FuckCaptcha is an open reference for understanding CAPTCHA types, their context and the approaches documented around them. It is intended for education and authorized research, not for evading protections on services without permission.
Bring a changing landscape of CAPTCHA systems into one approachable, maintained reference. The project aims to make the material easier to navigate, compare and cite while keeping responsible, authorized use explicit.
The project brings together a practical, maintainable reference for researchers, developers and curious readers: identify common CAPTCHA families and their context, compare documented tools and approaches with their trade-offs, and stay responsible by prioritizing authorized research, privacy and transparent sourcing.
