Since 2009, CKEditor has served as Drupal’s default rich text editor—but in an era of headless, decoupled, and omnichannel experiences, its HTML-based approach is showing its age. ContentSync's latest blog post introduces the ProseMirror module as a forward-looking alternative that stores content as structured JSON instead of HTML, enabling seamless, adaptable content delivery across APIs and platforms.

The limitations of HTML in headless environments are well-known: rigid structures, Drupal-specific links, and embedded media that don’t translate easily across channels. ProseMirror resolves these by treating content elements—headings, links, media—as structured objects rather than visual markup. This gives developers complete control over how content is rendered, routed, and optimized for any frontend.

With an intuitive editor UI that mirrors CKEditor’s familiarity, ProseMirror minimises disruption for content creators while offering major architectural benefits for developers. The module includes built-in CKEditor-to-ProseMirror conversion, configuration flexibility, and integration with modules like Linkit and JSON:API. Though initially sponsored by ContentSync, ProseMirror is fully open source and designed for extensibility across any Drupal setup.
