Pick a tool

  • Image diff tool — Compare two screenshots or images in your browser: a diff overlay, the share of changed pixels and the same changed/unchanged verdict Snapvisor's engine gives.
  • Screenshot calculator — Work out how many screenshots your visual tests take a month and what that costs on Snapvisor, Percy, Chromatic and Applitools, from their published prices.

Visual testing in your pipeline

The visual regression testing guide explains how screenshot comparison works in CI, and the comparison pages set Snapvisor beside Percy, Chromatic and Applitools.

Snapvisor

Visual regression testing that catches every pixel before it ships — built on a proven open-source visual-diff engine.
