Linux is a free software kernel, which combined with the GNU libraries, core utils and shell form the GNU/Linux operating system.

Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian uses the Linux kernel (the core of an operating system), but most of the basic OS tools come from the GNU project; hence the name GNU/Linux.

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.

Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.

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]

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.

MidnightBSD is a desktop operating system for ia32 and amd64/emt64 computers. It uses GNUstep and related software to provide an easy to use environment.

µClinux is a Linux distribution like any other Linux distribution, focused on embedded projects, built from the Linux kernel from kernel.org and assorted other packages, and software from the GNU project. Since µClinux is optimized for size, it ... [More] uses more compact alternatives (busybox, µclibc, etc) than a non-embedded distribution. Pronounced "you-see-linux", the name µClinux comes from combining the greek letter "mu" and the english capital "C". "µ" stands for "micro", and the "C" is for "controller". µClinux supports embedded processors which support MMU (protection and virtual memory support), noMMU (no protection, no virtual memory) and MPU (memory protection, but no virtual memory support). The µClinux-dist includes userspace apps & libs, toolchain, c library, kernel and Bootloader. [Less]

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]

Quarn OS is an operating system written in C and x86 assembler. All its parts are distributed under terms of open source licenses (mainly GNU GPL v2 or later). Previously designed as monolithic kernel, currently aims at modified conception of ... [More] hybrid kernel. One of the main goals in Quarn development is to make it compatible with Single UNIX Specification, so it will be possible to execute programs written for other UNIX-like systems. Quarn OS uses additional subproject: Managed Execution System, which is used to provide universal interface. [Less]
