Sanity Studio
Sanity Studio is a real-time collaborative application for content creation. It's open-source and connects to the hosted Content Lake.
You can quickly get up and running and define your schema types (content models) with plain-old JavaScript objects. From your definitions, Sanity Studio will autogenerate an editing environment that comes with a ton of features out of the box (document versioning, real-time collaboration, nested and connected content, conditional fields, initial form values, etc).
Sanity Studio also comes with a framework for customizing editing experiences that lets you do everything from defining custom form validation with JavaScript to building input components with React, and much more.
