   It is possible to run CI jobs (https://docs.gitlab.com/ee/ci/) on GitLab on certain events (like pushes or pull request creation).

While added as recently as 2023-02-27, Forgejo supports an integrated continuous integration system called Actions (https://forgejo.org/2023-02-27-forgejo-actions/). For specific purposes where a custom environment is required, even custom Forgejo runners (https://code.forgejo.org/forgejo/runner) can be associated with a certain project repository or project namespace.
