If I were a bit more bloody-minded I would launch a service for vibe-coded apps that, under the hood, did everything "the right way" and just charged a flat fee + percent on the underlying.
I feel like if this was done correctly it would eat a bunch of the market, but I question how many people are actually willing to pay for "the right way". The last time I had that experience it was with Heroku which was quite a leaky abstraction.
I think a lot of people have built those services. But doing it right is more expensive, and people end up choosing the $5-$10/mo option over your $30/mo+ that does it right. Multiply those numbers by whatever multiple you want for higher end stuff.
And the LLM say: "You're absolutely right! We didn't need jaggederest's service. We can build it easily."
