Protect your applications from bots and bad actors without compromising user privacy or security.
Prosopo is the only fully decentralised bot protection service for applications. We provide a simple, secure and scalable solution to protect your users from bots and bad actors without compromising user privacy or security.
Prosopo Captcha is a drop in replacement for reCaptcha and hCaptcha, allowing you to be up and running in minutes.
We don't store any data. Bot detectors receive minimal information from your application and there is no centralised user data store.
Grow your site from 0 to 100,000 users without paying a penny. We'll never charge for our image based CAPTCHA service.
