    Comments about Friendly Captcha as an Alternative to Cloudflare Turnstile
     
    Guest

    In contrast to Cloudflare Turnstile, Friendly Captcha offers universal browser support and doesn't block users with older browser or devices. Cloudflare still requires user interaction with the Captcha whenever a user seems to be suspicious. That's not invisible at all, and an accessibility challenge.
