Build Tools & Dev Infrastructure
1,957 of the 1,000,000 top sites in our Tranco top-1M census run Rollup (0.2%). A JavaScript module bundler that compiles small code pieces into a single optimized bundle, popular for building libraries. Detection is homepage-level HTML/header fingerprinting, so a site can run Rollup on other pages without it showing here.
