Open Source ChromeOS Operating System Kernels

Community driven projects featuring the latest innovations for cutting edge apps. Our flagship project JBoss AS is the leading Open Source, standards-compliant, Java EE based application server implemented in 100% Pure Java.

Memory OS is a local memory operating system for Hermes Agent. It is designed to help an AI agent retain project context, decisions, structured facts, reasoning patterns, and prior conversations across sessions. The system uses seven memory layers that combine flat files, SQLite, full-text search, structured facts, semantic recall, Qdrant vector storage, and a self-curating wiki pipeline. It injects only relevant context back into the agent so memory remains useful without wasting tokens. The project is provider-agnostic and can work with services such as OpenRouter, OpenAI, Anthropic, Ollama, or local models. It is useful for power users who want a self-hosted, long-term memory layer for AI coding and research workflows.

Cooperative Linux is the first method for optimally running Linux on Windows and other operating systems natively. It is a port of the Linux kernel and support code that allows it to run cooperatively without emulation along with another operating system.

This project reimplements from scratch the RPL language made popular by HP programmable calculators, in portable C/C++. The main goal is to release a complete computing environment for various targets. There's currently 4 active targets: the HP 50g, HP39gs and HP40gs calculators and a PC simulator (see the downloads section!). Other ports are planned for the future.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

Moss Kernel is an open-source operating system kernel project designed to explore modern OS design and provide a foundation for experimental system research and development. Rather than replicating traditional monolithic kernels exactly, it emphasizes modularity, safety, and simplicity by incorporating well-structured subsystems for memory management, scheduling, and device abstraction that are easy for contributors to understand and extend. The kernel uses Rust as its primary implementation language, which gives it strong memory safety guarantees and helps reduce common classes of bugs like data races and buffer overflows without sacrificing performance. It aims to serve as both a learning tool for systems programming students and a testbed for advanced research in kernel architecture, enabling experimentation with new ideas in process isolation, resource management, and driver models.

Committed to the development of fundamental ACPI (Advanced Configuration and Power Interface) components for Linux. This includes a generic ACPI table parser, AML interpreter, bus and device drivers, policy, user interface, and support tools.

Gobudgie is using the powerfull Budgie desktop combined with the Ubuntu base. The user interface is designed for Android users so we're using a material theme. Gobudgie offers several ways to easily access or install applications. We integrated the Chromium OS Web Store the standard Ubuntu Software Center, an Android App runtime, PlayOnLinux and Wine.

This is a small library that allows comunicating with a Webasto (tm) W-Bus capable car heating system. Runs on Personal Computers or for embedded devices (slim design). Easily portable. Includes a Heater manager, heater controller program and more. The GIT repository (CVS is deprecated) also includes a control unit application to control W-Bus capable devices, a W-Bus compatible heater unit firmware application and a heater simulator for testing purposes. Also, a serial port loop back driver for linux is included to simulate OBD II K-Line adapters.

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

chaos is a new operating system - written from scratch by a young group of people. Unlike most other systems, we do not try to reimplement something else, but rather tries to do things in our own (hopefully better) way.

UFFS: Ultra-low-cost Flash File System, designed for NAND flash working in embedded system. UFFS typically consumes less then 200K ram for 1Gb(page 512)/4Gb(page 2K) NAND flash. It supports direct flash interface, works with or without OS.

Provide secure and stable OS, based on highly modified Linux Kernel, own package system, like "BSD Ports". Compatible with x86, Power PC. Easy to use of any level users. Complete Documentantion in many languages. 99% compatible with Windows.

A simple operating system made for educational purposes. It will be a 32 bit multitasking open source operating system. Latest release covers interrupt handling, device drivers and shell service.

Library for filesystems intended to be used in embedded projects. The library currently supports FAT12/16/32 reading & writing on SD-cards, and is easily expandable for use with other devices on any platform.

Infinity OS is going to be a fully featured, multithreaded, open-source operating system for the x86 architecture. It will utilize persistent objects and incorporate many features of other operating systems. We also aim for Win32 and UNIX compatibility.

Sets out to be an innovative new operating system while retaining compatibility with POSIX and Win32

Open OS aims to be a Linux-based operating system with true and complete Win16 and Win32 compatibility as well as enhanced features. OpenOS will rely on the XWindows server, but will use its own desktop environment and window manager.

SuperWaba is a Virtual Machine for handhelds. Runs in PalmOS, Windows CE, Win32, and is fully emulated under JDK/browser. Supports Exceptions, has a complete set of UI controls (Palm/WinCE), double and long, grayscale/color, sockets/serial/IR/Bluetooth

TinyOS is an operating system for embedded sensors and networks. Versions 2.0 and later of TinyOS should be downloaded from www.tinyos.net.
