JavaScript Library & Framework
32,802 of the 1,000,000 top sites in our Tranco top-1M census run jQuery UI (3.3%). A JavaScript library built on jQuery that provides interactive UI widgets, effects, and utilities. Detection is homepage-level HTML/header fingerprinting, so a site can run jQuery UI on other pages without it showing here.
