Doesn't track, doesn't profile your users.
Got users behind NATs? No issues. We don't use IP address for rate-liming. NAT or not you get the mCaptcha experience.
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
Already using a captcha solution? No worries, our APIs are compatible with reCaptcha and hCaptcha!
