Introducing Percy Visual Engine
It's an upgrade of the existing diffing algorithm to bring significant improvement in noise reduction & highlight changes that matter to help you ship with confidence.

The most advanced visual testing algorithm
A visual testing experience that focuses on changes your users care about.
Noise reduction
Significant reduction of layout shifts and non-deterministic rendering noises.
Highlight critical changes
App Percy highlights only the most important changes on a page using a proprietary method.
Increase in productivity
App Percy has become faster due to drastic reduction in visual review time.
Reduced noise and flakiness
Percy helps you focus on changes that matter by highlighting only the changes that are most critical to your users.
Page shift detection
App Percy highlights the exact pixels that cause the page shift instead of marking the entire page contents as diff.
Handling anti aliasing noise
Percy Visual Engine uses computer vision to deterministically render each pixel, eliminating the false positives due to anti-aliasing.
Ignore regions
You can now ignore specific regions on a page, so you no longer have to worry about dynamic data causing flakiness.
