What we make
A CAPTCHA for websites and apps: a box that most people tick once, a quick puzzle only for visitors who look automated, and a verify API your server calls before accepting a form.
FitMyKB Verify
About FitMyKB Verify
A CAPTCHA that asks real people for one tick, makes bots pay for every try, and keeps no profile of anyone.
How it works
Each visitor's browser does a small piece of proof-of-work, cheap for one person and expensive for anyone sending thousands of requests. Light signals add a score from 0 to 1. The puzzles, slide, rotate, tap, picture grid and mixed, are drawn fresh by our server.
Private by design
No cookies, no cross-site tracking and no advertising profile. We don't see your forms' content, and visitors' IP addresses are used scrambled, for minutes, only to slow down repeated failures.
Compatible
The widget accepts hCaptcha and reCAPTCHA markup and answers siteverify in the same shape, so switching takes minutes.
Who we are
FitMyKB Verify is built and run in India by the FitMyKB team, with servers in India.
