This page maintains a list of academic, personal, and small non-commercial operating systems. For information regarding commercial or main-stream operating systems visit Wikipedia.


The type of operating systems listed here have a high mortality rate. This list was off-line from 09-04-2004 until 06-17-2006 and during that time 112 of 213 operating system projects disappeared from the internet leaving only 101(submitted). Looking at how often these projects are started by using the OS Project Announcement forum we can see that between 11-24-2004 and 6-21-2006 around 68 projects were announced(many of which disappeared before being added here). The current total is 132 projects. Please help keep this list current by correcting it yourself if you have a login id or by posting a message on the OSDevWiki forum pointing out the incorrect entry.

  • BAB - BABy (Basic Abstraction Block) is a 50Kb IA-32 microkernel for DOS. It manages the x86 hardware interaction in a manner similar to Windows' HAL. BABy exports an extensive API via INT's 15h, 2Fh, and 31h. It is free LGPL'd software with full source. The API provides services in 5 categories: I/O control, PMode domains, PMode services, Memory mgmt, and VM86 mode. DPMI services via BAB are not yet complete. BABy can be used to provide PMode services to our shareware multiuser O/S, VMiX x86 (listed velow). Distribution includes binaries, sources, makefiles, samples and API docs.

  • BRiX - safe-language/OS hybrid - persistent database filesystem - reconfigurable graphical interface


C


  • Capital OS - Capital is an Object Oriented Operating System being developed for iPAX386+ processors. It features a multithreading tasking model. The kernel itself is multithreaded and is fully preemptible giving support for Real Time processes. The memory model is a paged virtual memory system. A hardware interface layer is envisaged. It follows a totally Object oriented design with all designing done in UML. It is being written in C++, C and of course, Assembly.



  • CapROS (The Capability-based Reliable Operating System) - CapROS is a new operating system that merges some very old ideas about capabilities with some newer ideas about performance and resource management. The result is a small, secure, real-time operating system that provides orthogonal persistence.



  • Caracal - Caracal started life as a hobby OS which was going to make it as far as a 'hello world' kernel. Since I got the OS Dev bug it has now grown to a multiboot compatible pmode32 OS with multitasking support. The next stage of development is going to be the addition of disk IO. It is also intended to create an OS of the same name for Atmel's AVR range of 8-bit microcontrollers.





  • Cleese - The goal is an operating system written as much as possible in Python with the Python VM as a micro-kernel on top of a minimal C/asm layer.



  • Clicker - Exploring new ways in OS design. Clicker32 is a microkernel-based system for x86 hardware. It's based on modular architecture and already supports preemptive multithreading + user-level processes. Next milestone (0.8.0) should allow loading of user program from another user program.

  • COPSY - COPSY stands for Cool OPerating SYstem, and is meant to be written in C++. Another C++ OS that will die?? Don't think so. COPSY will be built with a kernel made in C++/asm and have a framework of classes for rapid app dev. The first step will be to make a minimal binary containing a class, to get it work from the beginning.

  • Cosmos - A small OS built with NASM and DJGPP, plus lots of information on writing your own OS.



  • csertOS - csertOS is an os deesighned and built be CSERT. It is designed from the ground up to be as secure as possible


D


  • DarWin - GNU-Darwin aims to be the most free software distribution. Our mission is two-fold: Focus on projects that leverage our unique combination of Darwin and GNU, and help users to enjoy the benefits of software freedom.


  • Delta - A microkernel for x86 computers, ports to other architectures possible later. Aims for speed and simplicity (both in code and in usage).



  • DEX Extensible operating system (dex-os) - dex-os is an educational operating system that supports a plug-in like architecture and aims to achieve zero static inter-module calls.



  • DexOS - DexOS is a 32bit, asm OS, based on the idea, that it would be cool to have a OS based on a console type OS, but instead of running on a xbox or DS, it would run on a x86. From the start, as you would expect from a OS based on a game's console OS, optimizing for speed has been of paramount important in the over all design. To this end there's no virtual memory, paging, and only a single process is allowed (though that process can spawn multiple threads). The program runs in ring0, you have direct access to all hardware (including CPU and graphics). Memory allocation is the responsibility of the app--there's no front-end memory allocation. The entire OS will fit into less than 100k.

