GitLab released integrated packaging back in 2016 - starting with a Docker registry - and adding Maven and NPM in 2018. You can find our plans for adding further packaging capabilities on our public packaging roadmap https://about.gitlab.com/direction/package/

We are also embarking on making package management more secure and auditable for the users of packages with a Dependency Proxy https://about.gitlab.com/direction/package/dependency_proxy/ GitLab users will be able to block and delay packages that are suspect and trace where vulnerable packages were used. This will increase performance, cost efficiency, and the stability of your tests and deployments.
