This is appealing to me as a Python backend dev-- but if I end up building something cool for my own personal use, and I want to deploy it so others can use it-- is that a thing for this? I don't see any kind of documentation for deploying it, but that could just be on me. I realize this is touted as a demo-friendly / internal tool so that just might not be aligned for this type of thing.
Yeah, you can definitely deploy it to share with others. Check out our deployment guide (https://google.github.io/mesop/guides/deployment/) which shows you how to deploy Mesop apps to Google Cloud Run, but you should be able to deploy it on pretty much any service that takes a container.
