I've been trying to build what you're asking with https://divmagic.com

It has most of the things you said: Create your own component library, easily share through cloud, import and use them, live view and edit them online at Studio [1]

I'm also working on adding versioning and a NPM package so you can refer to your components with unique IDs and directly use them in your code.

Confused, this looks more like a tool that pulls existing HTML from other websites. Is the idea to create your component library by cloning existing components that are out there and modifying them? And then they are hosted in this cloud library of sorts?

Yes, the main idea is to clone existing components and to modify them for your own website (use-case) design. You can also create from scratch using the Studio. In both cases you can save and host the components in the cloud.
