GTmetrix
Test your website speed and find out how to optimize it.
GTmetrix is a web performance testing and monitoring tool that analyzes pages using Lighthouse and generates actionable performance scores and recommendations. It tracks Core Web Vitals, historical performance trends, and real user metrics via CrUX data. Users can monitor pages on a schedule, set up alerts for slowdowns, and test from 26 global locations across 55+ simulated devices.
GTmetrix runs Lighthouse-based analysis on a given URL, produces a scored report with bottleneck details, and can monitor pages on a recurring schedule with alerts.
