Best Open-Source European Ecommerce Platforms (2026)

An open-source ecommerce platform publishes the source of its core under a licence that allows you to run, modify and host it yourself, which means the shop can be moved to different infrastructure without being rebuilt.

How we rank these tools — 4-step process

1
European ownership, verified
The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.
2
Category fit and hands-on review
What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.
3
Compliance and pricing check
GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.
4
Position on this page
Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect the order in which tools appear; it never affects whether a tool is listed. Editorial policy

How we review

Key takeaways

Shopware offers the most complete open-source core here, with commercial editions above it, which is why it suits merchants who want the exit without giving up support.
Sylius is the most permissively licensed at MIT, and the most explicitly designed to be modified rather than configured.
PrestaShop is the easiest to actually self-host without a development team, which for a small merchant is the difference between open source in principle and in practice.
Saleor gives you an open core with a GraphQL API, so moving between Saleor Cloud and your own infrastructure is a change of endpoint rather than a migration.
Open source does not mean free: hosting, updates, security patching and module licences are the real cost, and a platform nobody operates is a liability rather than a saving.

Open source in ecommerce is insurance rather than a saving: somebody still has to operate hosting, updates and security patches. What it buys is the ability to leave — a platform that raises its price or changes its terms cannot strand a shop whose code you already hold. This ranking judges five European platforms on licence, on how real the self-hosted path is, and on what running it actually takes.

The 5 tools reviewed

#1 Shopware

Schöppingen, Germany Open source + paid editions Demo on request

Best for: An open core with a commercial safety net

Operating company. Shopware
Jurisdiction. EU (Germany)
Source code. Closed source
Replaces. Shopify Plus, Adobe Commerce, BigCommerce

Shopware’s Community Edition is genuinely usable in production rather than a crippled demo, and the commercial editions add support, the B2B suite and managed hosting on the same codebase. That combination is unusual: most vendors either publish everything or hold back the parts that matter.

For a merchant, the practical value is that the exit exists without having to take it. You can run the commercial edition and still hold code you could host yourself if the relationship ended.

What Shopware does well

Production-grade open core
Commercial editions on the same codebase
Established hosting partner ecosystem

Where Shopware falls short

B2B suite requires a paid edition
Needs real technical capacity to self-host well

Standout feature. An exit route you do not have to use — the commercial edition runs on code you could host yourself.

#2 PrestaShop

Paris, France Open source + hosted plans Demo on request

Best for: Self-hosting without a development team

Operating company. PrestaShop
Jurisdiction. EU (France)
Source code. Closed source
Replaces. Shopify, WooCommerce, BigCommerce

PrestaShop is the most realistic self-hosted option for a merchant without engineers. It installs on ordinary shared or managed hosting, the back office is aimed at shop owners rather than developers, and the module marketplace covers most requirements without custom code.

That accessibility is why it runs hundreds of thousands of shops. The trade is that module quality varies and updates need attention — open source moves the maintenance to you regardless of how friendly the interface is.

What PrestaShop does well

Installs on ordinary hosting
Back office aimed at merchants
Enormous module marketplace

Where PrestaShop falls short

Module quality is uneven
Updates and security are your responsibility

Standout feature. The one on this list a merchant can genuinely self-host without hiring anyone.

#3 Saleor

Wrocław, Poland Open source + Saleor Cloud Demo on request

Best for: An open core behind a modern API

Operating company. Saleor
Jurisdiction. EU (Poland)
Source code. Closed source
Replaces. Shopify Plus, commercetools, BigCommerce

Saleor publishes an open-source core with the same GraphQL API that Saleor Cloud serves, so the hosted and self-hosted paths are the same software. For a team that wants managed hosting now and the option of moving later, that removes the usual migration risk.

It is Python and Django underneath, which is a different operational profile from the PHP platforms here — relevant if your team already has one stack or the other.

What Saleor does well

Hosted and self-hosted are the same software
GraphQL API across the domain
Python and Django stack

Where Saleor falls short

No storefront included
Smaller ecosystem than the PHP platforms

Standout feature. Moving from the vendor’s cloud to your own is a change of endpoint, not a migration.

#4 Odoo

Ramillies, Belgium Founded 2005 One free app / paid plans per user per month Demo on request

Best for: An open core across the whole business, not just the shop

Operating company. Odoo S.A.
Jurisdiction. EU (Belgium)
Where the data sits. EU hosting (Odoo Online) or your own servers
Source code. Open source
Replaces. NetSuite, Microsoft Dynamics 365 Business Central, Sage

Odoo’s core is open source and self-hostable, and the shop is one app among inventory, purchasing, accounting and CRM. For a company that wants its whole operational stack on code it holds, that is a broader guarantee than an ecommerce platform alone.

