JavaScript Library & Framework
766 of the 1,000,000 top sites in our Tranco top-1M census run FlagCDN (0.1%). A CDN serving country-flag icon images, commonly used in language/locale selectors. Detection is homepage-level HTML/header fingerprinting, so a site can run FlagCDN on other pages without it showing here.
