Sorry to write this comment: isn't it exactly like ComfyUI?
I would say that although the form factors look similar, we are operating at a different abstraction level. ComfyUI focuses on components within the HuggingFace diffusers ecosystems and allow artist to recompose different workflow to come up with amazing visual effects.
We're trying to offer a way for people to recompose apps/apis with foundation models!
This supports other models.
That being said, you're not wrong. It's definitely inspired by ComfyUI. But, with much simpler abstractions, much broader utility and extensions like building a user front end coming up shortly
