Sylius

Sylius provides a full‑stack eCommerce framework built on Symfony, delivering a codebase that follows behavior‑driven development practices with PHPUnit and Behat. It includes a REST API that enables integration with external systems and the creation of custom shopping experiences across devices. The platform is self‑hostable, free to use under the MIT license, and does not require a subscription, making it suitable for developers who want to maintain complete control over their deployment.

The framework targets developers and teams building tailored eCommerce solutions for mid‑market and enterprise brands. Its modular architecture allows the addition of features such as one‑page checkout, B2B capabilities, multi‑store management, partial order fulfillment, returns handling, loyalty programs, and multi‑source inventory through optional Sylius Plus modules. A marketplace of plugins and extensions further expands functionality.

Documentation is available online, and community support is offered via Slack, Stack Overflow, and a professional SLA option for Plus license holders. Security reports are directed to a dedicated email address, and contributions are welcomed through a public contributing guide.
