Headless and composable are hot topics in digital, but what exactly do they mean?
In the simplest terms, headless is a system with a decoupled back-end and front-end. Composable, on the other hand, is a comprehensive approach to consolidating headless initiatives—ultimately bringing agility to the digital experience (DX) infrastructure. Think of composable as the big sister of headless digital experience architecture.
Let's take a closer look.
What Is Headless?
Headless, or decoupled, refers to any system where the front-end and the back-end are connected by an Application Interface (API). It is a pretty broad definition that can be applied to a lot of solutions, like Ajax, web apps, PWAs, IoT, or native apps.
Headless makes sense; it is a great way to deliver snappy user experiences by reducing the amount of redundant data being sent during an experience. By separating content and presentation layers into separate back-end and front-end systems, headless architecture lends itself to high-performing applications—but it doesn’t inherently address business agility. That is where composable becomes interesting.
