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. HelenOS...

Darwin XNU is the hybrid kernel that powers Apple’s macOS, iOS, watchOS, and tvOS operating systems, forming the foundation of the Darwin open-source core. The name XNU stands for X is Not Unix, highlighting its origin as a combination of multiple kernel technologies—primarily the Mach microkernel from Carnegie Mellon University, integrated with substantial components from FreeBSD and Apple’s proprietary IOKit driver framework. This hybrid architecture merges the microkernel model’s message-passing flexibility with the monolithic performance and direct hardware control typical of Unix-like systems. ...

resea is a small, message-passing-based operating system kernel designed with microkernel principles in mind. Written in C with minimal dependencies, it emphasizes modularity, isolation, and simplicity. resea includes a basic POSIX-like interface and supports multitasking, IPC, and user-space services. It serves as both a microkernel OS experiment and a platform for learning about low-level system design without the complexity of larger operating systems.

KISS'em is an written in C, delivering something similar to object by kernel. Each kernel module could create object and one object could have many interfaces. For example filesystem could be accessed as an file (block device) or as filesystem, referencing to the same object. KISS'em will have webassembly support with support swap webassembly program memory.

This project is an attempt to design an message passing microkernel-based Operating System for the ZX Spectrum +3e computer equipped with ZXMMC mass storage device. It was made mostly for PoC purpose.
