Friendly Captcha for WordPress


Friendly Captcha is a privacy-first anti-bot solution that protects WordPress website forms from spam and abuse.

Do you use a captcha like reCAPTCHA to keep out bots? Friendly Captcha is a powerful anti-spam service that blocks spam-bots without annoying captcha images and protects user privacy.

How Friendly Captcha Works

Friendly Captcha is a tool for preventing spam on your website. Other CAPTCHAs are a burden on your users, Friendly Captcha respects your users.

Friendly Captcha is a proof-of-work based anti-bot solution in which the user’s device does all the work. We generate a unique crypto puzzle for each visitor.

Solving it will usually take only a few seconds. As soon as the user starts filling the form it starts getting solved. By the time the user is ready to submit, the puzzle is probably already solved.

Friendly Captcha prevents spam and doesn’t punish real users in doing so.

However, you may wish to email the authors of plugins you’d like to support Friendly Captcha: it will usually take them only an hour or two to add native support if they choose to do so. This will simplify your use of Friendly Captcha, and is the best solution in the long run.


  1. Upload friendly-captcha folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Enter your Site Key and API Key in the Settings -> Friendly Captcha menu in WordPress
  4. Enable the desired integrations


How to use the Friendly Captcha plugin?

The Friendly Captcha plugin supports WordPress core and many plugins with forms automatically.

To use Friendly Captcha, you can create an account at and create a Site Key and API Key there. It is best to copy both keys and save them in a safe place. Then go to the Friendly Captcha plugin settings page and enter the created site key and API key. Below that, select the forms you want to protect. Finally, save these settings by clicking on the “Save Changes” button at the end of the settings page.

You don’t support a certain plugin. How can I get support for it added?

Open a PR on GitHub here or just email the authors of the plugin itself. Adding Friendly Captcha support is typically quite a quick task for most plugins.

On first sight this CAPTCHA solution is what many people are looking for: Easy to implement and fully GDPR-compliant. With the “Personal” plan there is a free plan available however I got an email from the friendly captcha team to upgrade my account. The smallest pricing option is 9 € a month. Sorry guys… for providing a simple piece of software 1.080 € over 10 years is ridiculous and I am out.

I am thrilled! I’ve been looking for a European alternative to ReCaptcha for a long time and Friendly Captcha is simple, accessible and GDPR compliant. After installing the plugin I created an account at Friendly Captcha, created a sitekey and API key there and inserted it into the plugin. Then I selected my used form plugin via checkbox and it worked on the first try. Thanks!

Kein Hinweis darauf, dass das PlugIn kostenpflichtig ist und eine Api benötigt. Egal, ob das PlugIn gut oder schlecht ist, so etwas geht gar nicht!
