Headless E-commerce

Ago Fitness. From a standard Shopify store to a 100% custom frontend built with Next.js.

We built the Ago Fitness storefront headless: Shopify as the commerce backend (catalog, checkout, inventory) via the Storefront API, with the entire frontend custom-built in Next.js — without the limitations of a theme.

THE CHALLENGE

Ago Fitness wanted an e-commerce with the polish of premium activewear brands (Lululemon, Alo Yoga, On Running) — a result a standard Shopify theme wasn't going to deliver without full control over the frontend.

THE SOLUTION
  • Headless storefront with Next.js 15 (App Router) + Shopify Storefront API for catalog and cart.
  • Navbar with animated mega menu and an in-place morphing search bar (GSAP Flip).
  • Footer with newsletter and a reusable button component with micro-interactions.
  • 100% Shopify checkout — no rebuilding payments, taxes, or shipping from scratch.

THE IMPACT

Store in launch phase — technical metrics measured with Lighthouse against the real production build. Conversion and traffic data will be added once the store is operating with real customers.

92/100 Performance Score

Measured with Lighthouse against the real production build — without the weight of a generic theme, the site loads fast from the first render.

0 Cumulative Layout Shift

Zero layout shift: every component reserves its space from the start, no flicker or reflow on load.

100% Headless

100% custom Next.js frontend — no dependency on a Shopify theme or its customization limits, with Shopify as a pure commerce backend.