The Enterprise edition adds features on top, and several things merchants expect sit there rather than in the community version — worth checking against your requirements before assuming the open core is enough.

What Odoo does well

Open core across the entire suite
Self-hostable including the shop
Very large community module ecosystem

Where Odoo falls short

Several expected features are Enterprise-only
Suite is complex to operate

Standout feature. Open source across the shop, the stock and the ledger rather than the shop alone.

#5 Sylius

Łódź, Poland Open source + Sylius Plus Demo on request

Best for: Maximum licence freedom and maximum modification

Operating company. Sylius
Jurisdiction. EU (Poland)
Source code. Closed source
Replaces. Adobe Commerce, Shopify Plus

Sylius is MIT-licensed, which is the most permissive licence in this comparison, and it is built to be extended rather than configured. Every part is idiomatic Symfony a PHP team can read, override and test with the tools they already use.

That freedom assumes a development team. Sylius is an agency and in-house-engineering choice; a merchant looking to install a shop should look at PrestaShop or Shopware instead.

What Sylius does well

MIT licence, the most permissive here
Designed for modification
Idiomatic Symfony throughout

Where Sylius falls short

Requires a PHP team
Sylius Plus is a commercial licence

Standout feature. MIT-licensed and built to be overridden — the least constrained option in the category.

What does open source actually buy a merchant?

Not primarily cost. Hosting, updates, security patching and module licences add up, and a well-run self-hosted shop is rarely dramatically cheaper than a managed plan once someone’s time is counted.

What it buys is the exit. A shop on a proprietary platform that raises its price, changes its terms or discontinues a tier has to be rebuilt; a shop on an open core can be moved to different hosting with the same code. For a business whose revenue runs through that checkout, that difference is the whole argument.

It also buys inspection. You can read what the platform does with customer data rather than relying on a data processing agreement, which for some regulated merchants is the deciding factor.

What does self-hosting actually require?

Hosting sized for your traffic, with a staging environment — deploying an untested update straight to a live shop is how open source earns its bad reputation. Backups that have been restored at least once. And someone responsible for applying security patches within days rather than quarters.

PrestaShop is the most forgiving of the five: managed hosting providers offer one-click installs and handle much of this. Shopware and Sylius assume more capability. Saleor assumes a Python operational stack.

The honest question is not whether you can self-host but who will, and what happens when they leave.

Is the open edition crippled?

It varies, and this is the thing to check before committing. Shopware’s Community Edition is production-grade, with the B2B suite and support in the paid editions. Sylius’s MIT core is complete, with enterprise features in Plus. Saleor’s core is the same software as its cloud.

Odoo is the one to look at hardest: several features merchants expect sit in the Enterprise edition rather than the community one. That is a legitimate business model, not a criticism — but assume nothing and check against your actual requirements.

How we selected and ranked these 5 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
Editorial review. Three people touch every page: one writes it, a second edits it, and a third checks the compliance and pricing claims against the vendor's documentation. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

Which European ecommerce platforms are open source?

Shopware, PrestaShop, Saleor and Sylius all publish an open-source core you can download and host yourself, and Odoo’s core is open too. Each has commercial editions or managed cloud above the open version, which is the usual model and generally a healthier one than pure open source with no vendor behind it.

Is open-source ecommerce cheaper?

Not necessarily, once hosting, updates, security patching and module licences are counted. The saving is real for shops with in-house capability and largely illusory for shops without. What open source reliably buys is not a lower bill but an exit — the shop can move to different infrastructure without being rebuilt.

Which is easiest to self-host?

PrestaShop, by a distance. It installs on ordinary managed hosting, the back office is designed for merchants rather than developers, and one-click installs are widely available. Shopware and Sylius assume more technical capability, and Saleor assumes a Python operational stack.

What licence do these platforms use?

Sylius uses MIT, the most permissive here. Shopware, PrestaShop, Saleor and Odoo use their own open-source licences with commercial editions above them. If licence terms matter to your business — redistribution, modification, hosting for third parties — read the specific licence rather than relying on the phrase open source.

Can I start hosted and move to self-hosted later?

Saleor makes this cleanest: the cloud runs the same software as the open core, so moving is a change of endpoint. Shopware’s commercial editions run the same codebase as the Community Edition. That option is worth confirming explicitly with any vendor, because "open source" and "the same software we host" are not always the same claim.
