Diff sensitivity

Learn how to adjust the sensitivity when comparing old and new builds

Not every project is the same and some require more attention to detail than others for each change. This setting allows adjusting the diff sensitivity when differentiating between the base build (Original) and the head build (New) on the project. The setting takes effect on the next build and does not affect past builds.

Select your build, navigate to Project settings, then Advanced Options, and Adjust Diff Sensitivity. Percy allows you to configure the sensitivity between Strict, Recommended, and Relaxed.

  • Strict: Highlight every pixel difference, including image artifacts and font smoothing/antialiasing
  • Recommended: Strike a balance between highlighting important changes and ignoring noise
  • Relaxed: Highlight only the most prominent color shifts

Diff Sensitivity

IMPORTANT
Safari screenshots will always render in “Relaxed” due to its non-deterministic rendering engine.

NOTE
Currently, this setting only affects sensitivity to color differences.
