Gatsby, when used with Drupal as a headless CMS, offers a robust and modern development experience by combining Drupal's enterprise-level content management capabilities with Gatsby's powerful UI creation and performance tools. This setup, known as decoupled Drupal, is increasingly popular for building enterprise-grade websites, supported by Drupal community leaders. The integration is simple, requiring the addition of the gatsby-source-drupal plugin and access to Drupal data via GraphQL queries. Drupal is particularly well-suited for projects involving complex page layouts, multi-stage content creation processes, and teams that prefer open-source technologies, although it may not be ideal for those needing a slick content editing interface. Using Gatsby and Drupal together provides a free, open-source alternative to expensive enterprise content management systems, enhancing performance, scalability, and security typical of the JAMstack architecture.
