The OpenBSD project maintains portable versions of many subsystems as packages for other operating systems. Because of the project's emphasis on code quality, many components are reused in other software projects. Android uses its C standard library,^[7] LLVM uses its regular expression library,^[8] and Windows 10 uses OpenSSH with LibreSSL.^[9]

The name OpenBSD refers to the availability of the source code on the Internet. It also refers to the wide range of hardware platforms the system supports.[10].
