Compare Reservoir vs. Cosmic.js

Reservoir is a Drupal 8 distribution focused on decoupled content management. It is developed by Acquia, the company providing enterprise grade Drupal hosting and solutions.

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

• Open Source CaaS option
• Corporate backing from Acquia
• Flexibility and extensibility

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

• A young, unproven product
• Complexity of hosting (compared to pure CaaS)
• Unable to leverage full Drupal ecosystem

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