JavaScript Library & Framework
40,938 of the 965,200 top sites in our Tranco top-1M census run React (4.2%). Meta's component-based UI library, the most widely used modern JS framework. Detection is homepage-level HTML/header fingerprinting, so a site can run React on other pages without it showing here.
