Find subtle differences

When you have to play “spot the difference”, the Chrome extension will help you out and pin-point any changes. It is often helpful to ignore “Positioning”, as small changes will often result in most elements being “shuffled around”.

Try to manually spot the difference between this page and this page. It is very hard to find the differences manually. The Chrome extension on the other hand, will quickly point you to it.

Filter for relevance

Our powerful filters let you find what is relevant for you. Ignore font but not text. Ignore color but not size. Use our included filter or define your own with our powerful git-like syntax.

Test it yourself: compare this budget to this budget and find where the numbers differ…

Work with animations

How do you diff moving animations? Can you even find the difference as a human?

Well … recheck-web can. Try comparing this animation to this animation. And again, ignoring the positioning, recheck-web gives you just what you want, and even tells you that the animation starts 0.3 seconds later…

Better than pixel-diffing

Compare that to the current state-of-the-art in cross-browser and visual regression testing, which is (AI-enhanced) pixel-diffing:

  • Pixel-diffing is indeterministic.
  • Pixel-diffing gives both false positives (irrelevant changes) and false negatives (misses relevant changes).
  • You can’t influence the (ai-based) filtering.
  • Pixel-diffing just gives you a marked image, leaving the analysis up to you.

The recheck-web Chrome extension relies on the free version of rehub. If you want to use it regularly, we suggest upgrading your rehub plan to Standard.
