Contentstack

With the help of a JSON architecture and APIs supported by content delivery networks (CDNs), Contentstack is a headless CMS software that enables businesses to deliver personalized content experiences to audiences via various channels, such as mobile or web devices, augmented or virtual reality platforms, and the Internet of Things (IoT).

Administrators can set up role-based access permissions for adding, amending, publishing, or deleting content entries as well as modify or format photos for a particular device's display.

To offer individualized, multichannel digital experiences, Contentstack brings together business and technology teams from Enterprise, SMB, and Startup organizations
