Headless Shopify agency · Hydrogen, Next.js, Storefront API
Headless Shopify development agency in the USA: sub-second storefronts, checkout untouched.
We build custom storefronts on Hydrogen or Next.js, connected to Shopify’s Storefront API, for sub-second load times and complete design freedom — while Shopify still handles your checkout, inventory and orders exactly as it does today.

Headless Shopify agency · what it is
What a headless Shopify agency actually builds.
The difference from a theme is control: a blank canvas in front, Shopify’s commerce engine behind it.
Headless commerce separates your storefront — the part customers see and interact with — from Shopify’s backend, the part that handles checkout, inventory and orders. A custom frontend, built on Hydrogen or Next.js, pulls your product data through Shopify’s Storefront API, while Shopify keeps running everything underneath it.
The difference from a theme is control. A theme constrains you to what Liquid and app blocks allow. Headless gives you a blank canvas — any layout, any interaction, any framework — with Shopify’s commerce engine still doing the heavy lifting behind it.
That is what a headless Shopify agency is for: the custom frontend, the Storefront API layer that feeds it, the performance work that makes it fast, and the delivery to every channel you sell on — web, app and kiosk — from one catalog.
How it’s connected
One backend, any frontend.
Your storefront and your commerce engine become two independent pieces, connected by an API instead of a template.
Every channel
Web, app, kiosk
- Web storefront
- Mobile app
- In-store kiosk
One catalog, one cart, no duplicated product data.
Custom frontend
Hydrogen / Next.js
The storefront customers see — any layout, any interaction, built component by component and matched to your design files.

What’s included
Everything a headless build requires.
A headless project is more than a frontend rewrite. This is the full scope of what has to come together.
- 01
Custom frontend development

- Component-based architecture
- Pixel-matched to design files
- Fully responsive, tested on real devices
- 02
Storefront API integration
The layer that feeds it: GraphQL queries mapped to your catalog, the cart and checkout handoff, and live inventory and pricing.
- GraphQL Storefront API setup
- Cart & checkout handoff
- Real-time inventory & pricing
- 03
Performance optimisation
Server-side rendering and edge caching, image and asset delivery, and Core Web Vitals monitored after launch — not just on the homepage.
- SSR & edge caching strategy
- Image & asset optimisation
- Core Web Vitals monitoring
- 04
Omnichannel expansion
The same Shopify catalog and cart logic extended to a mobile app, kiosk or marketplace listing, without duplicating product data anywhere.
- Shared API across channels
- Mobile app & kiosk ready
- Consistent cart across surfaces
How we work
A fixed six-step process.
So architecture, integration and performance all get equal attention — and Hydrogen vs Next.js is decided before any code is written.
Discovery & architecture planning
We map your data model, channels and design requirements, and decide on Hydrogen vs Next.js before any code is written.
API & data modelling
Storefront API queries are mapped against your catalog structure — variants, metafields and collections included.
Frontend development
The custom storefront is built component by component, matched to your design files and tested in a live sandbox weekly.
Backend integration & testing
Cart, checkout handoff and account flows are connected and tested end to end against a real Shopify store.
Performance optimisation
Caching, image delivery and rendering strategy are tuned until every page hits its target Lighthouse score, not just the homepage.
Launch & monitoring
The storefront goes live, and we watch performance and API errors closely for the first weeks after launch.
How it’s built
The stack behind every headless build.
Picked per project in discovery, not by habit — Hydrogen or Next.js is decided before any code is written; the CMS only when your team needs to edit page content without a developer.

The guarantee
Headless without the usual risks.
Going headless changes your frontend, not your compliance surface.
- 01
Zero checkout risk
Checkout, payments and fraud protection stay entirely on Shopify. Going headless changes your frontend, not your compliance surface.
- 02
Zero admin disruption
Your team keeps managing products, inventory and orders in the exact same Shopify admin they already know.
- 03
Zero vendor lock-in
The frontend codebase is yours — clean, documented and portable, not hidden behind a proprietary page builder.
The proof
What speed actually buys you.
Every number here belongs to a named store.
Our product pages went from 4 seconds to under a second. Nobody thought our catalog was too complex for headless until we watched conversion climb after launch.

Straight answers.
What does a headless Shopify agency do?
It builds and runs the storefront separately from Shopify’s backend. Headless development separates what customers see from what handles checkout, inventory and orders: a custom frontend, built on Hydrogen or Next.js, pulls data through Shopify’s Storefront API, while Shopify still handles checkout, payments and order management. The agency owns the frontend, the API layer, performance and the delivery to every channel.
Do you work with brands across the USA?
Yes. We are a remote-first studio registered in Sheridan, Wyoming, with engineering in Lahore. Calls are scheduled in Eastern Time, every enquiry gets a written reply within 12 hours, and the engineer who scopes the build is the one who builds it.
Do I still use Shopify to check out with a headless build?
Yes. Headless changes the frontend, not the backend. Checkout, payments, taxes and fraud protection all stay on Shopify exactly as they are, so you keep every compliance and security guarantee that comes with it.
Is headless worth it for a smaller store?
Not always. Headless makes the most sense once you are hitting real theme limitations — custom UX requirements, multi-channel delivery, or performance ceilings a standard theme cannot clear. For most smaller catalogs, custom theme development gets you there without the added complexity, and we will say so.
How much faster is a headless storefront?
Most headless builds we ship land in the 90–100 range on Google Lighthouse, versus 40–70 for a typical app-heavy Shopify theme — translating to load times under a second on most pages.
What frameworks do you build headless storefronts on?
Primarily Shopify’s own Hydrogen framework or Next.js, both connected through the Storefront API and GraphQL, depending on your hosting preferences and existing tech stack.
How long does a headless build take?
A standard headless storefront typically takes 8 to 12 weeks. Multi-channel builds, custom checkout extensions or complex catalog logic can run 14 weeks or more.
How much does headless Shopify development cost?
Headless is quoted as one build: a fixed scope over 16–20 weeks — a Hydrogen or Next.js storefront on the Storefront API, a CMS, a documented design system, edge caching and the analytics stack — with one number written down before work starts. Where the store does not need headless yet, the Plus build tier runs $100,000–$200,000. Multi-storefront and omnichannel work is quoted the same way, as one build.
Can my team still manage products and content?
Yes. Product and inventory management stays entirely in Shopify admin. For page content, we typically connect a headless CMS so non-technical team members can update copy and layout without touching code.
Do I need Shopify Plus for a headless build?
No for most builds, though Plus unlocks Storefront API rate limits and checkout customisation options that matter for high-traffic or highly custom checkout requirements.
What happens after launch?
Every build includes a post-launch monitoring window covering performance regressions, API errors and deployment issues, with an ongoing support plan available for continued feature development.
What are the risks of going headless?
The ones we see are an API integration that quietly breaks, a caching layer that is not tuned, and a checkout handoff nobody tested end to end. Each is reviewed before launch, and checkout, admin and your codebase are covered by the guarantee above: zero checkout risk, zero admin disruption, zero vendor lock-in.
