Jamstack is often associated with a file-based content management system that uses a combination of manually edited Markdown and YAML files. That’s because many static site generators default to this type of manual content management, even today. But the reality is that some form of headless content management system has become a de facto integration in most Jamstack sites.
Jamstack.org maintains a list of headless CMSs (https://jamstack.org/headless-cms) that you can search by type and license (i.e., whether they are open or closed source). Currently, it lists 87 options. Needless to say, that’s a lot of choices and more than we can cover in a chapter. Instead, we’ll look at the different types of headless CMS available and then explore some options to give you a sense of how their approaches differ and to help you make informed choices about what you are looking for.
