FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX ... [More] developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development. [Less]

OpenSolaris is an open source project created by Sun Microsystems to build a developer community around the Solaris Operating System technology.

The goal of the Syllable project is to create a family of easy-to-use free software operating systems. It is the continuation of the BeOS-like AtheOS. Syllable Desktop has its own C kernel with symmetric multiprocessing, multithreaded pre-emptive ... [More] multitasking, high POSIX compliancy, 64-bit journaled filesystem (AFS) with metadata, an integrated native GUI architecture with an object-oriented C++ API, SDL, singular native toolkit and multi-user desktop environment. The system seeks to be an integrated, lightweight, easy-to-program, powerful, high-performance graphical desktop environment which avoids legacy OS paradigms that frustrate developers and have hindered the computing masses' adoption of a free-software desktop. Syllable Server is a matching small and efficient Linux server. [Less]

The HelenOS project is an effort to develop a complete and usable modern operating system, yet offering room for experimenting and research. HelenOS uses its own microkernel written from scratch and supports SMP, multitasking and multithreading on ... [More] both 32-bit and 64-bit, little-endian and big-endian processor architectures, among which are AMD64/EM64T (x86-64), ARM, IA-32, IA-64 (Itanium), 32-bit MIPS, 32-bit PowerPC, SPARC V9 and Xen 3.0. Thanks to the relatively high number of supported architectures and suitable design, HelenOS is extremely-well portable. [Less]

DragonFly is an operating system and environment originally based on FreeBSD. DragonFly is developing a radically different approach to concurrency, SMP, and most other kernel subsystems. DragonFly belongs to the same class of operating system as BSD and Linux and is based on the same UNIX ideals and APIs.

CleanOS is an operating system developed for educational purposes, initially to be an userspace GNU/Linux application running its executables and simulating the operating system task scheduler and IPC mechanisms, perhaps later a true kernel.

Yasux ("Yet another simple UNIX") is yet another simple UNIX written from scratch. Its aim is to be a Single UNIX Specification compliant operating system being simple, small in its size and having a source which is easy to understand. This is not ... [More] achieved by keeping features away, but by letting features be deactivateable, so the user can remove all features which he does not want. [Less]

Symmetry is a small operating system written in C++. It aims to be platform independent and very fast. It currently has support just for the basic functions needed to run a computer - the GDT, IDT, and paging, as well as dynamic memory management and a simple virtual file system (VFS).

Hybrid is a kernel being developed with an emphasis on design and portability. It is largely implemented in C/C++, with a small amount of assembly. The kernel is built on top of elklib.
