Very powerful and highly customizable headless CMS
Sanity has nailed what a headless/composable CMS should be. It gives us all the features we could imagine wanting from our content layer, without ever getting in our way. The fact that the Studio can be embedded into our own Next.js application and customized at will using React opens up a world of opportunities to use this not only as a replacement for our old CMS (WordPress) but for all kinds of other content workflows we haven't even imagined yet.

Finally a CMS that builds around you - not a CMS that you have to build around
Every CMS I've used before - Prismic, Contentful, Wordpress - requires me to structure my data in the way that their CMS wants. This can be quite limiting. Sanity comes out of the gate as a CMS as a Node package that is fully customizable end-to-end without having to deal with restructuring my data. Sanity provides an infinite product for us to fully tailor our content management experiences and focus on empowering those editors and of course, developers, to work in an incredibly convenient way.

Why Sanity is the best headless CMS
In our opinion, having built over 30 headless CMS powered websites, Sanity is much better than Contentful, Prismic and others.
Rapid schema management, image handling, ease and pleasure of editing, flexibility, scalability, pricing.
