Sylius vs Shopware: which architecture should you choose for your future e-commerce site?

In the PHP ecosystem, there are many tools for building an e-commerce site. Let's look at two of them: Sylius and Shopware. Although they share the same technology stack, their philosophies differ radically.

Choosing one or the other is not just a question of features: it is a strategic decision that will affect your business flexibility and your long-term maintenance costs. Let's break it down.

1. Two philosophies, two approaches to e-commerce

Sylius: the “Framework” for tailor-made projects

Sylius is not a “turnkey” solution in the traditional sense. It is a specialised framework. On installation, you get the essential building blocks, but the platform is designed to be shaped by a development team. It is the tool of choice for projects where the business must dictate how the tool works, and not the other way round.

Shopware: the ecosystem-oriented “Product”

Shopware offers a more packaged approach. Strongly oriented towards plugins and apps, it is increasingly moving towards a SaaS (Software as a Service) model. It is a robust solution that lets you launch features quickly thanks to its marketplace, while also offering a self-hosted version for more control.

2. Extending the system: SaaS vs Self-Hosted

The choice of extension architecture is the breaking point between the two tools:

The Shopware approach (SaaS vision): through its app model, Shopware offloads business logic to third-party services via webhooks and APIs. This is ideal for scalability, but it limits customisation to the extension points provided by the vendor.

The Sylius approach (Framework vision): here, pure “SaaS” is more complex to implement because Sylius focuses on flexibility. Customisation happens at the heart of the code, offering total freedom.

Did you know? If you host Shopware yourself, you can use plugins (similar to Symfony bundles). Be careful, though: piling up third-party plugins can make your future upgrades more complex, an issue Symfony developers knew well in the “everything is a bundle” era of Symfony 2.

3. Technical comparison: under the hood

Although both use Symfony, they handle data and the interface differently:

Feature	Sylius	Shopware
Data management	Doctrine ORM (Symfony standard)	Proprietary abstraction layer (DAL)
DB changes	Model overriding (flexible)	Configuration & dedicated tables (rigid)
Frontend	Full customisation “from scratch”	Inheritance-based theme system
Search	To be added (Elasticsearch, Algolia…)	Native (Elasticsearch/OpenSearch required)

The critical point: in Shopware, search is natively integrated, which speeds up time to market. In Sylius, this building block has to be built or integrated via a plugin, which requires more initial effort but lets you choose a perfectly tailored solution (such as Meilisearch or Algolia).

4. How to make the right choice?

The final choice depends on your team and your strategic vision:

Opt for SaaS (Shopware Cloud) if you want to delegate technical maintenance and adapt your business processes to existing tools.

Opt for self-hosting (Sylius or Shopware Self-hosted) if you have specific business needs, complex data flows or want to control your infrastructure from A to Z.

Why get expert support?

Whatever tool you choose, the success of your project depends on the quality of the implementation. A poorly designed e-commerce application quickly turns into costly technical debt.
