Azure DevOps Timeline/Roadmap Native Function

Currently, Azure DevOps does not offer a native "timeline" or "roadmap" view that displays Epics individually as rows vertically and Sprints horizontally without using an extension. The Feature Timeline and Epic Roadmap extensions, which provided similar functionalities, have been deprecated

However, you can use the Delivery Plans feature in Azure DevOps, which allows you to visualize work items across multiple teams and projects on a calendar view. While it may not provide the exact vertical rows for Epics and horizontal columns for Sprints, it can help you manage and track progress across iterations
