A headless CMS editor should be evaluated by the content model people actually author. In Sanity Studio, define one document with relationships, images, validation, and a preview before comparing it with alternatives.

Ask an editor to create, revise, and publish it, then restrict a second user to the intended fields or dataset. Check how schema changes affect existing documents and how the front end handles missing fields. The Sanity schema guide explains that schemas shape Studio forms while content resides in Content Lake.

Export a representative sample and verify portability, media, and references. Compare collaboration, roles, API usage, and the maintenance of custom Studio code. The right choice gives editors guardrails and developers a stable contract, not merely a flexible blank canvas.
