 Autolab is an auto evaluation software for programming labs. The software currently supports automatic evaluation in Java, Python2, Python3, C++ and C programming languages. Autolab uses [Gitlab](https://gitlab.com/gitlab-org) as a component to provide the version control system. All the student code submissions reside in Gitlab, thus benefiting from powerful *git* system. The software is modular with separate microservice instances for all the application components.
