Yep. It's also not self-hosted. Other than the fact that these are both CMS's with modern design on their landing pages, I don't see the correlation. They're very different types of software.
"You can host it on your laptop, or you can host it on a public server. The code is open, and so is the MIT license."
It's currently not public, so I would imagine at the moment it's all hosted on their servers, but according to their blog[0], they're going public on the 14th of October, meaning it should be self-hostable from then, one would assume.
