This is a comparison of online services which helps to prevent automated abuse of your site (such as automatic comment spam or registrations) by using a CAPTCHA to ensure that only humans perform certain actions.

While these services helps to reduce spam, they will not totally prevent it, since some humans add manually their comments.

These services usually shows a text in an image and visitors must type it to validate the form. To ensure accessibility, some services provide an audio CAPTCHA so that the visitors can listen to it, if they are unable to see the image.

A dedicated comparison has been created for services with advertisements solutions combined:
