French and German leaders join forces in strategic partnership to bring flexibility and reliability to the European eCommerce market.

After three years of successful collaboration, Shopware, the German-based European leader in open-source eCommerce, and Upsun, the French-based leading European Cloud Application Platform, are announcing a strategic partnership.

Building on early success, with already 45 joint customers and growing, Shopware and Upsun are deepening their collaboration in 2026 and beyond. Together, they aim to address the multi-trillion-dollar European eCommerce market, combining the flexibility of open source with the power of an open cloud application platform.

This partnership delivers a unique European alternative to closed SaaS ecommerce ecosystems, empowering merchants to:

• Retain full control over their data ownership

“Digital sovereignty is not declared, it is built through cooperation and trust. Together with Shopware, we are giving European merchants a flexible, sovereign alternative that combines open source with an open cloud application platform.” said Fred Plais, CEO and Co-Founder of Upsun (formerly Platform.sh) “On Upsun, you retain control of your data, deploy on European cloud regions of your choice, avoid lock-in, and ship faster with predictable security and uptime. This Franco-German partnership is how Europe scales innovation by uniting talent around reliability, sustainability, and independence.”
