reCAPTCHA helps prevent automated abuse of your site (such as comment spam or bogus registrations) by using a CAPTCHA to
ensure that only humans perform certain actions.
-
It's Free! Yep, reCAPTCHA is free. The only reason we might charge is if you require special services from us.
-
It's Useful. Why waste the effort of your users? By using reCAPTCHA instead of other
CAPTCHA implementations, you are helping to digitize books.
-
It's Easy. reCAPTCHA is a Web service. As such, adopting it is as simple as adding 4 lines of code
on your site. For many applications and programming languages such as Wordpress
and PHP we also have easy-to-install plugins available.
We generate and check the distorted images, so you don't need to run costly image generation programs.
-
It's Accessible. Most other implementations of CAPTCHAs block visually impaired individuals,
who cannot read images of distorted text. reCAPTCHA, on the other hand, has an audio test that allows blind people to
freely navigate your site.
-
It's Secure. reCAPTCHA is run by the original creators of CAPTCHA and has the
highest security standards. Many other implementations of CAPTCHAs can be easily broken.
