GDPR reCaptcha alternative

Is there any alternativ to reCaptcha?

There are other extensions like joomla-extensions.kubik-rubik.de/ecc-easycalccheck-plus but they don't seem to work together.

Usually, any recaptcha plugin which works with Joomla should work for Events Booking (Individual / and Shopping cart)

For group registration, I am unsure because we have some steps in group registration and have to use AJAX for handle it. If the recaptcha plugin use some kind of javascript code, I guess it won't work with group registration

So for now, recaptcha is still the most reliable captcha option
