CaptchaFox for WordPress


CaptchaFox defends and safeguards your website against automated attacks such as account takeover, spam, scalping, and web scraping, while adhering to EU data protection regulations.

It utilizes a variety of data signals and challenges to verify the authenticity of the user without the use of cookies or trackers.
The challenges have low friction and are easily solvable for humans, but difficult for bots. With the one-click challenge, legitimate users don’t even know they’re being challenged.

This plugin comes with out-of-the-box support for popular form plugins, such as Contact Forms 7, WPForms, Woocommerce, Mailchimp, and more. Therefore, no developer experience is required.

I needed a GDPR-compliant solution and captcha fox fully meets this requirement. The setup was easy and it runs flawlessly. In some quick tests I did, it was effective at detecting automated requests, such as bots.

We needed a privacy-compliant alternative to reCaptcha and CaptchaFox ticked all the boxes. It protects us from spam and bots without any problems. Highly recommended if you are looking to switch.
