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
Our PoW-based solution defends fiersly. mCaptcha makes attacking your site more experience than what it will take for you to respond to the attacker's requests
Client libraries are licensed using properiatary-friendly free software licenses but the core is AGPL'd. We believe this is a tech that can change the way the web works so mCaptcha will always be free
