A BSD operating system built for servers, networking, and storage.

FreeBSD is a free, open source Unix-like operating system with a long-running community project behind it. The site provides downloads, release notes, security advisories, documentation, source repositories, community links, and project updates for users and contributors.

Why it stands out

  • Combines a complete operating system, documentation project, ports collection, and development community under one long-running project.
  • Treats documentation as a core project artifact, with the Handbook, manual pages, and specialist guides prominently maintained.
  • Includes FreeBSD-specific infrastructure features such as jails, bhyve, and tightly integrated OpenZFS.
  • Maintains visible release engineering, security advisory, errata, and status-report channels from the main site.

Good to know

  • Useful only if you are prepared to install and administer a full operating system, not a single application or web service.
  • The main download area highlights architecture-specific releases, so users need to choose the correct image for their hardware.
  • Advanced features such as jails, ZFS, and bhyve assume comfort with system administration concepts.

Under the radar: Before upgrading a system, check both the Security Advisories and Errata Notices sections; errata can include important non-security fixes that are easy to miss if you only watch security updates.
