Privacy focused

Doesn't track, doesn't profile your users.

Robust and Accurate

Got users behind NATs? No issues. We don't use IP address for rate-liming. NAT or not you get the mCaptcha experience.

Best-in-class UX

mCaptcha is silent, so silent that your users won't even feel it. No more annoying images, no more helping for Big Brothers with their ML stuff
