Gatsby isn't a CMS in the WP or Drupal sense of the word. Gatsby to me is more of an "integration first" minded architecture. That is, Gatsby is a way to unite multiple services, CMS's and content sources. But other than using .MD files Gatsby doesn't really have the ability to manage content in a true CMS sense. It's not like you log into some Gatsby admin panel and add content.
