OSes have a high mortality rate: between 2004 and 2006, 112 of 213 OS Projects disappeared from the Internet. And looking at how often these projects are started by using the [[Forum:2|OS Project Announcement forum]], in that same time period 68 projects were announced! The current total is 175 projects, but just 58 of them are active (as of January 1, 2018) and only 62 have been updated at least once since 2018 (three of which have been since abandoned), and 27 since 2019. Please help keep this list current by correcting it if you see any outdated information. |
|||
OSes without an update since 2015 are now located at [[Abandoned Projects]].<br/> |

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 [[Forum:2|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 [[Forum:8|OSDevWiki forum]] pointing out the incorrect entry. |

More mature hobby operating systems can also be found at [[Notable Projects]].<br/> |

Particularly advanced and successful operating systems are listed at [[Advanced Projects]]. |

|OSDescription=Acess2 is a kernel and operating system designed to do what Linux does, be customizable to any given situation. However, unlike Linux, it there is no need to maintain backwards compatibility with anything. It features a simple but extensible VFS that currently supports VFAT and Ext2, IPv4/IPv6 networking with TCP/UDP, USB input, and storage. Recently, this project has been moved to GitHub, but its old git repo—with outdated sources and some useful documentation—can be found here: http://git.mutabah.net/?p=acess2.git;a=summary . v0.14 outdated floppy image is available at its' old page: username - root, password is blank. Could try building a new floppy from the latest sources by yourself! ''(some software rot has been noticed but its fixable)'' |

|OSDescription=The BlueKernel is a simple microkernel design intended for students. It has pre-emptive multitasking with threads, message-passing and virtual memory. It is currently targeted for the IA-32 processors, but the design is strictly separated into a hardware-dependent mechanisms layer, with an independent policy layer on top of that. It has its own basic boot loader that loads the kernel and a disk driver. It also has a basic text-mode display driver and keyboard driver. As with most microkernels, the drivers run in user space and help to demonstrate message passing and interrupts. When the system starts it loads a server that allows the user to load their own processes. There are very simple example user programs to demonstrate threads, message-passing and interrupts. The website is written like a textbook to explain how it all works, focusing on the implementation rather than theory. |

|OSDescription=BOS is a new 32-bit Operating System designed with DOS in mind. That means no protection, no multitasking, no paging, and no to a lot of other things often related with new 32-bit OS:es. But despite it's lack of protection it will still be a modern OS with native support for CD-ROM/BURNER, DVD, USB, most filesystems, up to 4gb of memory etc. This is a OS for all those people that miss the days of DOS programming. |

|OSDescription=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. |

|OSDescription=Fudge started as a project to see if it would be possible to create an operating system that came as close as possible to be fully deterministic by not implementing solutions with unpredictable behaviour like dynamic memory allocation, scheduling and caching. |

|OSDescription=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. |

|OSDescription=JSLK is a 32-bit hobby kernel designed to run on the x86 architecture (although portability has been taken into consideration). It was started in August 2017 with the objective of learning how a computer operating system works and to improve the coding skills of the main developer. The kernel is mostly written in C with some bits of assembly and has partial compatibility with C++ (a runtime is provided). Some of its features are: extensive HAL API, System V ABI compatibility, memory management, interrupt handling, VGA driver, timers and delays, some synchronization primitives, a growing home-made C library, virtual memory, a VFS, a keyboard and RTC driver and more.

|OSDescription=Horizon is a research Operating System. It is written for the i386 processor family, using C (gcc) and some Assembly (nasm). Its main goal is to develop a natively network-integrated structure, so that I/O operations (both local and network ones) happen in the same manner. This way every Horizon node on the Internet (or in a LAN) can communicate natively by means of a Network File System. |

