Decisions about Percy

Here are some stack decisions, common use cases and reviews by companies and developers who chose Percy in their tech stack.

Hi Team, I am looking for a tool to best work on visual test automation - Just to capture screenshots each day and compare on the pre-production site.

Currently, I am evaluating Percy, Ghost Inspector, and Applitools (no doubt Applitools is great with its comparison mechanism but cost-wise it's a bit on the higher end at the moment). Could you please let me know which one will be the best tool for visual comparisons?
