How these numbers are calculated

TechLeads scans public websites and detects Cloudflare from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Cloudflare's website count divided by the website counts of all CDN technologies we track; a site using two CDN tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
