About Website Speed Checker
Free online Website Speed Checker tool.
Website Speed Checker measures how quickly a page becomes usable and pinpoints what is holding it back. Paste a web address and the tool runs a simulated load, reporting time to first byte, first contentful paint, largest contentful paint, cumulative layout shift and total page weight, then grades the result from slow to fast. Each critical metric comes with a plain English fix, such as compressing images, cutting redirects or deferring scripts, so you know exactly where to start. Marketers and developers run Website Speed Checker before every launch and after every deploy because faster pages rank better in search and keep visitors from bouncing. The check is free, needs no account and executes entirely inside your browser without sending the tested page anywhere.
