About Sylius

Sylius is an open-source ecommerce framework built on Symfony, described as headless and based on PHP, Symfony and API Platform. It targets developers who need an online store tailored to specific business requirements rather than a fixed, off-the-shelf shop.

The code base is developed with full-stack behavior-driven development, using PHPUnit and Behat, and the project stresses code quality and testing culture. A REST API makes it possible to integrate the store with other systems and build customer experiences on any device. Installation is done through Composer, documentation lives at docs.sylius.com, and community support is available through Slack and Stack Overflow.

Sylius is licensed under MIT. The company also sells Sylius Plus, a commercial edition with modular features such as one-page checkout, a B2B suite, multi-store management, partial order fulfillment, returns handling, loyalty features and inventory spanning multiple sources, along with SLA-backed support. Plugins are available from the Sylius Store marketplace.
