The OpenFOAM repository migration to GitLab is now complete! Following the release announcement for v2506, all core OpenFOAM repositories have been successfully moved from the legacy platform at https://develop.openfoam.com to their new home at https://gitlab.com/openfoam.
All core OpenFOAM repositories are now accessible at https://gitlab.com/openfoam/core/openfoam. Users can create GitLab accounts to access repositories, submit issues, and contribute merge requests.
This transition marks an important step forward in community collaboration. The GitLab platform provides enhanced tools for version control, merge requests, and code review workflows, making it easier for contributors worldwide to participate in OpenFOAM development.
To begin working with the new repository location, update your remote URLs and create a GitLab account if you plan to contribute. While user associations from the previous platform could not be fully migrated due to account naming conflicts, creating a new GitLab account is straightforward and provides immediate access to all repository features.
