Top 10 operating-system-kernel open source projects

A toy monolithic kernel written in C++

My ongoing experimentation on operating system internals, aiming at providing a kernel to the FreeDOS-32 project.

A kernel written in Rust

Apex RTOS - A (somewhat) Linux compatible real time operating system

Operating System Coded in Assembly and C

A new operating system kernel with Linux binary compatibility written in Rust.

Our very own Operating System built from scratch for x86 architecture systems!

Open Source Rust kernel; Runs WASM and WASI as lightweight containers.

MoonOS (just a kernel atm) is a micro kernel designed for the x86_64 and arm architecure.

Non-unix, custom-API hybrid OS kernel written in C++ which can be thought of as an emulated microkernel. The native API is almost fully asynchronous and the kernel is aimed at high-scaling, high-throughput-requiring multiprocessor workloads, with working support for SMP and NUMA already implemented.
