WhatRuns has been incredibly useful for me over the years in understanding various site functionalities. As of December 2024, I tested it on multiple sites, and while it generally worked well, it occasionally had issues. Still, for a free tool, it's fantastic.

Whatruns has been hugely useful for me over the years in understanding bits of functionality that sites have. As of December 2024, I've tested it on a bunch of sites and it worked fine although it sometimes doesn't. For a free tool, it's awesome.
