OpenCSW

The Open Community Software Project (OpenCSW) is an open-source project providing Solaris binary packages of freely available or open-source software.

It is an Association in terms of Article 60-79 of the Swiss Civil Code with domicile in Greifensee/ZH, Switzerland. The purpose of the association is to provide software packages that run on currently supported production versions of the Solaris Operating Environment. It was founded as a fork by former members of the "CSW" packaging project, previously hosted at Blastwave. The Blastwave project is now defunct.

OpenCSW provides packages for Solaris 9, 10, and 11 (by compatible Solaris 10 packages) for 32 and 64-bit, x86 and SPARC architectures. Solaris 8 is no longer a 1st-class supported OS, however, there still exists a legacy Solaris 8 archive.
