GTmetrix — Website Speed and Accessibility Test
GTmetrix
GTmetrix tests how fast a web page loads and returns a Lighthouse-based report with Core Web Vitals, waterfall charts and fix suggestions; you can pick the test location, a simulated device and a connection speed, and schedule recurring tests with email alerts. The home page offers a free start without a credit card, but the pricing page lists only paid PRO plans, and the lowest one includes 50 on-demand tests each month and one monitored slot. The FAQ adds that some options, such as other test locations, need a log-in.
