What is Sanity.io?

Sanity.io is a headless CMS built for structured content management and AI-powered content operations, developed by Sanity Inc.

The CLI tool enables developers to generate TypeScript types directly from schemas, reducing friction between content structure and code.

Sanity serves e-commerce platforms, media companies, SaaS products, and enterprises managing large content volumes. Customers include Tecovas, Nike, and other brands handling complex content operations at scale.
