Much of FreeBSD's codebase has become an integral part of other operating systems such as Darwin (the basis for macOS, iOS, iPadOS, watchOS, and tvOS), TrueNAS (an open-source NAS/ SAN operating system), and the system software for the PlayStation 3 and PlayStation 4 game consoles. A wide range of additional third-party applications may be installed from binary packages using the pkg package management system or from source via FreeBSD Ports, or by manually compiling source code.Īs of 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed and permissively licensed BSD systems.
