WebMate: Automatic cross-browser testing

Where is the pricing? Is there a demo? Am I supposed to share my details and create an account based on screenshots and hope that I can pay "some price" or live with "some restrictions" after signing up? Also, why would a static site stutter when I scroll?

I get a certificate warning when accessing the site on Android 4.4.2 NET:ERR_CERT_CERTIFICATION_INVALID with both Chrome and Opera. All is fine on Ubuntu.

It's not serving the proper chain certificate: https://whatsmychaincert.com/?app.webmate.io

Yet another site that feels the need to hijack and speed up the scroll.

How do I set-up a paid account?
