The accessible, privacy-compliant CAPTCHA alternative

Prevent bots. Ensure privacy.

Based on proof-of-work mechanisms and advanced risk signals, Friendly Captcha employs a fundamentally new approach to securely defend your websites and online services from bots and spam.

Friendly Captcha doesn’t track your users. It is compliant with GDPR, CCPA, and global privacy regulations. Plus, your users no longer have to deal with tedious labeling tasks. They don’t have to do anything at all.

Start with Friendly Captcha

Truly invisible CAPTCHA challenge

Experience Friendly Captcha yourself.

Friendly Captcha is the first truly invisible CAPTCHA based on proof-of-work. Instead of prompting any visible challenge to the end user, it checks the end user’s device in the background.

Friendly Captcha generates a unique crypto puzzle for each user’s device. As soon as the user starts to fill in a protected form, it will be solved automatically. Solving it will usually take a few seconds. By the time the user is ready to submit, the puzzle is probably already solved.
