    GhostBSD

    GhostBSD provides a simple desktop-oriented operating system based on FreeBSD with MATE, OpenRC and OS packages for simplicity. GhostBSD has a selection of commonly used software preinstalled and required to start using it to its full potential. GhostBSD uses the GTK environment to provide a beautiful looks and a comfortable experience on the modern BSD platform offering a natural and native Unix work environment. GhostBSD is built on top of FreeBSD code, and its roots go back to the University of California Berkeley Unix Research. Historically it was referred to as "BSD Unix" or "Berkeley Unix." However, today it is called BSD for Berkeley Software Distribution. The project goal is to combine security, privacy, stability, usability, openness, freedom and to be available for everybody free of charge. The user experience is further enhanced by tools like the Networkmgr which are developed as part of the GhostBSD project.

    DragonFly BSD

    DragonFly BSD

    DragonFly BSD

    DragonFly version 6.2.2 is released. The 6.2 series has hardware support for type-2 hypervisors with NVMM, an amdgpu driver, the experimental ability to remote-mount HAMMER2 volumes, and many other changes. DragonFly belongs to the same class of operating systems as other BSD-derived systems and Linux. It is based on the same UNIX ideals and APIs and shares ancestor code with other BSD operating systems. DragonFly provides an opportunity for the BSD base to grow in an entirely different direction from the one taken in the FreeBSD, NetBSD, and OpenBSD series. DragonFly includes many useful features that differentiate it from other operating systems in the same class. The most prominent one is HAMMER, our modern high-performance filesystem with built-in mirroring and historic access functionality. Virtual kernels provide the ability to run a full-blown kernel as a user process for the purpose of managing resources or for accelerated kernel development and debugging.

    OpenBSD

    OpenBSD

    OpenBSD

    OpenBSD is developed entirely by volunteers. The project's development environment and developer events are funded through contributions collected by The OpenBSD Foundation. Contributions ensure that OpenBSD will remain a vibrant and free operating system. Hence the OpenBSD project has embedded cryptography into numerous places in the operating system. We require that the cryptographic software we use be freely available and with good licenses. We do not directly use cryptography with nasty patents. We also require that such software is from countries with useful export licenses because we do not wish to break the laws of any country. Be as politics-free as possible; solutions should be decided on the basis of technical merit.

    MidnightBSD

    MidnightBSD

    MidnightBSD

    It includes all the software you'd expect for your daily tasks — email, web browsing, word processing, gaming, and much more. With a small community of dedicated developers, MidnightBSD strives to create an easy-to-use operating system everyone can use, freely. Available for x86, AMD64 and as Virtual Machines. The FreeBSD project has developed a reliable server operating environment, but often usability and performance on the desktop is overlooked. Scheduling, allocation of resources, security settings, and available application support should be tailored to desktop users. Many of the BSD projects are tailored to servers or older hardware. Others are distributions of FreeBSD with a nice graphical user interface, but still suffer from server-centric design under the hood. We did not fork FreeBSD as a result of a falling out, but rather as an excellent starting point.

    NetBSD

    NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. NetBSD was originally released in 1993. Over time, its code has found its way into many surprising environments, on the basis of a long history of quality, cleanliness, and stability. The NetBSD code was originally derived from 4.4BSD Lite2 from the University of California, Berkeley. NetBSD is an entirely free and open-source UNIX-like operating system developed by an international community. It isn't a "distribution" or variant but has evolved over several decades to be a complete and unique operating system in the BSD family. NetBSD users enjoy a simple, well-documented, and fully integrated UNIX-like system that feels minimal, and in many ways traditional, while including many modern and interesting features, and support for recent hardware.

    NomadBSD is a persistent live system for USB flash drives, based on FreeBSD®. Together with automatic hardware detection and setup, it is configured to be used as a desktop system that works out of the box, but can also be used for data recovery, for educational purposes, or to test FreeBSD®'s hardware compatibility. The images for 64-bit and 32-bit computers fit on a 5GB USB flash drive. A system with a 1.2GHz CPU and 1G of RAM should be able to run NomadBSD decently. Booting is possible via BIOS and UEFI. We've decided to change the versioning scheme to the following form: FFfX-YYYYMMDD, where FF is the major two-digit FreeBSD version, f is the minor version, and X stands for ALPHA (A), BETA (B), RC, or RELEASE (R). Followed by a date. The new scheme allows us to provide images with different version of FreeBSD.

    openIndiana

    OpenIndiana is an operating system from and for the illumos community, it branches from the UNIX-derived family tree, and as such it can sometimes seem quite complex. But with a little help and information, once you know the basics, you will find it actually has some of the nicest and friendliest tools around. As most Unix-derived operating system, it can be completely controlled via a Command Line Interface shell, but it also supports a windowing GUI system. From the CLI, it supports a number of different shells, the two main ones being ksh93 and Bash. It also supports the original SunOS SVR4 commands, the command and syntax famiilar to BSD users, and a large portion of the GNU userland commands that most Linux users are familiar with. You can select any or all of those different commands from your shell configuration, giving you the environment you are most happy with.

    FreeBSD Jails
    Since system administration is a difficult task, many tools have been developed to make life easier for the administrator. These tools often enhance the way systems are installed, configured, and maintained. One of the tools which can be used to enhance the security of a FreeBSD system is jails. Jails have been available since FreeBSD 4.X and continue to be enhanced in their usefulness, performance, reliability, and security. Jails build upon the chroot(2) concept, which is used to change the root directory of a set of processes. This creates a safe environment, separate from the rest of the system. Jails improve on the concept of the traditional chroot environment in several ways. In a traditional chroot environment, processes are only limited in the part of the file system they can access. The rest of the system resources, system users, running processes, and the networking subsystem are shared by the chrooted processes and the processes of the host system.

    syzkaller
    syzkaller is an unsupervised coverage-guided kernel fuzzer. Supports FreeBSD, Fuchsia, gVisor, Linux, NetBSD, OpenBSD, and Windows. Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well. Once syzkaller detects a kernel crash in one of the VMs, it will automatically start the process of reproducing this crash. By default, it will use 4 VMs to reproduce the crash and then minimize the program that caused it. This may stop the fuzzing, since all of the VMs might be busy reproducing detected crashes. The process of reproducing one crash may take from a few minutes up to an hour depending on whether the crash is easily reproducible or non-reproducible at all.

    Sphinx

    Sphinx

    Sphinx

    Sphinx is an open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind. It's written in C++ and works on Linux (RedHat, Ubuntu, etc), Windows, MacOS, Solaris, FreeBSD, and a few other systems. Sphinx lets you either batch index and search data stored in an SQL database, NoSQL storage, or just files quickly and easily, or index and search data on the fly, working with Sphinx pretty much as with a database server. A variety of text processing features enable fine-tuning Sphinx for your particular application requirements, and a number of relevance functions ensures you can tweak search quality as well. Searching via SphinxAPI is as simple as 3 lines of code, and querying via SphinxQL is even simpler, with search queries expressed in good old SQL. Sphinx indexes up to 10-15 MB of text per second per single CPU core, that is 60+ MB/sec per server (on a dedicated indexing machine).
