Percy.io is a web-based visual regression testing platform designed for development and QA teams to automatically detect unintended UI changes across web applications. It integrates directly into CI/CD pipelines, capturing UI snapshots across various browsers and responsive breakpoints. The platform then compares these new snapshots against an approved baseline, highlighting pixel-by-pixel and DOM-aware visual differences. Users interact with a dedicated web dashboard to review, approve, or reject these visual diffs, ensuring UI consistency and preventing visual regressions from reaching production environments.

Use Cases
For Developers
Preventing UI Regressions in Feature Branche
Developers integrate visual regression tests into their feature branch CI pipelines. Before merging, they review visual diffs to ensure their code changes haven't inadvertently altered the UI of other components or pages, catching visual bugs early in the development cycle
How to Use Percy.io
