Webcellent GmbH

Shopware stores built to scale cleanly – by developers, not salespeople

Webcellent GmbH, based in Bielefeld, Germany, has been operating since 2015 and is led today by owner and managing director Christopher Diamant. Webcellent is a team of four developers from the OWL region and northern Germany with more than 60 years of combined digital experience – specialized in Shopware, Shopify, custom software, and system integrations. No bloated agency setup: direct contact with the development team, clear responsibilities, and honest consulting.

We treat Shopware not as a website, but as an e-commerce operating system

A good Shopware store is more than a theme and product pages. What matters is how cleanly product data, processes, integrations, performance, technical SEO, and conversion work together. That is exactly where we come in: we assess whether the standard feature set, a plugin, or custom development is the right solution – and build stores that don't need to be rebuilt from scratch at the next stage of growth.

Our team speaks fluent Shopware – certified and proven in real projects

We are a certified Shopware Partner (Bronze) with Shopware 6 developer certifications on the team. Our track record includes WooCommerce migrations, Shopware 5 to 6 migrations involving external system integrations, and a high-load platform handling up to 200,000 requests per hour. You can find a selection of our projects in the references on our Shopware page.

Development, integrations & technical SEO from a single source – no friction

Many e-commerce projects suffer from friction between design, development, and SEO providers. Not with us: URL structure, 301 redirects, canonicals, structured data, index management, and tracking are part of our process from day one – instead of being retrofitted later. That saves budget and protects your organic visibility, especially during relaunches and migrations. Learn more on our e-commerce overview page.

Get to know us

In a free initial consultation, we take a look at your project together and give you an honest assessment of scope, effort, and a sensible approach – no sales pressure, just a straightforward evaluation. Your inquiry goes directly to Christopher and is answered personally.
