JavaScript Library & Framework
5,664 of the 1,000,000 top sites in our Tranco top-1M census run Emotion (0.6%). A CSS-in-JS library that lets developers write component-scoped styles directly in JavaScript. Detection is homepage-level HTML/header fingerprinting, so a site can run Emotion on other pages without it showing here.
