Sylius is an open source eCommerce framework built on Symfony that lets development teams build fully customized online stores with complex product catalogs, B2B pricing, and headless commerce capabilities without Shopify's customization limits or Magento's licensing costs.
The Problem
Shopify's closed architecture limits teams that need deep customization of checkout, pricing logic, or product structures. Magento (Adobe Commerce) covers enterprise requirements but carries steep licensing costs and operational complexity. Teams building B2B marketplaces, multi-currency stores, or custom pricing tiers often find both platforms too limiting or too expensive for their use case.
How Sylius Solves It
Sylius is built as a set of Symfony bundles and components, making every part of the platform overridable through standard Symfony extension mechanisms. The REST API supports headless commerce use cases. Product catalog, pricing, inventory, and checkout are all customizable at the code level without patching vendor files. MIT licensed.
Key Features
- Headless commerce REST API for decoupled frontend development alongside server-rendered storefronts
- Flexible product catalog with configurable product variants, custom attributes, and pricing tiers
- Multi-channel and multi-currency support for international or B2B store configurations
- Symfony-native architecture: extend any part of the platform using standard bundle override patterns
- Promotions, discount rules, and coupon management with composable promotion calculators
- MIT licensed with no per-transaction fees; runs on any PHP hosting or Docker
Who It's For
Sylius is best for PHP and Symfony development teams building complex eCommerce projects that exceed Shopify's customization limits, particularly B2B stores with custom pricing, multi-channel operations, or technical requirements that demand full control over the checkout and catalog logic.
Compared to Shopify
Unlike Shopify, Sylius runs on your own infrastructure with no per-transaction fees and no restrictions on checkout customization. Shopify offers faster time-to-launch and a rich app marketplace; Sylius requires a PHP development team but gives full control over pricing logic, product modeling, and checkout flow that Shopify Plus cannot replicate.
