CDN & Hosting
70,653 of the 1,000,000 top sites in our Tranco top-1M census run jsDelivr (7.1%). A free public CDN that serves files from npm, GitHub, and other open-source package registries. Detection is homepage-level HTML/header fingerprinting, so a site can run jsDelivr on other pages without it showing here.
