Headless online store development

We build headless stores from scratch: a Next.js frontend (SSG/ISR) on an API-first Sylius/Symfony backend. Maximum speed up front, total flexibility in the back.

What the architecture looks like

Your data, the store engine and the storefront

Where we start

Your data

  • product catalogue
  • stock and prices
  • ERP or invoicing
  • the existing store, if any

The store engine

Sylius / Symfony

  • catalogue and stock
  • orders and payments
  • customers and accounts
  • integrations: ERP, couriers, invoicing

The storefront

Next.js

  • fast pages
  • SEO: URLs and indexable content
  • Core Web Vitals

Where the pages land

Your customers

  • phone
  • desktop
  • Google
The headless store architecture: your data (catalogue, stock and prices, ERP or invoicing) goes into Sylius / Symfony — catalogue, orders, customers, integrations —, Next.js builds the fast pages, and customers find them on phone, on desktop and in Google.

Next.js frontend

Static/ISR pages served instantly, optimized images and fonts, minimal JavaScript. A fast experience on any device and first-class SEO.

Sylius / Symfony backend

We model your exact business processes on a mature, API-first open-source core, without the compromises of a closed platform.

Tell us your store's address

We first take a free look at three pages (homepage, one product, the checkout) and send you the first 5 issues within two working days — sometimes the answer is "no, you're already fast".
