Open-source E-Commerce Platform
"Shopware 6 is an open-source ecommerce platform based on a modern tech stack. It's the successor of the very successful e-commerce shopping cart Shopware 5 which has over 800000 downloads.
Shopware 6 is focused on an API-first approach, so it's quite easy to think in different sales channels and make ecommerce happen wherever you want it.
Shopware 6 uses Symfony, and the admin interface is completely based on Vue.js."
