CAPTCHA & Bot Protection
50,387 of the 1,000,000 top sites in our Tranco top-1M census run Cloudflare Turnstile (5%). Cloudflare's non-interactive CAPTCHA replacement, bundled free with its CDN/WAF. Detection is homepage-level HTML/header fingerprinting, so a site can run Cloudflare Turnstile on other pages without it showing here.
