BananaOS, vibecoded operating system that boots on a 486 with ~11MB RAM

In plain words

BananaOS is an experimental operating system designed to run on minimal hardware, including 486 processors with approximately 11MB of RAM. Built primarily as a learning project in low-level systems programming, it features a custom kernel, VESA graphics with a window manager, and multiboot compliance. The OS targets i386 BIOS systems and generates bootable images through automated continuous integration. It is intended for educational exploration of how computers boot and function at the kernel level.

In the maker’s words, at launch

My 10-year-old son has been deep in low-level rabbit holes lately and ended up vibe-coding his own operating system. Since he’s still a kid and not on HN himself, I’m posting this on his behalf with his permission. This started as curiosity about how computers actually boot, and somehow escalated into writing a…

  MyraOS – My 32-bit operating system in C and ASM (Hack Club project)Oct 2025 · github.com · ▲247

  Hi 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…

  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…

  Running TempleOS in user space without virtualization2024 · github.com · ▲228

  TempleOS is an experimental OS designed to be simple and self-hosted with a JIT compiler. I was mesmerized by it but didn't like the hassle of using virtual machines to boot it up and move files around from the virtual drive. My project lets you run TempleOS as an app of some sort instead of using a virtual machine to run it - this brings a lot of benefits like speed, seamless filesystem integration (virtual machine development with stock TempleOS is really a pain.), command-line mode where you can code in HolyC on the command line instead of TempleOS' GUI. Its user-space nature lets it do…

  I 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.

  Talanoa▲346

  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…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
