Compare two sites

See the difference between your production and staging environment. We will run the comparison and manually mark the changes for you.

Shedule monitoring

Daily, weekly monitoring on your schedule

Monitoring will take screenshots and compare them with screenshots of previous run (i.e. yesterday) so you just receive an email notificaiton if anything found.

Adjust Page Content to avoid False Positives

Take care of ads, carousels, video embeds, popups so they never trigger false positives in your comparisons.

Better results with our Comparison Algorithm

If you’ve done visual regression testing before, you know that the tiniest vertical shifts due to browser rendering can lead to highlighting way bigger area than actually changed.

Our algorithm detects these shifts and provides much better results than pixel perfect comparison algorithms.

Create tickets for developers right from the tool

You can create ticket in your bug-tracking system (i.e. Jira, Asana, Trello, Basecamp etc.) right from Diffy with our Zapier integration
