What is Headless Commerce?

Headless commerce is an architecture where the front-end of an online store is decoupled from the back-end commerce engine. Products, inventory, pricing, and checkout live in a system like Shopify, Medusa.js, or BigCommerce, while the storefront is built with a separate framework such as Next.js or Astro. The two communicate through APIs, so the brand controls design, speed, and content independently of the commerce platform.

Why it matters

Stock themes are fine until the brand cares about page speed, custom merchandising, or a content layer that doesn't fit the platform's idea of a product page. Headless commerce removes that ceiling. The front-end loads in milliseconds because it isn't dragging a hosted theme's bloat. Marketing edits content in a real CMS instead of bending product metafields. Design is whatever Figma says, not whatever Liquid allows. The trade is more setup. The win is a store that grows with the brand instead of throttling it. Most legacy stacks were built backwards. Headless commerce flips it.

How it works

The commerce back-end keeps doing what it's good at: storing products, calculating taxes, processing payments, managing orders. Editors update products in that admin. Content lives in a headless CMS like Sanity. The storefront — built in Next.js or Astro — fetches products and content via API at build time or on request, then renders them as fast static or hybrid pages. When a shopper adds to cart, the front-end talks to the cart API. At checkout, they either stay on the headless flow or hand off to the platform's hosted checkout. Either way, the look, feel, and speed belong to the brand.
