Compare Drupal 8 vs. Cosmic.js

Drupal 8 is a partial modernisation of the legacy Drupal CMS with a few parts of Symfony under the hood. Usability improvements were not the focus and to the end user Drupal 8 is very much like Drupal 7.

Cosmic.js is a CaaS based on GraphQL. It follows on the footsteps of both Contentful and GraphCMS.

• Based on stable legacy with critical APIs in place
• A large number of ready made modules (for Drupal 7)
• Large mass of developers brings stability for purchasers

• Excellent usability for editors
• Developer ergonomics
• Clear pricing model (no free tier, though)

• A custom architecture based on Symfony Components, proprietary module structure
• Usability of admin interface not very good and remains tightly coupled to Drupal
• Suspect to security issues due to custom implementation and popularity (see Drupalgeddon)

• Limited content modeling capability
• Lack of customisation options
• Vendor lock in
