The app builder part of our project is open-sourced and makes it easy to put a user-friendly UI on top of any ComfyUI workflows: https://github.com/ViewComfy/ViewComfy
The cloud services include an auto-installer that takes care of all the nodes and models needed to run a workflow, so that you can get started quickly. It can be used to deploy ViewComfy apps or APIs.
We've created a playground section where you can see some examples of workflows that we have deployed already: https://playground.viewcomfy.com/
