ABOUT Contentstack

Founded in 2018, Contentstack is a pioneer in API-first, headless CMS technology. It’s headless CMS specifically designed for enterprises and large scale deployments.

Contentstack helps leading companies like Mcdonalds, Chase, and Mitsubishi Electric connect with their global customers at scale.

When compared head-to-head with the popular headless CMS Contentful, Contentstack claims to beat them in every user satisfaction category measured by G2. Contentstack outperforms Contentful in key areas such as enterprise scalability, content management, and ease of partnership.

In 2022, Builtwith.com shows that Contentstack has 1,200 + active websites worldwide.


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

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