Sonatype Nexus Repository

Sonatype Nexus Repository is a software repository manager, available under both an open-source license and a proprietary license. It can combine repositories for various programming languages, so that a single server can be used as a source for building software. The open source version uses the H2 database.
Alternatives to Nexus include JFrog Artifactory.

History

Tamás Cservenák originally developed Proximity in 2005, because he had a slow ADSL internet connection. He was later hired by Sonatype to build a similar product, Nexus.
