JavaScript Library & Framework
1,063 of the 1,000,000 top sites in our Tranco top-1M census run Polyfill.io (0.1%). A JavaScript polyfill service that served browser-compatibility shims to older or unsupported browsers from a CDN. Detection is homepage-level HTML/header fingerprinting, so a site can run Polyfill.io on other pages without it showing here.
