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
  • Discovering OpenZeppelin Defender features with an NFT Game
    Finally, we build a front end with a captcha feature with NextJS and hCaptcha. - Source: dev.to / about 2 years ago
  • I can't log into Bitwarden.....
    I have Ublock and UMatrix running. Had to whitelist hcaptcha.com and bitwarden.com to get the challenge to pop up. Source: about 2 years 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.

  • Ok, I've migrated email to selfhosted
    Spamassassin or rspamd or ASSP. All very good. Spamassassin just works, but you need to feed it a good cohort of spam and ham (about 1000 messages each). Most people only send it the spam which will then bias it quite a bit and not have it classify spam as spam unless it's the worst of the bunch. Spamassassin is a filter for your mail server. Rspamd is the same idea. ASSP is highly configurable and a proxy. Source: 12 months ago
  • SpamMail
    Https://rspamd.com/ is what we use on our mail servers blocks around 60% of incoming emails some get thu but not a lot. Source: about 1 year ago
  • Tell HN: Gmail's spam filters have gone bonkers
    Definitely. I think Gmail spam filtering has just gone haywire with way too much input, ChatGPT style sales pitches, and too much clutter. At Skiff (https://skiff.com/mail), we use RSPAMD (https://rspamd.com/), an open-source spam filtering framework. It's not as sophisticated, but it is highly explainable and works consistently. I much prefer this + inbox rules to anything else. - Source: Hacker News / over 1 year ago
  • DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD
    When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / almost 3 years ago
  • Rspamd monitoring with OpenBSD relayd
    Well, Rspamd includes web interface to monitor its performance. I combined it with relayd. - Source: dev.to / almost 3 years ago