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 |

It is designed to be easy to understand, and fairly lightweight (for example, it only requires 3MB of RAM to run on an x86). Currently only implemented for x86, but it should be easy to port to other platforms. Has a preemptive kernel which allows dynamic loading of kernel modules, and supports page replacements and a dynamically linked kernel-to-usermode API. Current working on implementing more of the C POSIX library. |

|OSDescription=NexNix is designed to be a powerful, safe, and modern operating system. It aims to take Unix and greatly improve on it, by making the filesystem more structured, being a true microkernel, implementing modern security measures, and being more GUI-centric. It still aims to be compatible with the vast majority of Unix programs. Currently, it only supports i386 and x86_64, with slowly developing ports to aarch64 and RISC-V 64. |
|||
|OSDescription=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. |

|OSDescription=The Night kernel is a 32-bit drop-in replacement for the original 16-bit kernel of the FreeDOS operating system. It uses linear memory addressing and operates in protected mode on the Intel x86 architecture. The typical user will retain compatibility with their DOS applications and gain protected mode abilities such as task switching between applications, protected memory and increased overall performance in a DOS environment. The community forum has moved from google groups to https://nightkernel.proboards.com/ |

|OSDescription=NOS is a microkernel OS project written in C++, making use of modern C++ standards (from C++11 onwards). It targets multiple architectures, is meant to be portable and provides a structured, object-oriented API. It is mostly inspired by the L4KA series of microkernels. Currently it is the basic kernel boot and thread creation / switching on x86 32-bit and 64-bit platforms |
|||
|OSDescription=The MyNOS project aims at developing a new and different operating system, based on high-level languages. MyNOS will be based on the OCaml bytecode interpreter. We'd like to explore microkernel architecture and new language definition too. |

|OSDescription=The Oberon System is an academic operating system and an integrated software environment developed by Niklaus Wirth and Jürg Gutknecht since 1980s at [http://www.oberon.ethz.ch/ ETH in Zürich]. Currently it is a single-user, multi-core, multi-tasking system that runs on bare hardware or on top of a host operating system (currently Microsoft Windows or Linux). The developers aim at producing a reliable, real-time operating system suitable for embedded systems and for industrial and in particular medical applications. Earlier it was called "Aos" (Active Object System), a nomenclature that is still in use. It is written in the Active Oberon programming language, which evolved from Oberon, a programming language in the Pascal/Modula tradition. The graphical user interface is referred to as “Bluebottle”. See also: [http://en.wikipedia.org/wiki/Oberon_(operating_system) Oberon Operating System on Wikipedia] and [http://ignorethecode.net/blog/2009/04/22/oberon/ Lukas Mathis' Blog: Ignore the Code]. Note that some stuff on these pages appear outdated, but this may be more a problem of keeping the Web-pages as current as the System. 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. Many dead links in [http://www-old.oberon.ethz.ch/native Native Oberon] reference site can be reanimated by replacing www with www-old. It has been revitalized in fall 2013 by Niklaus Wirth implementing a RISC processor in FPGA. See [http://projectoberon.com Project Oberon] |

|OSDescription=OS for x86 with the goal to provide a complex system basics implemented with a maximum delay of 1 year (virtual memory, file systems, emulation, GUI, multitasking, clean-up of general information, drivers from other OSes, USB, SATA), and general study written in NASM, C and miscellaneous language snippets gathered from the usual PC demo code repositories, books, and study of professional programs. It aims at easily building a custom OS-like DOS application manually, simple or with all the available protection and system features, to study the implementation of the different system-level tasks. It contains simple 386 malloc/free functionality for paging, simple FAT32 LBA support for displaying files and folders with a simple fopen/readdir/Read_Disk/Read_Disk_DWORD for clusters, and several functions for handling VGA, PS/2, PIT timer, ATA-ATAPI. It boots from DOS and can return to it with the exittodos command, even under the newest laptops. Contains documentation in Spanish and English. '''Decompress the TAR to the root directory. c:\start.bat launches it'''. Has miniprograms that can be invoked as commands with arguments, and has fail-proof ATA-ATAPI detection (only primary master enabled by now). '''In 2021 it will add a basic emulator for being able to call things like video modes natively derived from the BIOS and to access the memory map from the kernel.''' |

