A comparison of operating systems written in Rust.

There are several open source operating systems written in Rust. Most of them are proofs of concepts. The only system that goes a step further is redox. It comes with a window manager as well as basic applications like an editor and a file manager.

    Add discussion of Theseus OS

    Hi @flosse,

    Thanks for maintaining this neat list of Rust-based OS projects!

    I'd like to add one more: Theseus OS. Theseus is a somewhat large OS written from scratch in pure Rust, thanks to collaborative efforts from 20+ contributors over the past several years. I have added links to it and a brief description of its key aspects in the comparison table of systems.

  • add SOS

    add SOS

    I've taken the liberty of adding my own toy kernel project, SOS.

    While SOS is still very much a work in progress, I think it's noteworthy enough to add to the list, because as far as I know, it's the first working x86_64 kernel implemented in pure Rust. As of hawkw/sos-kernel@f436b2dc25bfa5aba11c6dbffcbd5e058e9cfafd, SOS boots to long mode without a single assembly file in the repo (with a little help from multiboot).

    I hope it's not too presumptuous of me to add my own work to the list. Thanks!

  • Add MOROS

    Add MOROS

    Hi, I'd like to add MOROS to the list!

    It's a hobby OS I've been working on and off for the past 2 years, it's inspired by Unix but it definitely won't be big and professional! The goal is to have a clean and simple text environment to have fun with computers from the 2005 to 2020 era.

    Currently there's a limited userspace capable of running simple nasm programs (one at a time!) with some syscalls, but most programs (a shell, an editor, a lisp, a chess game, a 2048 game...) are running from kernelspace. It also has it's own simple filesystem and a network stack.

    Hi,

    I'd just like to draw attention to Tupai, the kernel and userland I've started working on. It's still in an early stage of development, but I have big plans for the project. Check out https://www.github.com/tupai-os/

    redox x86?

    redox is marked as x86 and x86_64, although it seems the redox kernel only has an x86_64 linker script, it also has an arm target file here. No mention anywhere of x86 though

    Why is Intermezzos marked as not being pure Rust?

    I am just wondering why intermezzOS has been flagged as not being a pure Rust implementation? The repository contains nothing but Rust code and Assembly (It also shows Ruby from a vagrant file). If there is something I am missing I would love to know! Thanks for your help!
