Sylius is a headless open-source eCommerce framework built on top of Symfony and API Platform that enables developers to create custom, API-driven shopping experiences.
Sylius addresses the need for flexible, business-specific eCommerce solutions by providing a Symfony-based framework with a powerful REST API at its core. Rather than forcing merchants into predefined workflows, the framework emphasizes customization and integration. It employs a full-stack Behavior-Driven-Development approach using PHPUnit and Behat, establishing a strong testing culture that supports maintainability as projects grow.
The tool suits teams building tailored eCommerce applications where off-the-shelf solutions fall short. It works well for projects requiring headless architecture, multi-channel experiences, or deep integrations with existing systems. Sylius Plus offers modular add-ons including OnePageCheckout, B2B capabilities, multi-store management, partial order fulfillment, returns handling, loyalty systems, and multi-source inventory for teams needing advanced features beyond the core framework. The project maintains a plugin marketplace where community extensions can be discovered and installed.
Development activity shows consistent engagement with the codebase through regular contributions and active maintenance of the framework's core systems. The project maintains organized communication channels including Slack and Stack Overflow for community support, alongside professional support options through Sylius Plus. Security issues are handled through a dedicated email process rather than public issue tracking, indicating a structured approach to vulnerability management. The project actively encourages community participation through a documented contributing guide and maintains a marketplace ecosystem for third-party extensions.
