Contentful

One of the most popular and simple Headless CMS. It runs as a web service, so you have only to register an account to create a project. Contentful is very easy to use, stable and has a free version. In addition, there are lots of plugins and a package for working with this CMS.

But there are some shortcomings. First of all, it's a limitation of entities (models) and fields in the model. Also, like many Headless CMS services, the size of uploaded files is limited.

Despite the great popularity of Contentful, it could be a challenge to create even a small project due to limitations. Therefore, we recommend using it only for very simple projects.
