FreeBSD vs. Linux: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 19, 2023
FreeBSD is a Unix-like operating system derived from BSD, while Linux is a Unix-like OS based on the Linux kernel.

Key Differences

FreeBSD is a free and open-source operating system derived from the original Unix through the Berkeley Software Distribution (BSD). Its development focuses on features, performance, and advanced networking. Linux, on the other hand, refers to an operating system based on the Linux kernel, which was created by Linus Torvalds. While both share Unix roots, their paths diverged in terms of development and licensing.

FreeBSD has its own complete base system, including the kernel and userland utilities, all maintained under a single umbrella. This holistic approach ensures consistency and tight integration. Linux is different in that the kernel and userland tools are often developed separately. Distributions like Ubuntu, Fedora, and Debian bring together the Linux kernel with software mostly from the GNU project to create a complete OS.

FreeBSD uses a different licensing model with the BSD license, which is permissive, allowing for both open and closed source derivatives. Linux primarily uses the General Public License (GPL), which mandates that derivatives remain open source. This fundamental difference impacts the way businesses and developers approach and use these systems.

The package management and port system in FreeBSD offers a unique method of software installation, while Linux distributions typically use package managers like APT, YUM, or Pacman. The FreeBSD Ports collection provides a straightforward way to compile and install third-party applications, whereas Linux distributions often have pre-compiled software repositories.
