CAPTCHA & Bot Protection
30,403 of the 1,000,000 top sites in our Tranco top-1M census run hCaptcha (3%). A privacy-oriented reCAPTCHA alternative, common on sites that opted out of Google's widget. Detection is homepage-level HTML/header fingerprinting, so a site can run hCaptcha on other pages without it showing here.
