"Ehh I don't really do that kind of software..."
If I was to give this guy a simple marketing site, that he can take to go host on his own, that I can hopefully vibe-code into existence, what should I use?
I mean, I know how to do this stuff, but handing him a node package seems wrong.
Anything you code, manually or vibe-ly, is going to become a pile of unmaintainable garbage in a year or two and either you're going to have to help him fix it then or he's going to have to pay hundreds for someone else to do it for him (if he can find anyone).
Please believe me when I say I've wasted way too many years of my youth trying to hack together things like that for clients. That way lies madness. Don't let yourself go down that path. It's not a good use of time and money for you or your client.
These are trivial for us but for him would be a great starter and timesaver.
