Switching Cost
Sanity's lock-in is GROQ and the Content Lake. Your content exports as JSON, but any GROQ queries embedded in your frontend code need rewriting for a different query language. Teams with a few pages can migrate in a day. Teams with complex GROQ queries across hundreds of content types should budget 1-2 weeks for query translation alone. The hidden cost is losing real-time collaborative editing in Sanity Studio, which your content team may rely on daily without realizing it's not standard in other headless CMS tools.

Building Blocks
Sanity is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
