Testing, testing, is this thing on?
This post marks my successful deployment of Sanity CMS on this website. Sanity is a headless CMS.
I've used headless CMSs in the past (Netlify and Dato), but Sanity is a whole other thing. The documentation is thorough, the features are robust, and that means setting up Sanity is no click-three-times-and-you're-done task.
It's a full-featured headless CMS, and I recommend it for full-time developers or publications with a dedicated development team.
