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 Please help keep this list current by correcting it if you see any outdated information. |

* '''Ace OS''' - This OS is mainly deal with the hardware specifications. It is coded in C,C++(MingW) and Assembly(NASM). I does not want to compete with Windows or Linux. Simply it is an 32bit multitasking operating system for IA32 developed for experimental and exploration purpose. The next version (Ace 2.0) will capale of handling DLL files also. |

|||
|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 Recently, this project has been moved to GitHub, but its old git repo—with outdated sources and some useful documentation—can be found here: http://git.mutabah.net/?p=acess2.git;a=summary . v0.14 outdated floppy image is available at its' old page: username - root, password is blank.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=Aqeous is a new Completely-from-scratch, Not-a-UNIX 32 Bit pmode OS (basically a kernel right now), with SMP style Multi-Processor Support each using Multilevel Feedback Queuing Scheduling, Implementing its own FileSystem AqFS (also made a windows side AqFS Driver to communicate), Pretty good Shell, Pretty Neat VESA Graphics drivers, A Composting window GUI system with double buffering and Alpha-Blending, A primitive Scalable Font Rendering Engine and off-course mouse and keyboard drivers , Shell Scripting Support (like .bat in Windows) etc. Many things are in active development and its still not even in alpha. The Code may look pretty stupid but yeah that won't be that bad for long. The goal is to make something on which u can open facebook and send me a 'Hi' :) Currently It supports only Qemu :( But working on that too. |

* '''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. |
|||
|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. |

* '''Coronis''' - Open source RTOS written entirely in ia32 assembler language with accent made toward code size and speed optimizations. The goal of this project is to create multitasking operating system from scratch mainly for educational purposes. |
|||
|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. |

* '''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. |

|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=Kolibri 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! |

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 |

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=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 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. |

* '''OSSO''' - A Micro Kernel Operating System written from scratch |

|OSDescription=The stripped down version of FreeBSD for hobbyists and embedded systems developers. Its' primary difference is a tiny size, hence the "PicoBSD" name. Unlike OpenBSD ''(which provides the installation floppy with a limited set of features)'', PicoBSD is the only modern BSD system which could fit on a floppy - although, as the time passes and the BSD kernel grows in size - it becomes more and more difficult to fit. The archived floppies are available at https://sourceforge.net/projects/archiveos/files/p/picobsd/ |

|OSDescription=SingOS (Single Task Operating System) is a concept/pilot operating system that aims to do only one task at a time and provide all resources for that task. It is only in 16-bit real mode, with a single feature in 32-bit protected mode. The special thing is the version which is strictly using original IBM PC BIOS calls, and should be compliant with IBM PC 5150. [https://git.imada.sdu.dk/Sandsized/SingOS_Legacy_BIOS https://git.imada.sdu.dk/Sandsized/SingOS_Legacy_BIOS] This might be the only of the versions which would be active, since we have started to develop QuasiOS (which will be a full functional 64-bit OS). |

|||
|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 |

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'''. |

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. |

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)

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).. |

AqeousAqeous is a new Completely-from-scratch, Not-a-UNIX 32 Bit pmode OS (basically a kernel right now), with SMP style Multi-Processor Support each using Multilevel Feedback Queuing Scheduling, Implementing its own FileSystem AqFS (also made a windows side AqFS Driver to communicate), Pretty good Shell, Pretty Neat VESA Graphics drivers, A Composting window GUI system with double buffering and Alpha-Blending, A primitive Scalable Font Rendering Engine and off-course mouse and keyboard drivers , Shell Scripting Support (like .bat in Windows) etc. Many things are in active development and its still not even in alpha. The Code may look pretty stupid but yeah that won't be that bad for long. The goal is to make something on which u can open facebook and send me a 'Hi' :) Currently It supports only Qemu :( But working on that too. |

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. |

MichalOSMichalOS 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. |

mkfreeOSThe kernel is developed in C++. It is designed to run on Intel x86 architecture. Supported functionalities: Multitasking, Multithreading, FAT32 and BFS file systems (proper for mkfree), Virtual memory manager, Controllers, Hierarchical protection domains (Kernel runs in ring 0 and user applications in ring 3). Multitasking: Each task is executed every 1ms intervals. For now all tasks have the same priority. There is a main thread of execution and it can have these states: 1- suspended, 2- waiting and 3- executing. Multiple threads: Each task can have several threads of execution and can have several states: 1- suspended, 2- waiting and 3- executing. GUI: Simple graphical interface. |

MVS/380IBM's old IBM mainframe operating system (MVS) was public domain. With a freely available IBM hardware emulator available, this operating system was dusted off and being given a new life with some radical architecture changes. There's a similar VM/380 available too, for another IBM mainframe OS. Version 1.0 released and a group of people driving it forward on a daily basis instead of being a one-man project.

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. |

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. |

VSTaVSTa is a copylefted system, originally written by Andrew Valencia, which uses ideas from several research operating systems in its implementation. It attempts to be POSIXish except where POSIX gets in the way, and runs on a number of different PC configurations. VSTa is also designed to take advantage of SMP right out of the box.

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. |
