Anecdotal example, I downloaded a new alerting app recently from an indie dev who had a small following back in the day in iOS space. It asked for a subscription, like $20/year.
I thought, let me try this the (final version, from Mac App Store) app first. Well, it's a barely-there vibecoded shit. There's a bare-bones list, everything looks like my nephew designed it, the macOS "app" is a iPhone-size view of the iOS one, it has a bug that if you click on it it opens multiple duplicates of the same list view for no reason that you have to manually close, and in general it barely works.
Yay for vibe coding.
Vibe coding is mostly garbage. But it can be useful for creating instant, disposable prototypes to investigate an idea or design direction.
