A new hobby OS from “scratch” in C# launched on March 5, 2017 with 310 votes, #58 of 3,481 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 9 years on.
In plain words
A hobby operating system built from scratch in C# and launched in 2017. The project is designed for developers and hobbyists interested in OS development and the C# language. The work is available on GitHub for those wanting to explore how an operating system can be constructed using C# rather than traditional low-level languages, making it accessible to programmers familiar with the .NET ecosystem.

- IMI made my own OS from scratch because I was bored2025 · jotalea.com.ar · ▲224
I've wanted to make my own OS since I started programming. Now, 5 years later, I did it (kind of). Sure, it is really basic, has very little functionality, but I made it and I'm proud of that. Oh, and I'm just 16 btw.

MyraOS – My 32-bit operating system in C and ASM (Hack Club project)Oct 2025 · github.com · ▲247Hi HN, I’m Dvir, a young developer. Last year, I got rejected after a job interview because I lacked some CPU knowledge. After that, I decided to deepen my understanding in the low level world and learn how things work under the hood. I decided to try and create an OS in C and ASM as a way to broaden my knowledge in this area. This took me on the most interesting ride, where I’ve learned about OS theory and low level programming on a whole new level. I’ve spent hours upon hours, blood and tears, reading different OS theory blogs, learning low level concepts, debugging, testing and working on…
My microkernel-based OS built from scratch now has basic Unix commands2024 · github.com · ▲69This 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 standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…
