Compare Joomla! vs. Cosmic.js

Joomla! is one of the big three PHP CMSes. Currently it uses only a single component from the Symfony project. Joomla remains a strong contender with a large number of users and extensions.

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

• Large developer and user base
• Plenty of ready made extensions available
• Tried and tested basic concepts

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

• Administration can be confusing
• Lack of focus, tries to do everything
• Codebase is a mix of old and new

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