The Logos Press Engine is a in-house created website that is hosted at https://press.logos.co
The Github repo that hosts that codebase can be found at https://github.com/acid-info/logos-press-engine
It was created to be the hub that aggregates all content creation and funnels people to regardless of how it’s distributed. As I understand it, due to various strategy and CC changes, it isn’t leveraged or updated as much these days.
The content is managed through a self-hosted instantiation of Strapi, see that page for details on how to use it.
