Headless Commerce
Next.js frontend.Maximum performance.
Headless e-commerce for 50M+ PLN GMV stores. Next.js + Shopify Storefront API or Medusa.js. LCP < 1s on Edge, per-segment personalization, omnichannel from one API.

Headless advantages
Why headless
wins at scale.
Performance without compromise
LCP < 1s on Edge, INP < 50ms. React Server Components minimize browser JS. ISR refreshes cache in background — pages always up to date and instant.
Omnichannel from one API
The same backend serves web, mobile (React Native), kiosk, PWA and B2B integrations. One source of truth for products, prices and stock levels.
Per-segment personalization
Edge Middleware personalizes content per user before rendering. A/B testing at infrastructure level, not JavaScript.
Composable architecture
Replace any layer independently — change payment provider, CMS, search engine without rebuilding the whole store. Future-proof from day one.
Security through separation
Frontend has no access to database and business logic. Everything via API with tokens. Smaller attack surface, easier compliance.
Scaling without limits
Edge functions auto-scale to millions of requests. Black Friday requires no infrastructure preparation. Pay for actual usage.

FAQ
Headless questions.
Headless commerce vs traditional store — when is it worth it?
Headless makes sense at 50M+ PLN GMV/year, when: you need performance impossible on a monolith (LCP < 1s on edge), you sell multi-channel, you need advanced personalization or have a dev team that will develop the system. For stores below 50M GMV the ROI from headless is often not justified — Shopify or WooCommerce are a better choice.
Shopify Storefront API vs Medusa.js — which to choose?
Shopify Storefront API: proven ecosystem, app marketplace, faster start. Good if you want a headless frontend but proven commerce backend. Medusa.js (open-source): full control, zero transaction fees, easy self-hosting, customizable. Good if you want your own code and infrastructure without vendor lock-in. Commercetools: enterprise grade, most expensive, for corporations.
What does maintaining a headless store look like after launch?
Headless requires a competent dev team to update Next.js, manage deployments and develop features. It's not "set and forget" like Shopify. We offer a technical retainer (from 8h/month) or training for your team. Monitoring (Sentry + Datadog) and regular performance audits are also key.
