Should I use a CMS, Headless CMS, building it myself with a framework like React and libraries for authentication/etc...? Big points would be ease-of-use, time-efficiency, but also customizability. Basically I'd love to code the frontend from scratch and just have a backend do the login service for me, which is what I believe a headless cms does, but I'm curious on what your guys' workflow is and what you think is best!
