Visual Regression Tool to take website Screenshots and compare the generated images and identify differences pixel by pixel
AUTOMATED VISUAL REGRESSION TOOL for Websites and UI Designs.
The Visual Regression test will fail if the differences between the two pages are higher than a set threshold (“tolerance” can be set from 0% to 90%).
See Screenshots Side-by-Side - Take Website Screenshots and compare the generated images and identify differences pixel by pixel
A comparison image will be shown next to the result’s screenshot that highlights the differences in red.
For example: www.example-staging.com vs. www.example.com
This will run a pixel-by-pixel comparison on each page screenshot and will highlight to look for differences

I did not get any confirmation email, I thought my account was not active as I did not get any email from them. When I found the name from the credit card charge I tried to login but their password reset did not work. They said they could not give me a refund for my 12 months payment, because of the third party service they use. I would not trust Loadfocus testing any important web sites.
Super easy to use. Generates screenshots of staging and production web pages and compares pixel by pixel. Also, generates diff comparison, with a percentage threshold to ignore some of the different pixels found between the two screenshots. Emulates also on different viewport breakpoints (useful for responsive websites) and mobile devices.
Useful extension.
