What is FreeBSD? 

FreeBSD is a free Unix-like operating system descended from Research Unix via the Berkeley Software Distribution (BSD), also known as “Berkeley Unix.” Find out more about key features and applications here.

Who is Using FreeBSD?

Probably a lot more people than you think. FreeBSD is everywhere. In fact, there’s a good chance you’re using at least some code derived from FreeBSD in your everyday life. If you stream movies via Netflix, chat with friends on WhatsApp, or play the latest PlayStation 4 game sensation, you’re already using FreeBSD. That’s only the beginning though, take a look at just some of the companies and applications using FreeBSD.
