I think this APP is a great idea, and so far it has been implemented well.

This is a useful tool especially for the plethora of people that are struggling with Comfy UI.
The premise is quite good - do back to back test of different AI models in the same place, and create workflows that incorporate many different types of AI models in the same place to get a richer full-featured end product.

Pros:
*many novel models keep being added
*few bugs

Cons:
No free tier on anything even images?
I can't figure out the business model?
Signing up for a free account gets you $1.00 to play around with, but
I got Tier 2 and not even a dollar to get my feet wet?

Overall it's a really good product and is very productive and allows you to combine
several disparate models to get a much better end result than a majority of the solutions
currently out there.
