Ask HN: Any Recommendations for a Headless CMS?

I've been using Cockpit (https://getcockpit.com/) for a few internal and personal projects now.

It's lightweight and easy to use. Just upload the folder to your webspace (minimal PHP requirements!) and you are good to go.

Create some collections for you data, link them if needed, and you can immediately use them via the API endpoints AND also via a GUI for CRUD operations.

This is really great because my colleagues are non-technical and I don't need to write some frontend for them to update data and so on and can concentrate on the "real task".

Documentation on the other hand is awful, to the point where you better refer to the "inofficial documentation" (for the interested: https://zeraton.gitlab.io/cockpit-docs/) with no way to improve the official one.

So, while I LOVE the ease of use, I wondered if somebody has a recommendation for a similar solution which might be somewhat more "mature" in regards to the documentation.
