> 25% of a decked out developer Macbook for something that sets the look and feel of an app and forestalls an entire designer hire is an unseriously low price.

Potential value bounds the price upper end, but alternatives set what the customer will actually pay. There are much more comprehensive tools of similar nature that are offered for free.

The (somewhat) unique value proposition it offers is in how it integrates into Rails, saving an hour of a developer's time — or a couple of minutes of an LLM's time, if the slot machine happens to work in your favour on that particular spin — required to manually do it themselves. That's worth something, but if you go too high it soon becomes more cost effective to just pay someone to put in that hour.