  • eox3 - eox3 is planned to be a RT SMP microkernel. I finally decided to publish a link in here, though my kernel is far away from being useful. The project is currently paused, as I've no time for coding till at least October03 + I somehow lack motivation since a few years.. :(. Maybe some nice responses will get rid of this problem.. Don't expect anything, just another hobby os.

  • MazzanetOS - MazzanetOS is a DOS/UNIX-like operating system written in assembly language and C++. It currently runs off a floppy disk and includes a graphics demo. It will run (hopefully) on any PC.



  • MegaOS - This is a project to create a new POSIX compliant Unix clone(gnu gpl). The goals of Mega OS are as follows, to be as stable, secure, and easy to use as possible, and also if possible without undermining any of the previous goals, to be fast and efficient.



  • MenuetOS - MenuetOS is a fully 32 bit assembly written graphical operating system. Menuet supports 32 bit x86 assembly programming as a faster and smaller system footprint. Menuet has no unix roots and the basic system is meant to be a clean asm based structure. Menuet isn't based in any particular operating system, since the idea has been to remove the extra layers between different parts of software, which complicate programming and create bugs. Menuet's application structure is not specifically reserved for asm programming since the header can be produced with practically any other language. However, the overall application programming design is intended for easy 32 bit asm programming. The GUI is extremely easy to handle with assembly language.



  • Micro OS X - A Free DOS like Operating System which fits on one floppy disk. The new Micro OS X is the third generation of Micro OS. The Micro OS X Workspace Manager is based on GEM Desktop.

  • MOS - Mother Operating System is a Multi-User, Multi-Process Operating System written in “C” language. Currently, MOS is designed to run on x86 architecture. It is a 32 bit protected mode OS. It uses x86 TSS architecture to support multi tasking. System calls are implemented using Call Gates. Exceptions and IRQs which need their own stack and can run across process task switches are handled through task gates in IDT and others are handled through normal interrupt gates. The aim is to have its users a pleasant experience using MOS.



  • Mort - Mort is a multitasking UNIX like operating system for x86 compatibles, similar in design to the Linux kernel. Mort is a hobby of mine and is still in its early stages of development. Eventually it is planned that Mort will have it's own Graphical User Interface, TCP/IP implementation, and other useful things.

  • Oberon System - The Oberon System is an academic operating system which was developed by Niklaus Wirth and Jürg Gutknecht in the second half of the 1980s. It is available from Native Oberon and a more current multiprocessor version can be found here: BlueBottle. Note that some stuff on these pages appear outdated, but it appears to be more the problem of keeping the Web-pages as current as the System. An active mailing list is here: Oberon Mailing List Archive. More current and in depth documentation is included in the systems, although you (sorrily) have to master their (partially) unconventional user-interface before you can access the documentation. A kind of an henn and egg problem.

Sendla OS is going to have a major security system running, this will not, like windows, prevent the user himself from being restricted, an included antispyware engine will also be running. We are also adding 3 modes of use with it for ease of use without restriction ( Beginner, Advanced and Command). Beginner is just simply a click to start your program type interface. Large buttons with pictures of their software on them will be used to make an extremely simple interface. Advanced mode will be more like the current Windows GUI, but much more stable and enhanced. Command mode as youve probably guessed by now is a DOS like shell. Type the command to run somthing, this has a similarity to the restriction free linux.

  • SysPak OS - SyaPak OS is a microkernel based multiprocessor, multitasking, multithreading operating system for the IBM-PC Intel i386 systems. It is developed in Department of Computer Science of Bahahuddin Zakariya University, Multan Pakistan, under the kind supervision of Dr. Aman Ullah Khan. SysPak OS is a operating system with an emphasis on design and portability. It is largely implemented in C/C++, with a small amount of assembly. Currently, the system is mostly a kernel with a minimal amount of user space libraries and applications. Thus far, most of the work has been put into the kernel and other underlying support. As a result the system isn't that interesting from an end-user point of view (no gui, simple commands on a command line). Full documentation is available.
