Slightly tangential: a lot of my vibe coding experiments are standalone SPAs because I can't be bothered to set up a secure server (and I am too cheap to pay for it). I love that I can open my "mobile-first" apps directly from my phone's Downloads folder.

I have a feeling that a lot of these little tools people make with low-code vibe AI apps do not require more than a single HTML page with JS imports.

(I also suspect that there is a ton of duplication in what people create, but, of course, I have no data to back it up.)
