KeyCAPTCHA - Innovative Anti-Spam Service.

We Pay for Your Protection

KeyCAPTCHA is an effective monetizing tool of your website. In contrast to other systems, KeyCAPTCHA solidly protects your website against spam as well provides you with an income acquisition instrument. The more popular your website is, the much more income you will get.

Unlike many other captchas, it does not require any text typing.

Variants of Using KeyCAPTCHA:

1. You earn money by using KeyCAPTCHA. In this case we pay you for ads in KeyCAPTCHA on your website. 2. You pay us for personal CAPTCHAs. In this case you can use your own images to create your own CAPTCHAs (containing your or third-party advertisement or without any ads) which will be displayed on your websites. 3. Combination of 1 and 2. 4. Free KeyCAPTCHA. In this case you don't earn money and you don't pay us. If you choose this way, we will display our standard CAPTCHAs (without any ads) on your websites.

KeyCAPTCHA Unique Technologies


 * Instead of guessing symbols, our CAPTCHA offers visitors to complete an easy interactive task.
 * If KeyCAPTCHA hasn't been solved correctly, page refreshing doesn't take place that allows the user not to fill in the form repeatedly. It occurs since there is an initial checkup of CAPTCHAs in the KeyCAPTCHA servers before sending a filled-in form to the protected web server.
 * Our CAPTCHA also can be used even if your hosting provider blocks all outgoing connections.

Effective Anti-Spam Protection
