JavaScript Library & Framework
16,013 of the 1,000,000 top sites in our Tranco top-1M census run Popper.js (1.6%). A JavaScript library for positioning tooltips, popovers, and dropdown menus relative to an anchor element. Detection is homepage-level HTML/header fingerprinting, so a site can run Popper.js on other pages without it showing here.
