A Guy Vibecoded an ARM64 OS That Actually Boots on a Pi

Someone just vibecoded an entire operating system for a Raspberry Pi. It’s not a toy. It boots on real hardware.

Four Weeks and a Lot of Claude

VibeOS is a retro-style operating system for ARM64 chips. It runs in QEMU and, more impressively, on a Raspberry Pi Zero 2W. The developer, going by kaansenol5, says they built the whole thing using Claude Code in about a month. That’s the kind of timeline that would have required a small team of dedicated kernel hackers a decade ago.

The GitHub repo is full of the low-level stuff that makes your computer a computer: a bootloader, a basic kernel, a terminal, and a simple filesystem. It’s a throwback to the days when an OS felt like something you could hold in your head.

The Event Horizon, Not the Singularity

The project got some quiet attention on Hacker News. One commenter, ben_w, used it to riff on a favorite idea. He’s never liked the term “AI singularity.” In physics, a singularity usually means your model is broken. He prefers the “AI event horizon”—a point you can never seem to reach, but once you cross it, you can’t see what’s on the other side.

“Instead, I like to think of the AI ‘event horizon’, the point in the future, one that always seems like it’s ahead of you no matter how close you get, and beyond which you can no longer predict what ”

VibeOS feels like a pebble tossed toward that horizon. It’s not a world-changing OS. It’s a proof that the tools for building foundational software are now conversational.

Vibes and Rough Edges

Let’s be clear: this is a hobbyist OS. It’s a vibe, in the truest sense. You’re not going to run your web server on it. But the fact that a single person can now describe their way to a booting kernel in weeks, not years, is quietly staggering.

The real story isn’t the OS itself. It’s the process. It’s the fact that “vibecoding” is no longer just a meme for gluing APIs together. It’s a legitimate, if still quirky, method for navigating the deep end of systems programming. The event horizon might still be out there, but the water is getting a lot warmer.
