CaptchaFox is a German GDPR-compliant bot protection service from Scoria Labs GmbH that stops spam, fake signups, and fraud without the usability and privacy baggage of Google reCAPTCHA.

Friendly Captcha is a privacy-first bot protection service from Germany that replaces image-labelling CAPTCHAs with silent proof-of-work challenges solved in the background by the user's browser.
