What is Bubble?

It answers the first part of my question, yes…thank you!

So when I’m building out workflows in the Bubble editor, Bubble is actually “combining hand-coded javascript modules seamlessly into a working node.js application”.

Would I be able to export that “working node.js application” and go run it on a Node server somewhere else (say Digital Ocean or Heroku)? Can the node.js application that Bubble creates run independently of the Bubble hosting infrastructure?
