Main Features / Use Cases

Custom Image Compare Algorithm

We have build a custom algorithm that understands vertical shifts so you get less false positives.


We use highly scalable infrastructure of workers so it is not a problem to take thousands of screenshots from your site.

Predefined and Custom Environments

So it is easy to compare your Live with Staging. If you are using temprorarly build environments -- you can compare them as well.


All actions available in UI are exposed with REST API too. So you can do really deep integrations to you CI system. We also have swagger UI for you to try API's out.

Mask / Exclude elements

In order to avoid false positives we can remove / mask DOM elements on the page prior taking the screenshot. Good for hiding ads, slides, popups.

Delay, scroll, javascript

Execute custom javascript, set a delay or scroll the page to get all your assets in place for the screenshot.

As authenticated user

You can take screenshots as authenticated user to test your backend. Support Drupal, Wordpress and any custom form to login.

Teams, notifications

  • Easier to share results with clients
  • No need for a server, a year of service probably less than the effort of setting up a visual testing server
  • On top you get some nice extras like Slack integration with no effort
