Percy, a visual testing platform, has become the first and only one to support cross-browser testing on actual physical mobile devices. Currently, it supports iOS on Safari and Chrome on Android, with more combinations coming soon. To use this feature, users need to upgrade their plan to 'Percy Desktop & Mobile' or book a demo. Percy has also launched a separate mobile plan for its customers. The platform is built on BrowserStack's infrastructure, which allows it to support all major desktop browsers and now mobile browsers as well. Percy aims to make visual testing simple and accessible for all developers while continuously adding new features.
