Several people and projects use CentOS or Red Hat Enterprise Linux as a base within which to build additional functionality. We note them alphabetically.


These products are NOT CentOS. This list is merely provided as a public service. Some may well be a downstream fork.

Note that this page is *grossly* out of date, and many of the projects/products on this page no longer exist. You can help by editing this page and verifying the status of various things listed here.

Finally, CentOS' upstream has had a long term marketing relationship with Amazon.

Hence, ask **them** if you break something.

<!> Domain expired on 2019-11-14 01:04:50 (last checked: Sun 24 Nov 2019 05:57:24 PM UTC)

Whitebox Enterprise Linux was based on Red Hat Enterprise Linux. Its goal was to provide an unencumbered binary RPM based Linux distribution. Only EL3 and EL4 images were built during this project's life. It became unsupported when its maintainer was affected by the US Katrina Hurricane in 2005, the underlying distributions updates SRPMs went 'end of life', and is now largely of historical interest.

<!> The text on this page is largely quoted from those projects, along with the links cited, and do not necessarily represent the opinions of CentOS.
