hCaptcha Reviews

  1. It's super easy, straightforward and shouldn't take you more than 20-40 minutes to integrate

    To summarise the process of migrating from reCaptcha to hCaptha:

    1. 👌 It's super easy, straightforward and shouldn't take you more than 20-40 minutes
    2. 👁 You are feeding less data to Google
    3. 💸 You earn crypto/money (I have no idea what's the potential though)

    Here it is my original review

    🏁 Competitors: reCAPTCHA
    👍 Pros:    Easy integration|Privacy concisous|You earn money

Cloudflare replaced reCAPTCHA with hCaptcha. I followed their example. It took me 18 min.
Cloudflare announced yesterday that they are moving away from Google's reCAPTCHA in favour of hCaptcha. In my opinion, that is huge! Given the amount of traffic transiting through CloudFlare. That has cut some significant level of vision from Google's all-seeing and tracking eye. Moreover, they are giving a good example for others to follow.

Moving from reCAPTCHA to hCaptcha
We evaluated a number of CAPTCHA vendors as well as building a system ourselves. In the end, hCaptcha emerged as the best alternative to reCAPTCHA. We liked a number of things about the hCaptcha solutions: 1) they don't sell personal data; they collect only minimum necessary personal data, they are transparent in describing the info they collect and how they use and/or...

  • Figured out how to make HCaptcha work -- Instructions Inside.
    That's it, and HCaptcha will start working. I would imagine it's a better idea to add a specific site exception for hcaptcha.com, and I'm sure I will later, but just really didn't have the patience to do it via screen reader right now. Source: over 1 year ago

  • New Bungie store password reset broken :(
    First of all, you can stop trolling. It's not about the actual technology, as it may be hcaptcha.com for change or any others like that. It's about not relying on badly aged technology which is only creating problems for users, not for the bots, as this level of noise and numbers/letters is no longer an issue even for javascript-based AI.
