Sanity is a headless CMS built around a principle it calls “structured content” — the idea that content should be modeled as data first, with presentation a separate concern. For publishers whose content is genuinely complex — articles with rich metadata, multiple content types with relationships, content repurposed across channels — Sanity’s approach delivers a level of flexibility that database-backed traditional CMSes struggle to match. It is not the simplest tool in the category, but for the use cases it is designed for, it is among the most capable.
