The difference is Codex couldn't shake its preference for making flashy, loud, obnoxious marketing websites that look like they're trying to sell you a SaaS. This website looks like it wants my money. Meanwhile the website from op is simple, focused, and far more comedic than codex's slew of AI-generated "jokes".

I agree, and it's on purpose. I deliberately made it stink of vibe coding. It's also hosted as a ChatGPT site.
