# Ruby client libraries

> Our Ruby SDK gives you access to the Contentful APIs and their features, specifically the Content Delivery and Management API.

Our Ruby SDK client libraries give you access to our [APIs](/developers/docs/references/api-basics) and their features.

### Content Delivery API client library

This Ruby SDK client library interacts with the Content Delivery API, a read-only API for retrieving content from Contentful. All content, both JSON and binary, is fetched from the server closest to a user's location using our global CDN.

### Content Management API client library

This Ruby SDK client library interacts with the Content Management API, and allows you to create, edit, manage, and publish content. The API also offers tools for managing editorial teams and cooperation.
