Headless eCommerce development

We build headless commerce where it pays off: a Medusa backend, a Next.js storefront, sub-second page loads and clean APIs for every channel. And we will tell you honestly in the Blueprint if headless is overkill for your case.

Headless eCommerce

Headless is an architecture decision, not a fashion statement

Separating the storefront from the commerce backend buys you three concrete things: page speed that monoliths cannot reach, freedom to serve any frontend, web, app, kiosk, marketplace, from one API, and deploys that touch one layer instead of everything at once. Those benefits are real, and so is the cost: more moving parts to own.

That is why our Blueprint treats headless as a trade-off to be earned, not a default. If your conversion is losing to Core Web Vitals, your roadmap includes multiple frontends, or the monolith makes every deploy a risk, headless pays. If not, we will say so and build you something simpler.

How we do it

01

Architecture Blueprint

We measure what you lose today (speed, deploy risk, channel limits) and design the target architecture with honest trade-offs.

02

Backend and API layer

Medusa modules expose clean APIs; business logic lives server-side, once, for every frontend.

03

Edge storefront

Next.js on the edge: sub-second loads, preview environments, deploys that ship daily without fear.

When it makes sense

01

Page speed and Core Web Vitals cost you conversions and rankings

02

You serve multiple frontends: store, app, kiosks, marketplaces

03

The monolith blocks your roadmap and every deploy is a risk

FAQ

Headless eCommerce development

What Core Web Vitals can we expect?

Green across the board is the norm for our headless builds: edge rendering, image optimisation and honest performance budgets enforced in CI.

Can marketing still work without developers?

Yes, content blocks, campaigns and collections are editable in the admin. Headless separates code from content; it does not take content away from your team.

Is headless always the right choice?

No, for a simple catalog it can be unnecessary complexity. The Blueprint weighs your team, roadmap and channels, and recommends headless only when it earns its keep.

What stack do you use?

Medusa.js as the commerce backend, Next.js on the storefront and Cloudflare on the edge, a stack we run in production, not a slide.

Does headless mean losing the admin panel?

No. Medusa ships a full admin, and we extend it with your modules, the team runs the store from one panel, as before.
