Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 5476, "days_push": 7, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
The official publish-only Git mirror of the FreeBSD source tree, containing the complete kernel, userland, libraries, boot loader, and build system for the FreeBSD operating system. FreeBSD is a mature, UNIX-like open-source operating system derived from BSD, developed continuously for over thirty years and known for advanced networking, ZFS storage, jails, and the bhyve hypervisor.

## Use cases
- build a custom FreeBSD kernel or full world from source
- contribute a patch or pull request to FreeBSD
- port FreeBSD to a new ARM or embedded board
- study operating system kernel and networking stack implementation
- set up a high-performance server with ZFS and jails
- build a network appliance or router on a BSD base
- audit the source of a production operating system

## When to choose
- you need a stable, well-documented UNIX-like OS for servers, network infrastructure, or embedded devices
- you want native ZFS, jails, or bhyve virtualization
- you need to build, customize, or cross-build the entire OS from source
- you want permissive BSD licensing for a commercial or embedded product

## When to avoid
- you need a desktop-first OS with broad consumer hardware and gaming support
- you want a Linux-based ecosystem with mainstream package and driver compatibility
- you only need prebuilt binaries - use official release images instead of the source tree
- your team has no C/systems experience and needs an easy-to-modify platform
