Projects

Debian GNU/Linux

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

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, (32-bit and 64-bit) MIPS and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of ... [More] California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development. [Less]

ReactOS

The ReactOS® project is a ground-up implementation of a Microsoft Windows® XP/2003 compatible operating system. ReactOS aims to achieve complete binary compatibility with both applications and device drivers meant for NT and XP operating systems, by using a similar architecture and providing a ... [More] complete and equivalent public interface. Written completely from scratch, ReactOS is not a Linux based system, and shares none of the UNIX architecture. The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow your Windows® applications and drivers to run as they would on your Windows system. [Less]

AROS

The AROS Research Operating System is a lightweight, efficient and flexible desktop operating system, designed to help you make the most of your computer. It's an independent, portable and free project, aiming at being compatible with AmigaOS 3.1 at the API level (like Wine, unlike UAE), while ... [More] improving on it in many areas. The source code is available under an open source license, which allows anyone to freely improve upon it. [Less]

Syllable operating system family

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 multitasking, high POSIX compliancy, 64-bit ... [More] 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]

Canaima GNU/Linux

Canaima GNU/Linux, la metadistribución venezolana, es un sistema operativo libre y de estándares abiertos basado en el sistema de paquetes APT y de propósito general enfocado a las necesidades del Estado Venezolano. El proyecto Canaima también involucra la plataforma de desarrollo, orientada ... [More] hacia la integración de esfuerzos de usuarios, desarrolladores e instituciones nacionales y regionales. [Less]

pmbsd

The Pigeon Mouette BSD project provides a FREE, multi-platform BSD UNIX-like operating system. PmBSD is 'what we think a BSD is' and was totally written from scratch. The only sources stolen by this project were stolen from OpenBSD and are a part of this website and the file sys/queue.h. ... [More] PmBSD is freely available from our mercurial repository. [Less]

yasux

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 achieved by keeping features away, but by ... [More] letting features be deactivateable, so the user can remove all features which he does not want. [Less]

FabBSD

A special-purpose 4.4BSD-based UNIX-like operating system, designed for machine control applications. Using low-cost hardware, FabBSD can be used to control a wide array of CNC milling machines, lathes, routers, process-control and automation equipment.

monarc

Monarc Operating System KernelMonarc is an experimental and progressive operating system kernel; featuring modern architecture, clean code, and flexible structure. It is implemented in C/C++ and a small amount of assembly. The current platform is x86-32, and soon x86-64. You can see a screenshot of the early GUI here.
