If you only need a bare minimum, and don’t plan to heavily use CI/CD, container/packages registries, integrations with other tools i would go with gitea/forgejo (you can always use external tools on top), else i would use selfhosted Gitlab, it has pretty much all the things you could imagine to need with software development and deployment

i miss old plex (~2016), when it was actually focused on providing local content, good thing jellyfin exist
