My experience with vibe coding
I’ve always had an interest in programming, because I’ve always had an interest in computers. I put together websites in HTML as a teenager (which, yes, were hosted on GeoCities) and have been occasionally dabbling in Python since.
Yet none of my projects got very far and, apart from my early websites, I never made anything useful. My efforts all followed a familiar pattern: I’d fixate on a particular resource—like an O’Reilly book or an online course—and get started with great enthusiasm, but as I’d realize I was months or years away from creating anything remotely useful, I’d give up.

That changed in late 2024 when my general frustration with WordPress, which I was using for my personal website, got the better of me. In a fit, I threw my website’s content plus a screenshot of it into Claude 3.5 Sonnet and asked the AI to replicate my site with HTML, CSS, and JavaScript. To my amazement, Claude 3.5 generated a functional website. It wasn’t perfect, but after a couple hours of working with Claude, I wound up with a website I liked even better than its WordPress predecessor.
My approach was exactly what Karpathy described. I didn’t read the code, nor did I really try to understand it (though I did have to think a bit about how the featured articles carousel works). That aside, I just told Claude what to do, copy-and-pasted the results in VSCode, saved the file, and reloaded my browser to see what changed. And it worked.

But the most important part? It was fun! Fun enough that I’ve since tried my hand at several other coding projects. I made an online tool to track initiative and roll dice when DMing tabletop roleplaying games, I made another tool to simplify rolling dice in Battletech, and I’m currently making a puzzle game for the Pico-8 virtual game console. I also used AI to guide me through setting up tools that require a bit of fussing, like OpenAI’s Whisper speech-to-text model.
Notably, all three projects were in different programming languages—HTML/JavaScript, Python, and Lua—none of which I’m even remotely proficient with. I’ve also dabbled in some C#, as I started to make the puzzle game in Unity before deciding it was overbuilt for my needs and swapping to Pico-8. I also toyed with turning my tabletop RPG tool into a Windows app before deciding that wasn’t helpful.