It implements some interesting, non-standard concepts, and it's deliberately not fully POSIX compliant (although the API is POSIXish as much as possible). Its goal is to handle big amounts of data (in magnitude of yotta) in an user friendly, efficient way. Has it's own built-in debugger, memory allocator, unique VFS implementation and graphical interface protocol which is somewhere between X and Wayland. Currently supports x86_64 and AArch64 architectures and is under heavy development. |

|OSDescription=One of very few operating systems that have an explicit "released to the public domain" notice. What that means is that if you spend time on this, and you later see a commercial use for it, there is absolutely no restriction on selling/modifying etc, any more than you would dig up Shakespeare and ask him if it's OK to use "Hamlet". It is designed to look like MSDOS, and the 8086 version can currently execute some MSDOS executables unchanged, the 80386 version can currently execute some Win32 executables (including gccwin - a modified GCC 3.2.3 for Windows msvcrt.dll) unchanged, and the S/3X0 version can currently execute some MVS executables unchanged (and on real IBM mainframe z/Arch hardware executes S/370 in effective AMODE 32 giving access to 4 GiB of memory), and the x64 UEFI version can execute some Win64 executables unchanged, including a completely public domain completely-self-hosting environment. It's written in C90, with some assembler. The public domain C compiler included (only) in the x64 version has a small amount of (included) C99 dependency. There is also a native ARM32 version. |

|OSDescription=The Orange OS Project started with the intent to design a lightweight Operating System. It contains a small kernel designed for those interested in the low-level, practical aspects of building an x86 system. Currently, it is designed to fit on a floppy. |

|OSDescription=QuasiOS is a x86 64-bit operating system which will be build from the ground up, currently in assembly and C, but will migrate to our own OSL (Operating System Language), when the compiler is ready. It have three main focus goals. A password capability-based system with cryptographic filesystem. A modularized kernel where the modules is hot swappable, hence updates can be made live. User friendly configuration and interaction. |
|||
|OSDescription=OS project in assembler and C. System works in 32bit Protected Mode, with multitasking and multithreading. There is also ELF attendance and dynamic linker. Quarn OS has drivers for FDC, PIT, RTC, serial port, keyboard, VGA (text mode), PCI bus and many more. It also provides tool that allow to configure it, possibilities are very wide. For example you can chose if you want it to run with full preemption, user-space preemption or without preemption. Quarn OS also has special Artificial Intelligence module that is used in scheduler, but there are plans to use it in many more ways. |
|||
Some of the work are going to be our master theses for the next year, and we expect rapid development during our theses (2020-2021). |

|OSDescription=The Sendla OS is an os targeted at having major stability, it is also targeted at running: Windows programs, Mac os programs, Linux programs, DOS programs, Beos programs, Unix Programs and many more. 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. |

|OSDescription=tachyon is another Hobby OS, longing to support x86_64 only. Currently, it boots on qemu, bochs, virtualbox and real hardware. it has not much to see, really, but a working physical and virtual memory management (still improving), kernel and user threads and some other hardware interfacing... Basic goal was to create everything from scratch with a clean code base. It uses a plugin mechanism to load different supported kernel components. |

|OSDescription=TempleOS is a 64 bit lightweight OS with multitasking and multicore support, which is ring-0-only and works in a single address space. It provides the interface for communicating with God: the user has to choose a random number from the constantly changing sequences and then it is converted to the text interpretation. Whole OS with its' software has been single-handedly created during 15 years by Terry A Davis - who also developed a programming language called Holy C together with a special compiler for it. TempleOS supports the FAT32 and RedSea filesystems (the latter created by Terry) and also the file compression. It doesn't support the networking, partially for ideological reasons, but there are forks available with added functionality |

