What’s Headless Commerce?
The short answer
Headless commerce splits the storefront (what shoppers see) from the commerce engine (cart, checkout, catalog). The storefront becomes a custom Next.js or Astro frontend; the commerce engine is still WooCommerce, BigCommerce, or Shopify under the hood, accessed via API.
№ 01The longer answer
Traditional ecommerce stacks bundle the storefront and the commerce engine in one platform. WooCommerce renders both the product page HTML and runs the cart logic. Shopify does the same. Headless decouples them: the frontend is a separate Next.js (or Astro, Nuxt, SvelteKit) app deployed to Vercel or Netlify, and it talks to the commerce engine over GraphQL or REST.
What you gain: blazing performance (LCP often under 1.2s), full frontend customization (any UI pattern you can build in React), edge caching of product pages globally, ability to reuse the same commerce engine across web/mobile/kiosk/B2B portal. What you lose: every plugin’s frontend (you re-implement it), checkout customization complexity (you build vs configure), the ability for non-developers to edit pages without Storyblok/Sanity investment.
The cost: 2-4x more to build than monolithic, 30-50% more to maintain. The threshold where the math works: typically $10M+ GMV, or aggressive frontend differentiation (configurators, 3D product views, immersive content). Below that, monolithic WooCommerce on Kinsta with proper caching delivers 80% of the performance benefit at 30-40% of the cost.
We build headless WooCommerce when the math justifies it — usually for clients with strong dev teams who’ve outgrown monolithic. Most mid-market stores don’t need it. Don’t pick headless because a conference talk said it’s the future; pick it because you’ve hit a ceiling.
№ 02Is headless faster than monolithic?
Usually yes by 0.3-0.8s on LCP. The gap closes if monolithic is on Kinsta with aggressive caching. For most mid-market stores the speed difference doesn’t justify the cost difference.
№ 03Can I go headless later if I start with monolithic?
Yes. The commerce engine stays the same — you build a new frontend on top. Migration scope: $25K-$60K for a typical mid-market store.
№ 04What CMS do you use for headless content?
Storyblok, Sanity, or Payload depending on team preference. Storyblok is the best fit for marketers needing visual editing; Sanity for content-heavy editorial; Payload for full TypeScript control.
