This is at least a little bit true for me. Examples:

https://github.com/epiccoleman/scrapio

https://github.com/epiccoleman/tuber

These are both projects which have repeatedly given me a lot of value but which have very little market mass appeal (well, tuber is pretty fuckin' cool, imho, but you could just prompt one up yourself).

I've also built a handful of tools for my current job which are similarly vibe coded.

The problem with these kinds of things from a "can I sell this app" perspective is that they're raw and unpolished. I use tuber multiple times a week but I don't really care enough about it to get it to a point where I don't have to have a joke disclaimer about not understanding the code. If one of my little generated CLIs or whatever fails, I don't mind, I still saved time. But if I wanted to charge for any of them I'd feel wrong not polishing the rough edges off.

Loved scrapio idea, gonna try it out. It sounds like a clear example of a vibe-code-tier tool, no need to get the fancy programmers bois to implement something like this, just something quick and dirty. Also a fan of the quirky text in both repos, eg. "you can just get a printout of the eleventeen exercises you're not going to do"
