PerfDebugger is a Chrome extension designed specifically for frontend developers to monitor and debug performance issues in real-time. It provides immediate insights into Core Web Vitals such as LCP, FCP, CLS, INP, and TTFB without the delays associated with traditional tools like Lighthouse. This tool also features live memory monitoring, including JavaScript heap tracking and leak detection, making it an essential resource for developers focused on enhancing user experience.

Unlike conventional performance auditing tools, PerfDebugger operates directly within your browser, offering instant results and real device metrics. It automatically flags slow resource requests and is compatible with any website, ensuring versatility across different projects. With a strong emphasis on privacy, all data is stored locally, requiring no external tracking or accounts. This makes PerfDebugger a reliable choice for developers looking for efficient and secure performance monitoring.
