This is super cool but I feel like I could just build this myself with an LLM agent, so I get worried about the value proposition for services that try to charge for this. I guess really what you're paying for is some time saving and so that you don't have to burn your own tokens to build it?
As far as I can tell, this isn’t a product, and the page has a prompt to have your own coding agent generate these. Stepshots is a bigger product that offers interactive demos, which the page contrasts with these.
