This is a separate, free tool from Microsoft that integrates with TFS and allows you to do pretty much everything you can do from VS, but in a web interface. You can create and modify work items as well as work item queries, see the reports and documents, and initiate and monitor builds. The only area with limited functionality is Source Control. You can see history and change-set details, but you can't check out/check in documents due to the web client nature.
