Sylius
Pending verificationHeadless open-source commerce platform for PHP/Symfony — a Polish alternative to Magento.
Overview
Sylius is a Poznań, Poland-based European company building developer tools, e-commerce, and open source software since 2011. As an EU-headquartered provider, Sylius likely operates under GDPR, though EU Alts has not yet independently verified its ownership and hosting facts, so its exposure to the US CLOUD Act isn't confirmed yet — see the Details section below for what's known so far.
Why European teams pick Sylius
Teams in Europe consider Sylius when they want a developer tools provider that bills in EUR and keeps customer data under Poland law, operating since 2011. Its EU headquarters is a good sign compared with GitHub, Atlassian, and JetBrains's US-distributed peers, but EU Alts hasn't yet verified Sylius's ownership and hosting facts — check back once verification is complete.

About
Sylius is a Polish open-source e-commerce framework built on Symfony, founded in Poznań in 2011, designed for custom and headless commerce applications. Unlike PrestaShop or Shopware, Sylius is a developer-first framework rather than a ready-made shop — it provides the building blocks (product catalogue, orders, payments, shipping) that developers assemble into custom commerce applications. It is released under the MIT licence and is self-hostable on any EU server. Sylius is popular among European development agencies and enterprises that need a highly customisable, EU-hosted e-commerce platform for B2B, subscription, marketplace, or multi-tenant commerce scenarios where out-of-the-box solutions are insufficient.

Frequently asked questions
What is Sylius?
Sylius is a Polish open-source e-commerce framework built on Symfony, founded in Poznań in 2011, designed for custom and headless commerce applications. Unlike PrestaShop or Shopware, Sylius is a developer-first framework rather than a ready-made shop — it provides the building blocks (product catalogue, orders, payments, shipping) that developers assemble into custom commerce applications. It is released under the MIT licence and is self-hostable on any EU server. Sylius is popular among European development agencies and enterprises that need a highly customisable, EU-hosted e-commerce platform for B2B, subscription, marketplace, or multi-tenant commerce scenarios where out-of-the-box solutions are insufficient.
What does Sylius do?
Sylius is headless open-source commerce platform for php/symfony — a polish alternative to magento. It is listed under developer tools, e-commerce, and open source on EU Alts because its core functionality serves teams looking for a European developer tools tool with EU data residency, typically as a switch away from GitHub, Atlassian, and JetBrains's US-distributed peers.
Is Sylius a good European developer tools alternative?
Sylius is a fit for European businesses evaluating developer tools options where data residency and GDPR alignment matter — typical buyers include EU-based SaaS teams, public-sector projects, regulated industries (healthcare, finance, legal), and any organisation that needs to demonstrate that customer data does not leave the EU. It also overlaps with e-commerce and open source use cases.
Is Sylius GDPR compliant?
Sylius is headquartered in Poznań, Poland and falls under EU jurisdiction, so it likely processes user data under the GDPR by default. Customer data processing is supervised by Poland's data protection authority, the Urząd Ochrony Danych Osobowych (UODO). EU Alts has not yet independently verified Sylius's ownership structure or hosting location, so we can't yet confirm its exposure to the US CLOUD Act the way we can for verified entries.
How do teams switch from GitHub to Sylius?
Most teams considering a move from GitHub, Atlassian, and JetBrains's US-distributed peers to Sylius are drawn to its EU headquarters and developer tools workflow fit. EU Alts hasn't yet verified Sylius's ownership and hosting facts, so treat any CLOUD Act or Schrems II conclusions as provisional until verification is complete. Plan a migration in stages regardless: export your data from the US incumbent, pilot Sylius with a small team, then move the rest once integration coverage is confirmed.
Where is Sylius based?
Sylius is headquartered in Poznań, Poland. The company was founded in 2011. Its main website is https://sylius.com.
