What is a headless CMS?

A headless CMS is a content management system that provides an API for content delivery without a built-in frontend. This means that developers can use the API to retrieve and manage content, and then use their own frontend frameworks, such as React or Vue, to present the content to users. Headless CMS allows for greater flexibility and scalability in building websites or applications, as well as the ability to deliver content to multiple channels or platforms.
