What Is Headless Commerce?

Headless commerce is an architecture that separates the customer-facing experience (the "head" — web storefront, mobile app, kiosk, or any other surface) from the commerce engine behind it (catalog, cart, checkout, pricing, promotions), connecting the two through APIs. The storefront becomes a front-end application consuming commerce services, rather than a theme inside a monolithic platform.

Why it matters

Headless promises experience freedom — any framework, any surface, any number of heads on one engine — and independent release cycles for front end and back end. The cost is real: the buyer assembles and operates what the monolith used to include (rendering, preview, personalization, performance), and every seam between head and engine is an integration to build and monitor. For teams already paying a high integration tax, going headless adds surface area precisely where they are weakest; for teams with strong engineering and multi-surface requirements, it removes a platform ceiling.

Headless vs composable

Headless decouples the front end. Composable commerce goes further, assembling the engine itself from best-of-breed services — cart, pricing, search, PIM — behind the APIs. Every composable stack is headless; not every headless stack is composable.
