Hosted Backend: A secure, optimized and fully managed data store:

• The data can be accessed either by using one of the client libraries or directly via HTTP.
• The content is stored and transmitted as JSON documents.
• The documents are optionally subject to a specified JavaScript schema.
• The data is encrypted at rest and in transit and APIs are TLS / SSL only.
• The performance is enhanced with load-balancing, caching and a Global CDN.
• The Graph Oriented Query Language can be used to retrieve the exact fields you need from the backend, joining together information from several sets of documents if necessary.
• Your Frontends and tools can be notified whenever content is changed either using realtime listeners or via webhooks where the changes are submitted as HTTP requests to a custom URL.

Content Studio: An open source, customizable and real-time content editing environment:

• To use Content Studio, it must first be built using the command line before launching it locally. It can then be deployed to a service hosted by Sanity.
• To edit your content, a Rich Text Editor is provided based on the Portable Text specification.
• Validation rules can be defined on your document types and fields.

Assets can be stored, transformed and deleted either via an UI, or using an API. Images can optionally be resized, cropped and processed by the image pipeline.

A Command Line Interface that makes it easy to create new projects and set up, import and tear down datasets.
