Visual Diffs — Track UX changes with visual diffs on every deploy.

@markzeman writes a post on the update here: https://dev.speedcurve.com/blog/...

Mark from SpeedCurve here. We just added visual diffs which let you track pixel level UX changes on every deploy. It makes the practice of continuous deployment safer by allowing you to quickly focus in on changes in the user experience that you may or may not have expected. Google have been championing this technique and in addition we provide filmstrip and video comparisons powered by the much loved WebPageTest.
