Sounds to me that's a bargain, for half an hour in wages I get a battle tested solution built by real humans with real human feedback in the real world, instead of some unmaintainable oneshot AI approximation with zero support. I would easily waste more than that trying to wrestle some prompt into doing what I need, and even when it finally does it's still spaghetti code that will eventually fall behind surrounding reality and lock my precious data into a custom abomination.
Clearly the value proposition here is not replacing SaaS solutions but creating very customized solutions that simply don't exist as a product - just like spreadsheets in the previous era. A spreadsheet does not pretend it is a programming language, it just solves the data processing problem the user has in a visual and intuitive way.
This is to me the most glaring issue with vibe tools, they do seemingly advanced stuff but their users don't really understand the result they get, they are just firing their harpoon and get dragged wherever the whale will take them.
