I was thinking of building this for Next.js in a very similar way. I love the fact that this exists for a different stack! I think your implementation of the project template is definitely the way to go. As a customer, when I buy something to jump-start me, I want it to be as clean and simple as possible. Generating the project from a configuration handles that nicely.

Outside of the generator itself, what have you found most beneficial for converting customers and convincing people to buy? Documentation? Videos? The community access?
