Unlike other repository analytics tools, Gitwiser supports three commonly used version control systems: Git, SVN (Subverison) & TFVC.
You should install a SCM addon and define your data sources in order to analyze your own repositories.
Addons for Git analysis: Azure DevOps, Bitbucket Server, Bitbucket Cloud, GitHub, GitLab.
Addons for SVN analysis: Svn (Subversion)
Addons for TFVC analysis: Azure DevOps (also supports old versions of TFS).
