Build Tools & Dev Infrastructure
9,577 of the 1,000,000 top sites in our Tranco top-1M census run Webpack (1%). A JavaScript module bundler that compiles scripts, styles, and assets into optimized bundles for the browser. Detection is homepage-level HTML/header fingerprinting, so a site can run Webpack on other pages without it showing here.
