The long term goal is to figure out a good UX for one app config → multiple apps.
We haven’t quite decided how to route one domain to multiple apps yet, and I expect it’ll be a while before we do. But we do have a neat statics feature you can use for backend/static app deployment. It should be pretty easy to build statics into an API image, and you wouldn’t need to add any other webservers (since we handle that).
