JavaScript Library & Framework
519 of the 1,000,000 top sites in our Tranco top-1M census run Preact (0.1%). A lightweight JavaScript UI library with a React-compatible API, aimed at smaller bundle sizes and faster loads. Detection is homepage-level HTML/header fingerprinting, so a site can run Preact on other pages without it showing here.
