Diff Sensitivity

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.

Percy provides five values ranging from Strict to 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


Safari screenshots will always render in "Relaxed" due to its non-deterministic rendering engine


At the moment, this setting only affects sensitivity to color differences
