We host an instance of Gitea for all of our members. The UI and workflow of Gitea are very similar to GitHub. Gitea is currently home to most CSC software projects, including the code for this website.
For more information, see this page on our wiki.
We also host an instance of drone.io for CI/CD. To use Drone, you need to login to Gitea first. You can then selectively enable CI on your repos from the Drone UI. See the Drone documentation for more information.
