13+ Headless CMS APIs You Can Use for Your Blog

There’s a lot of buzz around the concept of headless CMS in 2021. Technologists have been using traditional CMS or Content Management Systems for more than 20 years, but now, the world is changing. We live in an era where we consume information from different sources like smartphones, smart TV, desktop.

The main disadvantage of a traditional CMS is that it is not cross-platform; it can only be used as a web application. Using a conventional CMS, it’s challenging to create a mobile application since the servers wrap everything.

The headless CMS is a backend-only content management system using server-side technologies that make content accessible via a REST API. The term “headless” comes from the concept of removing the head (frontend) from the body (backend). Therefore, the headless CMS can be used to deliver content to multiple platforms. Below, we’ll go through some of the best headless CMS APIs.
