These are some tools particularly useful for SE education, built by the same team behind se-education.org (i.e. sister projects).
RepoSense is a contribution analysis tool for Git repositories. It is particularly useful for those who want a chronological visualisation of the code contributions and commits made to a group of repositories. For example, educators can use RepoSense to track the progress of student projects and to examine the code written by each student.
RepoSense is available at https://reposense.org

TEAMMATES is available at http://teammatesOnline.info
