My "favourite" CMS is TakeShape. It's a general purpose headless GraphQL CMS and static site generator. I'm a little biased because I'm one of the Co-founders of TakeShape. But we've worked hard to try to strike a balance between developer UX and content producer UX to build something that helps everyone be more creative.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
