My microkernel-based OS built from scratch now has basic Unix commands

In plain words

This is a from-scratch microkernel-based operating system with no code inherited from existing systems. It includes a pure microkernel handling multiprocessor scheduling, memory management, and interprocess communication, along with a partial C library and driver servers for keyboards, NVMe SSDs, and Unix-like file systems. Built for OS research and design exploration, the project aims to address microkernel performance limitations while developing a general-purpose Unix-like system suitable for real hardware.

Portable asynchronous microkernel with multiprocessor priority scheduling and Unix-like abstractions - lux-operating-system/kernel

In the maker’s words, at launch

This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the…

  Banan-OS, an Unix-like operating system written from scratch2024 · github.com · ▲333

  This is my operating system that I've been working for the past 2 years. All of the code is written exclusively by me except from ported software. banan-os has a monolithic kernel targeting x86 (i686) and x86_64 architectures. The project consists of bootloader, kernel and userspace libraries (libc, libGUI, libFont, ...). It also uses my custom C++ standard library partly based on stdc++. Currently I have basic TTY and GUI environment with some of the basic UNIX utilities like cp, ls and stat. I have basic support for USB (keyboard/mouse/storage), disks (NVMe, AHCI), custom…

  Anos – a hand-written ~100KiB microkernel for x86-64 and RISC-VApr 2026 · github.com · ▲115

  I pretty much always have a kernel project going on, and have been that way for decades. Over the past couple of years, that's been Anos, which has gotten further along than any of my previous hobby kernels, supporting IPC, multitasking, SMP (x86-64 only right now) and running on real hardware. LLMs (mostly Claude Code) have been used during development, but I learned early on that it's not _great_ at code at this level, so I've restricted its use to mostly documentation and tests. There's _a little_ AI code in the user space, but I have a strict "no AI code" rule in the kernel itself. I…

  My from-scratch OS kernel that runs DOOM2025 · github.com · ▲320

  Hi there! I've been on-and-off working on TacOS for a few months, which follows some UNIX-derived concepts (exec/fork, unix-style VFS, etc) and is now able to run a port of Doom, with a fairly small amount of modifications, using my from-scratch libc. The performance is actually decent compared to what I expected. Very interested to hear your thoughts. Thank you!

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
