Percy.io, a continuous visual integration tool

In plain words

Percy.io is a continuous visual integration tool that helps teams automatically catch visual changes in web applications. It integrates into development workflows to compare screenshots across browsers and devices, flagging unintended design regressions before they reach production. The platform is designed for developers and QA teams working on web projects who need to maintain visual consistency across their digital products.
