Friendly Captcha is a privacy-first, invisible CAPTCHA alternative that protects websites and apps from bots and spam using proof-of-work, designed for developers and organizations seeking GDPR-compliant bot defense.

---

🚀 Overview

Friendly Captcha is a bot protection solution that replaces traditional CAPTCHAs with a privacy-compliant, invisible mechanism based on proof-of-work and advanced risk signals. It solves the problem of bot-driven spam and abuse on websites and apps while ensuring user privacy by not tracking or requiring users to complete labeling tasks. It's built for developers, businesses, and organizations needing scalable, accessible anti-spam protection without compromising user experience or regulatory compliance like GDPR and CCPA.

Developed by Friendly Captcha GmbH, a German company with a global team and data protection focus, it was created to provide a humane alternative to annoying, tracking-heavy CAPTCHAs. The service processes millions of requests daily across worldwide data centers.

This project addresses user frustration and accessibility issues with legacy CAPTCHAs, targeting web/app developers who prioritize privacy and seamless UX.
