Visual testing powered by computer vision
A generational leap in image comparisons—reducing noise and highlighting the most important changes.
Introducing Percy Visual Engine
Percy Visual Engine is the core algorithm that runs all the image comparisons. It is an upgrade of the existing diffing algorithm to bring significant improvement in noise reduction and highlight changes that matter to help you ship with confidence.
The most advanced visual testing algorithm
All new visual testing experience that focuses on changes your users care about.
Noise reduction
Significant reduction of layout shifts and non-deterministic rendering noises.
Highlight the most important changes
Percy now highlights only the most important changes on a page using a proprietary method.
Increase in productivity
Visual testing on Percy is faster now that the time required to review changes has been drastically reduced.
