What's Magnolia headless CMS

Magnolia CMS is a content management system that works on top of JCR. It is so feature rich that you can use it completely decoupled from UI headless way. So that you have the freedom to use your own front end like react, vue or angular. Exciting part of this concept is that, while front end is developed in your favourite framework, the admin panel enables frag and drop page building from inside CMS. So an editor/ marketer can see what they're publishing for the end users.
