Spot The Difference Instantly

When you make an update to your website or deploy new code, you want to be in control of your changes. By running the change detection, you will see precisely what has been modified between versions – for desktop and mobile.

With the auto change detection you can check any website for changes in intervals, from hourly up to every 24 hours. You receive a notification when a difference has been found. Use this to keep track of clients as well as competitors websites.
