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 on Percy platform 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 relevant changes
Highlight only the most important changes on a page using a proprietary method.
Increase in productivity
The time required to review changes drastically reduced for a faster visual testing experience
Reduced noise and flakiness
App 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, thereby eliminating the false positives due to anti-aliasing.
Intelligent text stabilization
Minor character shifts during rendering leading to false positives are a thing of the past. Percy Visual Engine stabilizes text shifts using an OCR (Optical Character Recognition) library.
Ignore regions
You can now ignore specific regions on a page, so you no longer have to worry about dynamic data causing flakiness.
