Sanity

Sanity is a platform for structured content with real-time collaboration and flexible content modeling. It provides a fully customizable editing environment called Sanity Studio, built with React, alongside GROQ, a powerful query language designed specifically for querying structured content. Content is treated as structured data rather than page-centric blobs, making it reusable across different presentation contexts.

What distinguishes Sanity from other headless CMS platforms is the degree of customization available. The Studio can be extended with custom input components, validation rules, and workflows tailored to specific editorial processes. Real-time collaboration means multiple editors can work on the same document simultaneously without conflicts. The hosted API layer delivers content globally with low latency, and portable text provides rich text as structured data rather than raw HTML, giving developers full control over rendering. Sanity is well-suited for teams that need a content backend flexible enough to support non-standard content workflows.
