​​ ​​Headless CMS is a content repository that is primarily backend based. Contents can be accessed via a provided restful API. They are known as headless due to the absence of the frontend. ​​The architecture for headless CMS has been skyrocketing in popularity and the reason isn’t far-fetched. With headless CMS, developers can build a faster and generally better digital experience all at a fraction of the cost.

This means that your contents are stored independent of your website in a connected API with a specific data structure. These APIs do the work of data delivery to channels as well as devices. ​​All these and more make the headless CMS architecture one of the most sought after for companies and brands. ​​
