Microsoft Team Foundation Server (TFS) is a collaboration tool for software projects that are jointly planned, created, and then managed. TFS is the unofficial successor of Microsoft's Visual SourceSafe. To work together on a software project, TFS supports various development processes, including CMMI, agile software development, and Scrum. For the work, TFS links and integrates familiar Office programs such as Word and Excel, so you don't have to switch from TFS to another program.
Various features are available for continuous integration, delivery, and deployment to help you build a pipeline. TFS basically separates the entire process into the version control, build, reports, and user administration sections.
Teams with a maximum of 5 people can use the free Express version; all larger teams have to use the commercial version, which costs about $6 per user per month. However, this usually requires you to purchase a server license. You can also purchase TFS without a monthly subscription, but you must contact a local reseller. The price seems to fluctuate between $570 and $800.
