Compare Cosmic.js vs. eZ Platform

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

eZ Platform is a CMS built on the Symfony Framework. It is powerful and a total rewrite of the eZ Publish system in development from 1999.

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

• A full implementation on the Symfony Full Stack Framework
• Fully featured out of the box, media library, multilingual, multisite...
• Integrated Solr powered search ensures scalability

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

• Limited number of ready made extensions
• Some bugs in the UI layer in the first version
• Learning curve for "old school" PHP developers without OOP experience