|OSDescription=Tilck ('''Ti'''ny '''L'''inux-'''C'''ompatible '''K'''ernel) is a x86 monolithic preemptable kernel designed to be partially compatible with <code>linux-i686</code> at binary level. For the moment, it's mostly an educational project: the perfect playground for playing in kernel mode while retaining the ability to compare how the very same usermode bits run on the Linux kernel as well. In the long term, the project targets the '''embedded''' world and '''ARM''', including MMU-less systems. Currently, the project has full '''ACPI''' support and can run software like '''BusyBox''', '''VIM''', '''fbDOOM''', '''Lua''', '''TinyCC''', without any customizations. Part of the project are also an interactive '''bootloader''' (both legacy '''BIOS''' and '''UEFI''' boot) and a ''solid'' '''test infrastructure''', with extras like '''kernel coverage'''. |

|OSDescription=SyCODE Platform is (not yet but will be) a 32bit pmode OS (multitasking) with GUI. The executable format will probably the PE. I will port an assembler, a C compiler, a linker, and I will port a basic compiler (I am writing it for DOS, it will support many features ported from C language). |

|OSDescription=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. |

Latest revision as of 16:32, 25 June 2024
This page maintains a list of academic, personal, and small non-commercial operating systems. For information regarding commercial or mainstream operating systems, please visit Wikipedia.
OSes have a high mortality rate: between 2004 and 2006, 112 of 213 OS Projects disappeared from the Internet. And looking at how often these projects are started by using the OS Project Announcement forum, in that same time period 68 projects were announced! The current total is 175 projects, but just 58 of them are active (as of January 1, 2018) and only 62 have been updated at least once since 2018 (three of which have been since abandoned), and 27 since 2019. Please help keep this list current by correcting it if you see any outdated information.
OSes without an update since 2015 are now located at Abandoned Projects.
More mature hobby operating systems can also be found at Notable Projects.
Particularly advanced and successful operating systems are listed at Advanced Projects.

A
Acess2Acess2 is a kernel and operating system designed to do what Linux does, be customizable to any given situation. However, unlike Linux, it there is no need to maintain backwards compatibility with anything. It features a simple but extensible VFS that currently supports VFAT and Ext2, IPv4/IPv6 networking with TCP/UDP, USB input, and storage. Recently, this project has been moved to GitHub, but its old git repo—with outdated sources and some useful documentation—can be found here: http://git.mutabah.net/?p=acess2.git;a=summary . v0.14 outdated floppy image is available at its' old page: username - root, password is blank. Could try building a new floppy from the latest sources by yourself! (some software rot has been noticed but its fixable) |
|
AmethystThe goal, as much as there is one, is to produce an operating system vaguely similar to Windows 95/NT4 (if Windows 95 didn't inherit baggage from DOS and 3.1).. |
|
Amiga Research Operating SystemAROS aims to create a free open source AmigaOS like OS and make it better than the original. Our homepage: http://aros.sourceforge.net |

BeelzebubBeelzebub (The Lord of Flies) features a hybrid kernel, accompanied by libraries and apps written mainly in C++, serving as a platform for development and experimentation of kernel/OS/runtime features. It currently targets AMD64, with plans to support IA-32 and ARM architectures later. It aims to become a clean, modern, and efficient operating system for servers and workstations. |
|
BeeOSA simple "Unix-like" x86 kernel trying to be POSIX compliant. Currently, the project does not have any long term mighty ambition, it just want to be a good learning tool for operating systems and low level programming topics. A future "on-the-field" usage, especially when ARM port will be ready, is not excluded. |
|
BleskOSBleskOS is 32-bit operating system written from scratch in C.

BlueKernelThe BlueKernel is a simple microkernel design intended for students. It has pre-emptive multitasking with threads, message-passing and virtual memory. It is currently targeted for the IA-32 processors, but the design is strictly separated into a hardware-dependent mechanisms layer, with an independent policy layer on top of that. It has its own basic boot loader that loads the kernel and a disk driver. It also has a basic text-mode display driver and keyboard driver. As with most microkernels, the drivers run in user space and help to demonstrate message passing and interrupts. When the system starts it loads a server that allows the user to load their own processes. There are very simple example user programs to demonstrate threads, message-passing and interrupts. The website is written like a textbook to explain how it all works, focusing on the implementation rather than theory. |
|
BoneOSBoneOS is an Operating System for everyone built by everyone. The goal is to make an Operating System for 'Everyone'. Ranging from Programmers to Normal Users.

