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 Please help keep this list current by correcting it if you see any outdated information.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 182 projects (as of 10:21, 7th December 2009 (GMT+12)). 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 Recently, this project has been moved to GitHub, but its old git repo—with outdated sources and some useful documentation—can be found here: http://git.mutabah.net/?p=acess2.git;a=summary . v0.14 outdated floppy image is available at its' old page: username - root, password is blank.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=AtlantisOS is designed from the ground up to include the most efficient mechanisms and modern techniques to construct and maintain the operating system. Notable differences with current other operating system projects is that the code is released into the public domain, drivers are only made when the base layers are fully in place and nothing is made with the base layer half implemented or only stubbed. This also explains the lack of progress, although it can boot up and detect a number of PCI devices by now. Releases are not often, but the code on SVN is usually stable and more capable than the last release. |

|OSDescription=A 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. |
|||
|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=BleskOS is 32-bit operating system written from scratch in C. One of main features is alternative graphic user interface that do not use windows, as classic operating systems do, but switches between programs on full screen. BleskOS is designed for older computers. Goal of BleskOS is to provide system, that could be installed on older computers to make them usable again. BleskOS have wide range of drivers such as VBE, AC97, Intel HD Audio, PS/2 keyboard, PS/2 mouse, PATA(PI), SATA(PI), USB controllers UHCI/OHCI/EHCI, FAT filesystems, ethernet cards from Realtek, Intel, AMD and more. BleskOS also supports widely used file formats like JPG, PNG, GIF, MP3, TXT, HTML and more. Every version is tested on multiple real computers. |

|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=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. Caracal has just undergone a redesign, where the boot loader has been made much more versatile and the kernel now uses a separate arch tree to enable easier porting. Currently, the i586 and x86_64 versions of the kernel are under initial development. |URL=http://www.ajsoft.co.uk/ |

|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=Fiwix is an '''operating system kernel''' written from scratch, based on the UNIX architecture and fully focused on being POSIX compatible. It is designed and developed mainly as a hobby OS and, since it serves also for educational purposes, the kernel code is kept as simple as possible for the benefit of students and OS enthusiasts. It is small in size (less than 50K lines of code), runs on the i386 hardware platform and is compatible with a good base of existing GNU applications. A special floppy image with RAMdisk support is available. |

|OSDescription=JSD/OS which either stands for "Jake S. Del Mastro Operating System" or "Jake'S Disk Operating System" is a tiny Pseudo Single-Tasking operating system for 32bit x86, developed on and off since 2014. The goal is to build an OS with a very small memory footprint, a fast file system and minimal overhead to allow user requests to be processed as quickly as possible, ideal for interactive applications, using a unique scheduler known as CuFS (Conciously unFair Scheduling). The system can run applications packaged in the ELF object format and has full support for memory protection via virtual address spaces. The system includes a shell which works with many DOS & Unix commands. |

|OSName=JSLK |

|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.

Despite fitting on a standard 1.44 MB floppy, this wonderful OS contains: the complete GUI desktop, a lot of drivers and great software (such as web browser and music player), system programs and games! The Kernel and most applications, libraries and drivers are written in FASM, but some are in C-- (https://en.wikipedia.org/wiki/C-- ; link to their C-- compiler: http://c--sphinx.narod.ru/). At this OS you can write the ASM code and execute it after assembling. Source code is open - http://websvn.kolibrios.org/listing.php?repname=Kolibri+OS - and the contributions are welcome! |

|OSDescription=MichalOS is a new x86 hobby OS project that is based on MikeOS: it has been created during the time when it seemed that MikeOS is abandoned, and has more features/programs compared to the original project. Also, these two projects seem to have a different focus: MikeOS appears better suited for education (i.e. has more documentation) while MichalOS is more about running/creating the cool stuff: has more games, a music player with nice "retro computing"-style music, etc. |

|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.''' |

|OSName=OS/Z |
||
|OSDescription=OS/Z is an open-source, multiplatform, micro-kernel hobby OS written in C and assembly. 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=OS/C is my small, open-source, Unix-like OS. It is (and was) designed to preform networking tasks and other file-oriented processes whiltaking up very little of the computer's processing power. |

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=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). |

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. |

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=A small project to port the .NET runtime onto bare metal, and run managed kernel on top. |

|OSDescription=U365 is a monolithic 32-bit OS in its alpha stage. It includes VFS, STDIO, keyboard and mouse drivers, VESA modes and some simple screen surface management. We used C and Assembly to code it. |
|||
|OSDescription=The Useless OS is made entirely in ASM compiled with NASM. It is currently a 16 bit Real-Mode OS with a FAT12 filesystem. It has around 30 system calls and an ASM header for developing applications for the UOS. Applications can be developed in ASM, or with a BASIC compiler called UBASIC (Useless BASIC) that was programmed in FreeBASIC. The UBASIC Compiler takes BASIC code and translates it to NASM code which in turn compiles it to flat-binary or .COM applications. The way the UOS multi-tasks is more like task switching in real-mode. A GUI is currently being developed. Future plans are to write a 32 bit p-mode extender, then port the GUI to use it for better multi-tasking. Note that our website is under construction. |

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.

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) |
Open source; inside the source code archive there are broken symlinks /Kernel/arch/x86_64/rme.c and /Kernel/arch/x86_64/rme.h to Real Mode Emulator files which are available here - https://github.com/thepowersgang/rme2 http://www.mutabah.net/acess2/ Last commit: 2016-06-22, currently abandoned - the author has switched to his other project, Rust OS (https://github.com/thepowersgang/rust_os)

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. |

JSLKJSLK 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.

Kolibri OSKolibri OS was a fork of the 32-bit version of Menuet OS but has changed much along the way. Despite fitting on a standard 1.44 MB floppy, this wonderful OS contains: the complete GUI desktop, a lot of drivers and great software (such as web browser and music player), system programs and games! The Kernel and most applications, libraries and drivers are written in FASM, but some are in C-- (https://en.wikipedia.org/wiki/C-- ; link to their C-- compiler: http://c--sphinx.narod.ru/). At this OS you can write the ASM code and execute it after assembling. Source code is open - http://websvn.kolibrios.org/listing.php?repname=Kolibri+OS - and the contributions are welcome! |

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.

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. |

TempleOSTempleOS 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 |

xOSxOS is a hobbyist operating system project written mostly from scratch for the PC, entirely in FASM-style assembly. The principal goal of xOS is to be compact and lightweight, yet be suitable for use in the 21st century, in terms of speed, features and hardware support. As such, xOS supports IDE and SATA hard disks, partial support for USB, networking, a rudimentary web browser, and a compositing graphical user interface. The kernel and drivers have been written entirely in assembly, while applications can be written in C. |
