Decoupled Days is a conference for architects, developers, and businesspeople involved in implementing headless CMS architectures. The 2023 edition is scheduled for August 2023 in Albuquerque, New Mexico.

Headless or decoupled CMS is the use of a content management system as a content service for other non-CMS applications, whether they are in native desktop or mobile, universal JavaScript, set-top boxes, IoT devices, conversational interfaces, or other technologies.
