JavaScript Library & Framework
47,495 of the 1,000,000 top sites in our Tranco top-1M census run React (4.7%). 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.
