Sanity

Sanity is a content platform that treats content as structured data rather than pages, giving developers an API-first backend (the real-time Content Lake), a query language (GROQ), a rich-text spec (Portable Text), and a fully customizable React editor (Sanity Studio). Founded in Norway in 2016, it now positions itself as the 'Content Operating System for the AI era,' powering web, mobile, and agentic applications for teams like Nike, Puma, Figma, Cloudflare and National Geographic.
