OpenCart alternatives, European ones first →

Read this page as one judge. Each weighs the same scores by what they care about.

The Data Protection Officer

Weighted verdict

The shop holds customers, addresses and buying histories, and the checkout is full of third parties. Wants the subprocessor list, consent handling that survives a complaint, deletion that executes against order history, and an answer on where the CDN and analytics sit.

Same scores as the panel view — this lens weights them the way this judge cares.

Catalogue & checkout

How this is scored

Products, variants, pricing rules and the path to payment — the part that either converts or does not.

0 — Not a shop: no product catalogue and no checkout of its own.

3 — A product catalogue with categories and a checkout that takes payment through at least one provider.

5 — Products with variants, discounts or vouchers, guest checkout, and several payment methods including those German buyers expect (PayPal, invoice or direct debit) through named providers.

8 — Tiered and customer-group pricing, bundles or configurable products, rule-based promotions, per-channel or per-market pricing, abandoned-cart recovery, a checkout customisable without a rebuild, and buy-now-pay-later where offered.

10 — Merchandising and checkout are the product: rule-driven pricing and promotions, A/B-testable checkout, multi-currency and multi-language as standard, and conversion features (abandoned cart, one-page checkout) shipped rather than bolted on.

Report an error

The Data Protection Officer

The catalogue is richly documented: variants, per-option pricing, quantity-tier discounts, customer-group pricing, coupons, reward points and multi-store, multi-language assignment, with bank transfer and cash-on-delivery bundled and gateways such as PayPal documented as extension examples. The checkout path itself is thinly covered: we found no public information on guest checkout, abandoned-cart recovery or buy-now-pay-later, and with a checkout full of third-party gateways I would want far more about that path before trusting it with customer data. 2 3 6 8

Extensibility & developer surface

How this is scored

Themes, apps, APIs and headless — whether the shop can be shaped to the business, and at what cost in lock-in.

0 — A closed shop builder: no themes to edit, no apps or plugins and no API.

3 — Themes adjustable in an editor and a set of apps or plugins to add features.

5 — Custom themes with a template language or code access, an app or plugin ecosystem, and a documented API with webhooks for order events.

8 — A storefront API for headless builds, an extension framework with its own lifecycle, staging or development environments, version control for themes, and documented rate limits.

10 — A platform a team can own: headless-first APIs, open-source or source-available core, plugin architecture with a real dependency model, local development and CI supported, and upgrade paths that do not orphan customisations.

Report an error

The Data Protection Officer

The GPLv3 open-source core, Twig templating with both a web-based editor and a custom theme directory, an events-and-OCMOD extension model that avoids core edits, a documented extension packaging and installer lifecycle, and a Docker development environment make this a platform a team can shape and run locally. We found no public information on a documented storefront API, webhooks for order events, headless operation or rate limits. 1 6 7

Report an error

Order operations & back office

How this is scored

What happens after checkout: order management, stock, returns, shipping, and the link to ERP or accounting.

0 — No order handling in the product; orders leave as emails or exports to be processed elsewhere.

3 — An order list with statuses, stock counts per product, and shipping rates set up in the shop.

5 — Order management with status emails, stock tracking, named carrier integrations or label printing, and refunds or returns handled in the system.

8 — Partial shipments and partial refunds, multi-warehouse or multi-location stock, multi-channel or marketplace order intake, fulfilment routing, dropshipping, and maintained interfaces to named ERP and accounting systems (DATEV among them for German merchants).

10 — The shop is the front of an operation: real-time stock across channels and warehouses, returns and refunds fully worked including partials, ERP integration the vendor maintains, and operational reporting a merchant runs the business from.

Report an error

The Data Protection Officer

Order management is well evidenced: a central order hub with full statuses, editing of customer details, products, totals and shipping, manual order creation, bulk invoice printing, status-change emails and subscription handling, plus a returns system covering full and partial refunds, store credit, exchange and repair with return analytics. We found no public information on named carrier integrations or label printing, multi-warehouse stock, marketplace order intake or interfaces to ERP and accounting systems such as DATEV. 3 8 9

Report an error

Data ownership & exit

How this is scored

Whether the catalogue, customers and order history remain the merchant's: export completeness, hosting choice, and what leaving actually costs.

0 — The terms state that the merchant's data cannot be exported or is not returned on cancellation.

3 — CSV export of products and customers, or of orders, from the admin.

5 — Export of catalogue, customers and orders documented (CSV, API or dump), with data deletion or return on cancellation stated in the terms or help centre.

8 — Full-fidelity export including media and order documents, a documented migration path in and out, self-hosting or a choice of hosting partner, and no metering that prices a migration out of reach.

10 — Ownership is structural rather than promised: open-source or source-available platform the merchant can run anywhere, database-level access, documented migration in both directions, and contractual data return.

Report an error

The Data Protection Officer

Ownership is structural rather than promised: the platform is free under GPLv3, the merchant runs the database in the documented environment, and theme overrides and settings live in the database with explicit guidance to include them in migration backups. We found no public information on export tooling for catalogue, customers and order documents, or on contractual data return on cancellation, so an exit rests on the merchant's own database work. 1 7

Report an error

European sovereignty

How this is scored

Where customer and order data live, who the contracting entity is, and which subprocessors sit in the checkout path. Independently sourced by the sovereignty pipeline. Dimensions the evidence does not establish are unknown, not non-EU.

0 — Proven non-EU on every dimension the evidence covers: non-EU vendor and contracting entity and non-EU hosting, with no EU option stated.

3 — One European element proven — an EU hosting option, an EU contracting entity or EU representative, or a published DPA — with the rest of the chain unstated.

5 — EU hosting stated as standard or selectable and an EU contracting entity or EU representative, with a DPA offered; the subprocessor chain (CDN, analytics, payment routing, support tooling) is unstated or partly non-EU.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessor list published with locations, any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting and every subprocessor European, certification published, and a self-hosted option that puts the shop entirely under the merchant's control.

Report an error

The Data Protection Officer not rated — no public information

We found no public information on the vendor's jurisdiction or contracting entity, hosting or data-residency options, a data-processing agreement, or the subprocessor chain behind CDN, analytics and payment routing; every sovereignty dimension is unknown in the captured pages. Unknown is not non-European, so I score nothing here and report it as unevidenced. 1

Report an error

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a merchant can compute the real annual cost — licence, transaction fees, apps, hosting — from public pages alone. The category where the headline price is least often the invoice.

0 — No public prices at all; every tier is a sales conversation.

3 — A public "from" price or one priced tier.

5 — Prices for the main tiers public with the billing period stated and the main inclusions per tier listed.

8 — Every tier priced publicly including transaction or revenue-share rates, order or GMV limits, and the cost of the extensions most shops need; VAT treatment and minimum term stated.

10 — Complete price computability: annual cost derivable for a given order volume and GMV including licence, transaction fees, hosting and typical extensions — and for open-source platforms, an honest statement that the licence is free and where the money actually goes.

Report an error

The Data Protection Officer

The captured pages state plainly that the platform is free and open source under GPLv3, which makes the licence cost transparent and, for an open-source platform, is the honest statement about where the licence money goes. We found no public information on the cost of typical extensions, themes, hosting or paid support, so the real annual cost of a running shop cannot be computed from these captures alone. 1 6
