Looking for Information, Documentation, and Roadmap on Webflow Architecture

Regarding the wishlist: There is an update and some kind of roadmap for 2021.

To your questions:

  1. I think it is not possible to enhance the CMS since Webflow is a low-code platform. If you need features, the Wishlist is your best bet (but prepare to wait years at the moment). Maybe there will be a plugin system in the future …

  2. and 3. There is an API, but I don‘t know if it fits your needs. Also, you can add custom code in the designer to do all kind of JavaScript stuff.

  1. This question is better answered by staff, but with the API it should be possible to run Webflow in some kind of headless fashion.

And to my knowledge, Webflow uses AWS under the hood and scales automatically.
