FreeBSD
A mature open-source Unix-like operating system with a fully open kernel codebase. It is widely used in servers, embedded systems, and the underlying layers of gaming consoles, and is known for its stability and security.
Timeline (last 90 days)
NetBSD, unlike FreeBSD, does not have a large number of commercial deployments in the server market, nor is it known for security auditing like OpenBSD.
FreeBSD is an open-source Unix-like operating system whose kernel code is fully public.
The underlying system of the PS5 is based on FreeBSD.
The PS5 uses an operating system customized based on FreeBSD.
Anthropic disclosed multiple vulnerabilities, including a long-standing flaw in the FreeBSD network stack.
Some community users share the same commercialization concerns about TrueNAS, and some even plan to abandon TrueNAS in favor of native FreeBSD solutions.
kqueue originated in FreeBSD and works through two system calls, kqueue and kevent, with kevent handling both registration and event retrieval
Sony PlayStation's operating system, Orbis OS, is derived from FreeBSD 9.0.
The signal SIGBUS is numbered 7 on Linux and 10 on FreeBSD.
Netflix's global content delivery network is built on a heavily customized version of FreeBSD, and a single server has achieved TLS-encrypted traffic throughput of over 400 Gbps.

50%UnverifiedThe EI_OSABI field in the ELF header is used to identify the target operating system; FreeBSD sets it to ELFOSABI_FREEBSD (value 9), while Linux typically uses ELFOSABI_NONE or ELFOSABI_LINUX.
50%UnverifiedThe system call number for the open syscall is 2 on Linux x86-64, while it is 5 on FreeBSD.
50%UnverifiedThe error code EAGAIN has a value of 11 on Linux and 35 on FreeBSD.
50%UnverifiedFreeBSD's Linuxulator acts as a translation layer within the FreeBSD kernel to allow Linux software to run on FreeBSD, and after nearly two decades of development it can run complex Linux applications such as Steam and Chrome.

50%UnverifiedBoth Linux and FreeBSD use ELF as their executable file format, but the true compatibility barrier lies in differences in the system call interface (syscall ABI).
50%UnverifiedBSDun is an open-source project whose goal is to add native support for FreeBSD ELF binaries to the Linux kernel, allowing FreeBSD programs to run on the Linux kernel without recompilation.
50%UnverifiedOPNsense is the more actively maintained community fork of pfSense (based on FreeBSD); both are open-source firewall/router operating systems that support VLAN segmentation.
