JavaScript Library & Framework
69,620 of the 1,000,000 top sites in our Tranco top-1M census run Fancybox (7%). A JavaScript lightbox library that displays images, videos, and other content in a modal overlay. Detection is homepage-level HTML/header fingerprinting, so a site can run Fancybox on other pages without it showing here.
