Percy
Visual testing as a service
Percy is a visual testing service that automates the detection of visual changes in web and native applications, as well as component libraries, on every code change. It solves the problem of time-consuming and error-prone manual visual checks by providing automated insight into UI differences, helping teams catch visual bugs before they reach customers.
The service offers a visual diff engine powered by computer vision to highlight relevant changes, responsive testing across multiple breakpoints, and snapshot stabilization to minimize false positives. It includes a review workflow with side-by-side comparisons, automatic diff matching, commit synchronization, and status updates in pull requests. Percy integrates with a wide range of CI/CD services, test automation frameworks, and code review tools through custom-built SDKs and client libraries.
Percy is designed for development and QA teams working on web and native applications. It is now part of BrowserStack, and users can sign up through BrowserStack to get started, with a free tier available for initial use.
