Web Framework
3,023 of the 1,000,000 top sites in our Tranco top-1M census run Astro (0.3%). A JavaScript web framework focused on content-driven sites that ships minimal client-side JavaScript by default. Detection is homepage-level HTML/header fingerprinting, so a site can run Astro on other pages without it showing here.
