Crest is released as open source software and comes with no commercial support.

But since we want to ensure success and recognize that Crest consumers might fall into a range of roles - from developers that are steeped in the conventions of open-source to customers that are more accustomed to VMware commercial offerings, we offer several methods of engaging with the Crest team and community.
