I actually never really got into Heroku, but I think it would be quite neat for people to use a BaaS instead of hosting the script themselves on a server since Jarvis should run at least in the background round-the-clock.

The UI is in another task request. The idea is to have the following workflow in the end:

1.) Open UI
2.) Configure Jarvis
3.) Decide between running it locally, running it on a server or running it via Heroku

Now, many people would probably be overwhelmed, so a good step-by-step guide customized for Jarvis to get started with Heroku is important.
