FreeBSD is a Reliable and Secure Open-Source Operating System ➤ Download Now!

FreeBSD is an advanced computer operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years.

Its advanced networking, security, and storage features have made this platform of choice for many of the busiest websites and most pervasive embedded networking and storage devices.

FreeBSD includes kernel support for stateful IP firewalling, as well as other services. Such as IP proxy gateways, access control lists, mandatory access control, jail-based virtual hosting, and cryptographically protected storage.

FreeBSD also includes support for encryption software, secure shells, Kerberos authentication, “virtual servers” created using jails, chroot-ing services to restrict application access to the file system, and Secure RPC facilities. And in addition the access lists for services that support TCP wrappers.

FreeBSD Features:

  • Internet services. Many Internet Service Providers (ISPs) find FreeBSD ideal, running WWW, Usenet news, FTP, Email, and other services. Ready-to-run software like the Apache web server or the ProFTPD FTP server makes it easy to set up a business or community-centered ISP.
  • X Window workstation. Free X software (X.Org) comes with the system. nVidia offers native drivers for their high-performance graphics hardware, and the industry standard Motif and OpenGL libraries are supported. Both the KDE and GNOME desktop environments enjoy full support. Also provides office suite functionality, with further good functionality available in the OpenOffice.Org and TextMaker products.
  • Networking. From packet filtering to routing to name service, FreeBSD can turn any PC into an Internet firewall, email host, print server, PC/NFS server, and more.
  • Software development. A suite of development tools comes with included the GNU C/C++ compiler and debugger. You can also choose from a wide range of popular and powerful editors, such as XEmacs and Vim.
  • Net surfing. A real UNIX workstation makes a great Internet surfboard. Firefox and Opera are available for serious web users. Surf the web, publish your web pages, read Usenet news, and send and receive email on your desktop.
  • And much more. Accounting, action games, MIS databases, scientific visualization, video conferencing, Internet relay chat (IRC), home automation, multiuser dungeons, bulletin board systems, image scanning, and more are all real uses for this OS today.

Cutting edge features

FreeBSD offers advanced networking, performance, security, and compatibility features today which are still missing in other operating systems, even some of the best commercial ones.

Powerful Internet solutions

FreeBSD makes an ideal Internet or Intranet server. It provides robust network services under the heaviest loads. And uses memory efficiently to maintain good response times for thousands of simultaneous user processes.

Run a huge number of applications

The quality of FreeBSD combined with today’s low-cost, high-speed PC hardware makes this operating system a very economical alternative to commercial UNIX workstations. It is good for a great number of both desktop and server applications.

Easy to install

You can install this OS from a variety of media including CD-ROM, DVD-ROM, floppy disk, magnetic tape, and an MS-DOS partition. Or if you have a network connection, you can install it directly over anonymous FTP or NFS. All you need are these directions.

Free to use

FreeBSD is available free of charge and comes with full source code. If you would like to purchase or download a copy to try out, more information is available.

Minimum Hardware Requirements

Hardware architectures and devices supported by a FreeBSD release are listed on the Release Information page. The download page also has recommendations for choosing the correct image for different architectures.

An installation requires a minimum of 96 MB of RAM and 1.5 GB of free hard drive space. However, such small amounts of memory and disk space are only suitable for custom applications like embedded appliances. General-purpose desktop systems need more resources. 2-4 GB RAM and at least 8 GB hard drive space is a good starting point.

A summary of this information is given in the following sections. Depending on the method you choose to install FreeBSD, you may also need a supported CDROM drive, and in some cases a network adapter.


i386 requires a 486 or better processor and at least 64 MB of RAM. At least 1.1 GB of free hard drive space is needed for the most minimal installation.

Note: On old computers, increasing RAM and hard drive space is usually more effective at improving performance than installing a faster processor.


There are two classes of processors capable of running amd64. The first are AMD64 processors, including the AMD Athlon64, AMD Athlon64-FX, AMD Opteron or better processors.

The second class of processors that can use amd64 includes those using the Intel EM64T architecture. Examples of these processors include the Intel Core 2 Duo, Quad, and Extreme processor families, the Intel Xeon 3000, 5000, and 7000 sequences of processors, and the Intel Core i3, i5, and i7 processors.

If you have a machine based on an nVidia nForce3 Pro-150, you must use the BIOS setup to disable the IO APIC. If you do not have an option to do this, you will likely have to disable ACPI instead. There are bugs in the Pro-150 chipset for which we have not yet found a workaround.

PowerPC Apple Macintosh

All New World Apple Macintosh systems with built-in USB are supported. SMP is supported on machines with multiple CPUs.
A 32-bit kernel can only use the first 2 GB of RAM. FireWire® is not supported on the Blue & White PowerMac G3.


Systems supported by sparc64 are listed in the sparc64 Project.
A dedicated disk is required for sparc64. It is not possible to share a disk with another operating system at this time.
