectively. With its intuitive interface, users can quickly identify whether slow page loads are due to backend processing, network congestion, frontend queuing, or personal network issues. This tool is particularly beneficial for non-technical team members, enabling them to submit actionable reports instead of vague complaints about system slowness. The add-on provides insights into the slowest API calls, categorizes performance issues into five distinct labels, and evaluates network conditions with a scoring system.

Key features include the ability to capture HTTP exceptions and monitor JavaScript runtime errors, which can help pinpoint the causes of unresponsive pages. Users can also track their recent actions for easier troubleshooting and generate detailed PDF reports with IP watermarks for accountability. This tool is suitable for various roles within a company, including operations, product management, and customer service, ensuring that everyone can contribute to optimizing web performance.