ManagarmManagarm is a 64-bit OS for x86-64. It’s written in C++ with a custom libc and a GNU like userland on top. Managarm’s main purpose is aiming for Linux compatibility while being completely asynchronous in terms of I/O. The OS is capable of running Weston and kmscon while effort is made into porting (a subset of) Xorg. Furthermore, Managarm supports many modern hardware devices, including USB 3 and has nearly full ACPI support. |
|
MaslOS 2MaslOS 2 is a goofy 64-bit OS written in C++. It has a custom stdlib, a desktop and a custom GUI-Framework. It's the follow up to the original MaslOS. The main difference being an actual scheduler and support for ELF loading/execution. It is very WIP but quite a few things work already and it boots on real hardware. Mostly done just for fun. (Not POSIX compliant or anything) |
|
MentOSMentOS (Mentoring Operating System) is an open source educational operating system. The goal of MentOS is to provide a project environment that is realistic enough to show how a real Operating System work, yet simple enough that students can understand and modify it in significant ways. There are so many operating systems, why did we write MentOS? It is true, there are a lot of education operating system, BUT how many of them follow the guideline defined by Linux? MentOS aims to have the same Linux's data structures and algorithms. It has a well-documented source code, and you can compile it on your laptop in a few seconds! |
|
MerlonMerlon is an operating system based upon my previous kernel, ATOS. It is designed to be easy to understand, and fairly lightweight (for example, it only requires 3MB of RAM to run on an x86). Currently only implemented for x86, but it should be easy to port to other platforms. Has a preemptive kernel which allows dynamic loading of kernel modules, and supports page replacements and a dynamically linked kernel-to-usermode API. Current working on implementing more of the C POSIX library. |

O
Oberon SystemThe Oberon System is an academic operating system and an integrated software environment developed by Niklaus Wirth and Jürg Gutknecht since 1980s at ETH in Zürich. Currently it is a single-user, multi-core, multi-tasking system that runs on bare hardware or on top of a host operating system (currently Microsoft Windows or Linux). The developers aim at producing a reliable, real-time operating system suitable for embedded systems and for industrial and in particular medical applications. Earlier it was called "Aos" (Active Object System), a nomenclature that is still in use. It is written in the Active Oberon programming language, which evolved from Oberon, a programming language in the Pascal/Modula tradition. The graphical user interface is referred to as “Bluebottle”. See also: Oberon Operating System on Wikipedia and Lukas Mathis' Blog: Ignore the Code. Note that some stuff on these pages appear outdated, but this may be more a problem of keeping the Web-pages as current as the System. 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. Many dead links in Native Oberon reference site can be reanimated by replacing www with www-old. It has been revitalized in fall 2013 by Niklaus Wirth implementing a RISC processor in FPGA. See Project Oberon |

OSOS for x86 with the goal to provide a complex system basics implemented with a maximum delay of 1 year (virtual memory, file systems, emulation, GUI, multitasking, clean-up of general information, drivers from other OSes, USB, SATA), and general study written in NASM, C and miscellaneous language snippets gathered from the usual PC demo code repositories, books, and study of professional programs. It aims at easily building a custom OS-like DOS application manually, simple or with all the available protection and system features, to study the implementation of the different system-level tasks. It contains simple 386 malloc/free functionality for paging, simple FAT32 LBA support for displaying files and folders with a simple fopen/readdir/Read_Disk/Read_Disk_DWORD for clusters, and several functions for handling VGA, PS/2, PIT timer, ATA-ATAPI. It boots from DOS and can return to it with the exittodos command, even under the newest laptops. Contains documentation in Spanish and English. Decompress the TAR to the root directory. c:\start.bat launches it. Has miniprograms that can be invoked as commands with arguments, and has fail-proof ATA-ATAPI detection (only primary master enabled by now). In 2021 it will add a basic emulator for being able to call things like video modes natively derived from the BIOS and to access the memory map from the kernel. |
