Discover What Customers are Saying About MTCaptcha

Discover How MTCaptcha is Used Across Enterprises, SMEs, and Non-profit Organizations According to G2 Reviewers

Affordable, effective captcha solution for respecting privacy law requirements

"MTCaptcha provides a great alternative for captcha that adheres to current privacy laws that other captcha solutions do not.  Low-friction invisible captcha is available.  The solution is priced well, and different pricing options are available.  Their documentation and tools were well-designed and thorough, to make it easy for us to put together our solution for our rather complex sites, and to observe the solution at work once deployed.  What impressed us most was that their team was incredibly responsive with high-expertise assistance where needed."

Great product, great service

"MTCaptcha is privacy compliant in the EU, other than many of their competitors.We as a startup received a lot of help from the team. We also got the possibility to check out the enterprise version for a limited time.Implementing MTCaptcha to any site was quite easy and worked well. We are more than satifsfied!"

A superb alternative to all other captcha services

"Ease of use and support.  Great to work with, very responsive.  Listens to customer needs and adapts.So far we haven't had many downsides.  A few minor (and I do mean minor) quirks, but they worked through most of them."
