CDN & Hosting
2,209 of the 1,000,000 top sites in our Tranco top-1M census run GitHub Pages (0.2%). GitHub's free static-site hosting service, often used for docs and project sites. Detection is homepage-level HTML/header fingerprinting, so a site can run GitHub Pages on other pages without it showing here.
