UI Flows is a new robotic process automation capability in Microsoft Power Automate that allows automating tasks in desktop and web applications. It is targeted at applications without strong APIs by storing automation scripts in the cloud to integrate UI-based automation with API-based automation. UI Flows is currently in preview and expected to be generally available in the first half of 2020. It uses Windows UI Automation for desktop apps and Selenium for web apps. UI Flows can run attended in a user session or unattended on a separate machine and requires Windows 10, Chrome/Edge, and other setup preparations. It fills a gap by allowing macros to run in the cloud for applications that lack APIs.
