This category lists operating systems (OSs) based on closed source code. Some such OSs have open source variants (BeOS, DOS, Unix, VMS), or straddle these two licensing models (QNX). Closed Source computer programs, including OSs, are those that include no source code, and for which the source code is kept secret, or made available only for a fee, as in many realtime OSs.
