hCaptcha Free add-on is a drop-in replacement for reCAPTCHA.
Note: we also offer a hCaptcha Premium add-on that includes the payout feature: hCaptcha pays you, the website owner, every time an image challenge is solved by your website’s visitors.
How is hCaptcha different?
hCaptcha is the only major captcha service not owned by an ad network.
hCaptcha's incentive is to maximize accuracy, not ad revenue: bot answers are useless for our customers, who need human training data.
hCaptcha cares about privacy, transparency, and fairness.
Knowing who an individual is has minimal value for hCaptcha. We only care whether they are human or a malicious actor.
hCaptcha shares the value of work done while users prove their humanity.
Instead of offering a service of questionable value while extracting labor with real value, hCaptcha provides both compensation and strong anti-bot protection. - See hCaptcha Premium add-on.
How does hCaptcha compare with reCAPTCHA?
hCaptcha also stops bots and spam, but gives you more control over the difficulty level you need for your site and does a better job of protecting your users' privacy.
hCaptcha has 100% of the features of reCAPTCHA V2 and is API-compatible with reCAPTCHA V2.
