"wow, this headless looks pretty cool"

"The codebase is written primarily in PHP"

Ah, yes.
So, what is you r favourite headless CMS out there?

I have several questions...
- how can a headless service "look", there is no front-end bound to it.
- Is it wrong to be written in PHP?

CraftCMS, natively built-in GraphQL headless mode, sane API, intuitive back-end, 1-2 updates per week.❤️

Looks metaphorically, as in the concepts behind it are pretty solid.

And thank you, I will certainly take a look at it!
