Xinuos is an American software company that was created in 2011 and was first called UnXis until assuming its current name in 2013. (Both names have been variations on the spelling of the Unix operating system.) Xinuos develops and markets the Unix-based OpenServer 6, OpenServer 5, and UnixWare 7 operating systems under SCO branding, as well as the newer OpenServer 10 operating system.
