You need a place to host your private Java artifacts (or Rubygems, NuGet, Docker, Npm, etc.)? You can use Artifactory or Nexus, but you will most likely have to pay for them. Instead, check
Artipie (I'm one of its developers and it's open source). It's in beta-testing mode now and it's free for everybody. You heard it right: you can host your private artifacts for free! However, it's for good people only. To get an account there you have to come to our chat and ask for access:
