Node editors aren't new, ad Comfy isn't a particularly innovative example, so this would be like asking if the Honda Civic was inspired by the Skoda Fabia because they're both cars.
To be fair, this looks extremely similar to the comfy node editor. Would be a little more like asking if the Ford Fusion and the Lincoln MKZ are related because they look a hell of a lot alike from the outside.
It doesn't look very similar to me. No more similar than Unreal Engine blueprints. ComfyUI has a better design I think but again, it's borrowing from other projects in that respect (and i don't think they would deny that)
