FuckCaptcha is an open, searchable field guide to 39 CAPTCHA systems, intended to help researchers, developers, and other readers identify challenge types and understand how they differ. Its catalog spans familiar systems such as reCAPTCHA, hCaptcha, and Cloudflare Turnstile, as well as services from Arkose Labs, GeeTest, DataDome, Akamai, and others. It also covers challenge formats including text, audio, sliders, and puzzles. Individual guides provide identification signals, context, references, and documented ways to approach or solve challenges.
The guide also compares free and open-source tools with paid solving services, with a separate index for those options and a collection of further research resources. Five editorial difficulty levels, from low to very high, help readers navigate the catalog, but are explicitly not guarantees of how a CAPTCHA will behave in a given setting. The project’s central aim is to make a changing landscape easier to browse, compare, and cite. It frames the material as educational and for authorized research, emphasizing permission, privacy, applicable law, and service terms rather than unauthorized evasion. Its interactive web version and invitation for contributions are intended to keep the reference accessible and maintained.
