basically what the title says

the ones i’m aware of:

  • google’s recaptcha
  • cloudflare’s hcaptcha

cloudflare being better for privacy compared to google, but still not great afaik

    Cloudflare’s Turnstile has an invisible mode that you’re probably using in a lot of places and aren’t aware of it. It provides an invisible challenge to the browser and requires no interaction. I would say no input require in quite user-friendly.

      I would argue that’s not a CAPTCHA at all, since it’s not a Turing test, but rather a browser inspection.

      In any case, Cloudflare services like these are not remotely privacy-friendly.

      Yes, the Honeypot system, an invisible part, only visible for bots, they use it and get blocked. easy.
