JavaScript Library & Framework
4,323 of the 1,000,000 top sites in our Tranco top-1M census run styled-components (0.4%). A CSS-in-JS library that lets React developers write component-scoped styles inside JavaScript files. Detection is homepage-level HTML/header fingerprinting, so a site can run styled-components on other pages without it showing here.
