OK, but really: What is a headless CMS?

So what does that actually mean? Why is headless architecture important to the future of digital experiences?

Headless architecture is partly a response to the way web content has evolved. For a long time, most web content was delivered through a browser, often as a web page. But new connected devices are arriving all the time.

Today, audiences consume content through new interfaces with different form factors—things like smartphones, wearables, AI-enabled voice assistants, and even virtual reality headsets.
