Astria is a great service, but doesn't have ControlNet integrated to the best of my knowledge.
So, if you really want to reproduce this on your own without using a service like ours, I would advise to: i) train a model with Astria, ii) download the model checkpoint from Astria, iii) install Automatic1111 UI with the ControlNet extension and now you will have a local setup that is very close to what we have, the only missing piece is that we have a custom model optimize for faces.
