Headless commerce, without assembling the stack yourself

What is headless commerce?

Headless commerce (sometimes called composable or API-first commerce) splits the customer-facing storefront from the systems that hold products, orders, customers and payments. Shoppers hit a frontend you control. Merchants keep working in a familiar admin. The two talk over APIs instead of a locked-in theme.

That split is what people mean when they search for a headless Shopify storefront, headless WooCommerce, or a Next.js commerce stack. You are not abandoning the engine. You are replacing the slow, template-bound layer shoppers actually see.

Why stores go headless

Monolithic platforms bundle theme, checkout, plugins and admin into one system. That is convenient until you need Core Web Vitals that win paid traffic, a PDP that matches the brand, a checkout that is not the default template, or content that lives in WordPress, Sanity or Contentful rather than a page builder.

• Performance: storefront speed is no longer capped by a heavy theme.
• Design freedom: PLP, PDP, content and checkout can be custom, not nearest-preset.
• Developer experience: iterate in Git on Next.js instead of a theme file graveyard.
• SEO and AEO: you control rendering, metadata, structured data and URL structure.
• Composable stack: keep Woo or Shopify, add the CMS, ESP and payments you already use.

Why most headless projects stall

Headless is not right for every catalogue, and it used to be out of reach for most teams. A typical custom build meant six months or more, a six-figure budget, and specialists across frontend, backend, DevOps and APIs. That is why many brands stay on a theme even when conversion has plateaued.

The work that kills projects is rarely the React. It is cart and checkout, webhooks, preview environments, hosting, and wiring commerce, content and payments into one storefront. HeadKit productises that layer so you spend time on UX, not on becoming a platform company.

How HeadKit makes headless practical

HeadKit is the cloud platform for building and shipping headless stores. You get a production Next.js Storefront cloned into GitHub, HeadKit Cloud for connections, and HeadKit Engine as a single API in front of commerce, content and payments. Hosting follows a Vercel path. Convert an existing WooCommerce or Shopify store, or start fresh.

• Keep the WooCommerce or Shopify admin your team already knows. No forced replatform of catalogue and orders.
• Ship a custom storefront and checkout you actually control, without writing a backend from scratch.
• Connect WordPress, Sanity or Contentful, Stripe or PayPal, and Klaviyo without a custom BFF on day one.
• Spin up in minutes on a free plan, then scale when the store earns it.

Choose your commerce engine

If you already run WooCommerce (or WordPress commerce), use HeadKit for headless WooCommerce: connect the existing shop or provision a new one on HeadKit Cloud.

If you already run Shopify, use HeadKit for headless Shopify: keep Shopify as the engine and skip starting from a blank Hydrogen app on Oxygen.

Headless options compared

A custom Next.js app on the Storefront API or WPGraphQL gives maximum control and maximum ownership of glue code. Shopify Hydrogen is an excellent React framework if you want to stay inside Shopify’s hosting and mental model. Faust.js is a WordPress-centric frontend. Medusa, Saleor, Payload and Swell are strong if you want to replace the commerce backend entirely.

HeadKit is for teams who want a custom Next.js storefront and managed integrations, but do not want to migrate off WooCommerce or Shopify or staff a platform team. Compare HeadKit vs Hydrogen, HeadKit vs Payload and HeadKit vs Swell if you are evaluating those stacks.

Who this is for

• Retailers who need a faster storefront without a new back office.
• Agencies who sell custom headless work and need a repeatable delivery platform.
• Developers who want a real Next.js repo, not a theme, and not a science project.
