Team Foundation Server (TFS) is the on-premises version of Azure DevOps, providing Git and version control hosting, continuous integration, agile planning (issues, Kanban, Scrum, dashboards) and release management for continuous delivery to the cloud and on-premises.
TFS provides a set of collaborative software development tools that integrate with your existing IDE or editor, enabling your cross-functional team to work effectively on software projects of all sizes. TFS combines activities such as Source Control Management, Work Item Tracking, Project Management, Build Management, and Reporting into a single product with strong integration points to the Visual Studio and Microsoft Office product lines.

Additionally, the rich API and extensibility points of TFS allows for custom applications and plug-ins to be created to customize TFS beyond the standard clients and server actions.
TFS and VSTS are highly related, sharing the same code base and most features, with the differentiator being TFS is the on-premise version, while VSTS is the hosted, software-as-a-service offering. Upcoming TFS features are usually made available in VSTS before being released in a quarterly update.
