Headless Shopify and Medusa

We build headless storefronts on Shopify and Medusa. A custom Next.js frontend, with Shopify or Medusa running products, checkout, orders and inventory, and none of the limits of a theme.

What we do

Shopify or Medusa underneath. A storefront built for your brand.

Faster by Default

Static and server-rendered pages load instantly — no theme overhead.

Total Design Freedom

No template constraints — every pixel built to your brand spec.

Shopify or Medusa

Shopify when you want its checkout and operations. Medusa when the commerce engine should live in your own stack.

Built to Scale

FAQs

Further details about our Headless eCommerce offering

Get in touch
Can headless ecommerce integrate with ERP, PIM, and CRM systems?+

Yes. We connect Shopify and Medusa storefronts to ERP, PIM, CRM, stock and fulfilment so pricing, orders and customer data stay aligned.

Can we keep Shopify while moving to a headless frontend?+

Yes. Shopify can keep products, orders, payments and checkout, while we build the storefront in Next.js. If the commerce engine needs to live in your own stack, we build the same kind of storefront on Medusa.

What is headless ecommerce and when should we use it?+

Headless ecommerce is a custom Next.js storefront, with Shopify or Medusa running products, checkout, orders and inventory. Use it when a theme is limiting the experience, the speed, or the way the store needs to sell.

Will headless ecommerce improve site speed and SEO?+

Usually yes. A Next.js storefront on Shopify or Medusa drops the theme overhead, which improves Core Web Vitals and gives technical SEO a cleaner base.
