Cloudflare site speed: the slowest and fastest sites →Where this comes from
We detect technologies from each site's own pages (code, headers and scripts) when it's enriched, so this covers the sites we've scanned, not the whole web, and it grows every day. Popularity is the Tranco list of the top million sites; only sites in it are named here. Updated October 2026.
