From December 16th, 2017 to February 27th, 2018, 100% user give 5-star rating. for LoadFocus: Visual Regression Testing chrome extension.
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.
