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

The Skeptic

Weighted verdict

Knows the headline price is never the invoice here. Reads for the transaction fee, the apps that turn out to be mandatory, the hosting nobody mentioned, and what the platform charges to let a merchant leave with their own order history.

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 Skeptic

The catalogue side is genuinely strong: variants, per-option pricing, quantity tiers, customer-group pricing, special pricing and per-store discounts are all documented, and coupons appear in order handling. The checkout side is thin — the default bundle ships bank transfer and checkout on delivery, with PayPal named only as an example of an installable extension type, and we found no public information on guest checkout, German payment methods, abandoned-cart recovery or buy-now-pay-later in the captured pages. 2 3 6 8

Report an error

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 Skeptic

GPLv3 source, Twig custom themes, a structured extension system with install.json, MVC-L, events and OCMOD, and a Docker development environment are real and documented. Nothing captures a storefront API or webhooks for external order events, and the theme editor actively works against version control: overrides live in the database, there is no built-in revert, and multiple administrators editing the same template means last save wins. 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 Skeptic

Orders are documented as a full working hub — editing, manual creation, status-change emails, bulk invoice printing, subscription tracking — and returns are worked through completely with statuses, configurable reasons, full and partial refunds and return analytics. We found no public information on carrier integrations or label printing (UPS appears only as an example extension type), multi-location stock, marketplace intake, or interfaces to ERP or accounting systems such as DATEV. 3 6 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 Skeptic

Ownership is structural rather than promised: GPLv3, free download, and a stack the merchant runs themselves with MariaDB, so the catalogue and order history sit in the merchant's own database. But the captured pages document no export tooling or migration path in either direction, and the warning that theme overrides live in a database table you must remember to include in a backup shows that leaving cleanly depends on the operator's diligence. 1 7

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 Skeptic not rated — no public information

We found no public information on the vendor's legal jurisdiction, data residency, hosting arrangements, a data processing agreement or any subprocessor in the checkout path — every sovereignty dimension is unknown on the captured pages. The code repository confirms free open-source software, which speaks to who can run it but tells a buyer nothing about who processes data or where; I therefore report this criterion as unevidenced rather than score it. 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 Skeptic

The licence is stated honestly and publicly as free open source under GPLv3, so there are no headline games in the licence line itself. But we found no public information in the captured pages on hosting costs or marketplace extension prices, which is where the real annual invoice lives for a self-hosted platform, so a merchant cannot compute their true yearly cost from these pages alone. 1
