Why choose Cosmos?

Cosmos has a content editing app that is separate from the website. This “decoupled” approach has significant benefits:

  1. Flexibility and Scalability: Decoupling significantly improves performance and scalability over monolithic CMS systems like WordPress and Drupal.
  2. Futureproofing: The open architecture of Cosmos continually integrates with new technologies and platforms, guaranteeing its flexibility for future developments and breakthroughs.
  3. Enhanced Security: Separating the editor app from the website greatly minimizes hacker “attack surface”.
  4. Improved Performance: Cosmos seamlessly incorporates content delivery through CDNs and other technologies, resulting in quicker loading times and enhanced user experiences.
  5. Omnichannel Delivery: The simple Cosmos REST API easily distributes across multiple channels (websites, mobile apps, smart devices) without needing to duplicate efforts, ensuring consistency and efficiency.
  6. Easier Maintenance and Upgrades: Upgrades and patches can be deployed seamlessly within Cosmos, ensuring continuous service without any noticeable disruption to users.
  7. Customization: Decoupled CMSs offer greater customization options, allowing for more personalized and dynamic content experiences tailored to different audiences. Developers use the UI and backend frameworks of their choice.
  8. Lower cost: Cosmos is open-source software, so it is free to use. Moreover, it's cloud-native design dramatically reduces administrative overhead and delivers “big bang for the buck.”
