os-tutorial is an open source educational project by cfenollosa that teaches the basics of building an operating system from scratch. The repository provides step-by-step lessons starting with bootloaders and moving through kernel development, interrupts, memory management, and system calls. Each tutorial is accompanied by clear explanations, code examples, and references to deepen understanding. The project uses x86 assembly and C to illustrate concepts, making it accessible to students and hobbyists interested in low-level programming. ...

operating_system_guide is a curated, beginner-friendly resource aimed at helping aspiring developers learn how to create an operating system from scratch. Maintained by AzkaDev, the guide collects educational materials, links, and code snippets that walk learners through each major component of OS development—from bootloaders to kernel structures and system calls. While still evolving, the guide acts as a roadmap and inspiration hub for those wanting to explore low-level systems programming with a hands-on approach.

HelenOS is a portable microkernel-based multiserver operating system written from scratch. It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand. ...

This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the Linux kernel. ...

...All the included software is free and open-source software made available both as compiled binaries and in source code form, which allows modifications to the original software. FiwixOS 3 uses the Newlib v3.1.0 as its C standard library, and the Ext2 as its primary file system. 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 40,000 lines of code), runs on the i386 hardware platform and is compatible with a good base of existing GNU applications.

TempleOS is a 64-bit kernel with compiler, graphics library and tools. It is not a Unix. It was made from scratch.

Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. Although the Blackfin architecture has been in the mainline kernel since 2.6.22 (May 2007), there are various fixes and patches applied locally that are not upstream. Please use the kernel from here - and treat it like any other distribution kernel. ...

3plex written in 500 minutes in Assembly! Game was written especially for ABBUC SW contest 2015 1st compo version of this game took only 500minutes to code from total scratch! Additional features were added later.

Clicker is a project for a Multitasking Open-source operating system written from scratch. based on a modular micro kernel. We want to explore new way of designing and using OSes :) [newz: PCI, NE2K and VBE]

Ace is a micro kernel for developers and researchers. The main goal is to create a very light and compact kernel from scratch with modern OS research concepts.

An operating system kernel designed with simplicity, readability, and elegance in mind. No longer written from scratch, but built on "the shoulder of giants." Specifics are given in the CREDITS file starting from v0.04

An Operating System designed and developed from scratch in C/C++ for x86 alike platform. Aim is to build a minimal complete packaged OS with support for USB, Internet (wifi) and a cool GUI, and make it suitable for tablet pcs/netbooks/smartphones

LoseThos, a free, 64-bit, multicore, PC operating system designed from scratch -- not a Unix. No bloat. Boots in 2 seconds. Comes with games, C compiler, tools and lots of demos of the API! Test-drive or install -- it is a live CD.

COS is an Open Source Operating System, which is currently in development. It is made from scratch, except it uses GRUB as a boot loader. Comments would be kindly taken, and all criticism is accepted.

Crocos is a small opensource UNIX-like kernel, designed with simplicity in mind, for educational purposes. It is developed in several steps to allow people to understand how a tiny operating system can be built from scratch.

libposix is a bold attempt to unify the impementation of the core functionality of all Unix systems. libposix is a full, cross platform, implementation of the POSIX 2008 standard written from scratch.

rmapc is an efficient free map compiler for games using BSP files. Although influenced by id Software's quake map compiler, rmapc is developed from scratch and does not reuse code with similar utilities.

Minirighi is a multi-threading open-source operating system written for didactic purpose. It has been written from scratch and it is compatible with POSIX.
