GitLab is a web-based Git repository manager similar to GitHub. GitLab can be self-hosted and we do just that with https://gitlab.opengeosys.org. For the moment all OGS repositories are still hosted at github.com/ufz but we store benchmark data files on our own GitLab because of storage limits on GitHub.
Request access. We will then give access to the repo. If the button is not there we already gave you access.
