ABOUT Cosmic

Founded in 2016, Cosmic is a headless content management system (CMS) that makes it easy for teams to collaborate to build modern content-powered products. As a headless CMS, it provide a web dashboard to create content and API tools to distribute content to any website or app.

Companies like Yum!, Big Fish, and Hypometer Technologies (among others) already trust Cosmic with their content pipelines.

In 2022, Builtwith.com shows that Cosmic was the 9th most used headless CMS on the interternet with over 300+ active websites worldwide.


Cosmic uses global content delivery network (CDN) servers to ensure fast delivery to users across the globe, except for mainland China.

There are two main reasons Cosmic CMS does not work in China.

  1. Cosmic’s CMS is not compliant with China’s laws and regulations.

  2. Cosmic does not have any servers or CDNs in China. Most websites built with Cosmic’s headless CMS, either won’t open or are extremely slow in China, as the speed test below shows.
