TL;DR

Sanity and Contentful are modern CMS platforms that allow teams to manage content separately from the frontend application.

Sanity offers a highly customizable content studio and flexible schema design, giving developers greater control over content structures and editorial workflows.

Contentful provides a more standardized SaaS CMS environment with ready-to-use infrastructure and tools designed for enterprise content management.

Both platforms integrate easily with modern frontend frameworks and APIs, making them suitable for headless architectures and multi-channel content delivery.
