Peer review is an important component of student development. As such, systems have been developed to support teachers in facilitating peer review. A key feature is double-blind review, were the reviewer and reviewee remain anonymous to each other. As more courses adopt Git along with a platform like GitHub, an interesting challenge emerges-all changes are tracked along with the identity of the student and it is not obvious how to conduct double-blind peer review. While external systems can be used, we believe it is more authentic for students to conduct their peer review within the environment provided by platforms such as GitHub, and less of an administrative burden for teachers. This paper presents our extension to RepoBee that facilitates double-blind peer review with minimal effort on the GitHub, GitLab and Gitea platforms, as well as the results of an informal study of teachers using it in their practice.
