Local development is tricky, and we have plenty of room for improvement here.
Currently we provide a special developer token [1] which will cause API endpoints to return mock responses when used locally. This way, you can use the exact same API with no difference in production & locally, so you don't have to mess with nested prefabs.
However, this doesn't help much with exposing your local machine for testing. We've toyed around with the idea of something similar ngrok built in to our Rivet CLI and integrated in to the API.
