Sylius - Open Source Headless eCommerce Platform
Sylius is Open Source Headless eCommerce Platform for mid-market and enterprise brands that need custom solutions.
Categories:
Sylius is a headless, open-source eCommerce platform built on Symfony, empowering developers to create highly customizable B2C and B2B shopping experiences.
๐ Overview
Sylius is a flexible, developer-first eCommerce framework that breaks free from the constraints of rigid platforms, allowing you to build tailored online stores with complete control over every aspect.
It solves the problem of inflexible, vendor-locked eCommerce solutions by providing decoupled, reusable components on top of Symfony, enabling headless architectures, custom frontends, and seamless integrations via a robust REST API.
Built for experienced PHP developers, agencies, and technical teams who demand unlimited flexibility, high-quality code, and modern best practices like BDD testing.
Sylius was created to restore the joy of eCommerce development, emphasizing components-based approach, simple customization, and community-driven innovation since its inception in Poland around 2010.
