Magento checkout comparison: Magento 2 One Step Checkout Extensions compared in 2026: STM vs. Amasty vs. OneStepCheckout vs. Mageplaza Checkout

Last updated: July 2026. All information regarding third-party providers is taken from the respective official provider websites (sources at the end of the article) and is subject to change. We are the manufacturer of STM Smart One Page Checkout – this comparison therefore deliberately focuses on objectively verifiable facts: prices, licensing models, compatibility, and features.

Short answer: For those seeking a German-language provider with a one-time payment option, native Hyvä and Luma support, and an integrated EU right of withdrawal button, STM Smart One Page Checkout (€249) is a suitable solution. Amasty offers the largest add-on module ecosystem, OneStepCheckout the longest market history, and Mageplaza the largest review base.

STM Smart One Page Checkout – One-time payment, Hyvä + Luma, German support

The same question arises for WooCommerce — there the answer is STM Smart Checkout for WooCommerce: a one-, two- or three-column layout that leaves the payment methods, the legal plugin and the theme untouched and can be deactivated without leaving any residue.

The STM Smart One Page Checkout from Storetown Media (a Magento agency from Tornesch near Hamburg) costs €249 as a one-time payment. This includes 12 months of updates and support ; renewal is optional and offered at a 30% discount – the checkout continues to function even without renewal. A 30-day money-back guarantee is also included.

Strengths: The extension natively supports Hyvä and Luma in the same package – relevant for shops that are still planning a frontend migration and don't want to purchase or migrate the extension twice. Four switchable layout variations can be changed without template adjustments. As the only extension in this comparison so far, it features an integrated EU cancellation button, as required by EU consumer rights regulations for online shops since June 19, 2026 – a compliance issue for merchants with EU end customers that would otherwise have to be addressed separately. Support is available in German and English, and Magento versions 2.3.x to 2.4.9 are supported. It supports PayPal, Mollie , Stripe, Klarna, Adyen, PayOne, Unzer, and Amazon Pay. A special feature: Customizable shipping, payment, and trusted icons in your own corporate identity style! A live demo is available at magento2-shop.de . Also available for the backend.

Weaknesses – to be honest: Storetown Media is a (still) small provider with a correspondingly smaller public review base than Amasty or Mageplaza. Those who consider hundreds of marketplace reviews or a large ecosystem of dozens of add-on modules from the same manufacturer as a deciding factor will find these more readily available from the larger competitors. The documentation is also more concise than that of providers with their own knowledge base portals. However: with us, you receive German-language support, an integrated "cancellation button form," and GDPR-compliant functionalities, which are essential for the DACH region (Germany, Austria, and Switzerland). The choice is yours.

Amasty One Step Checkout – large ecosystem, subscription model

Amasty is one of the best-known Magento extension developers. The One Step Checkout is available in three editions: $149, Pro $289, and Premium $849; each includes 12 months of updates and support, after which an annual renewal fee starting at $175 applies (as of July 2026, according to the provider's website ^[1] ).

Strengths: Very extensive feature set in the higher editions (delivery date selection, gift wrapping, custom fields, etc.), a 4,9-star rating displayed on the product page based on 62 reviews, GraphQL support, and ADA/WCAG compliance for Luma and Hyvä. Amasty has announced a “Hyvä-First” strategy for its entire portfolio in 2026 ^[6].

Please note: The licensing model is a subscription – those who want updates and support beyond the first year pay continuously. For the Pro edition, some Hyvä compatibility is provided via additional Composer packages, which require an active subscription ^[4] . Support in German is not offered. The currently listed compatible versions start with Magento 2.4.5 – older 2.3/2.4 shops should check compatibility before purchasing.

OneStepCheckout.com – the classic with a premium price

OneStepCheckout.com is one of the oldest providers in this segment and lists over 20.000 Magento merchants as its customer base on its website ^[5] . The Community license for Magento 2 costs €485, and the Enterprise license €1.685 – both as one-time licenses. Support and update plans are sold separately (€120 for 12 months), as are installation (€70) and additional domains (€75) ^[2].

Strengths: Long market history, large installed base, focus on a single product. According to the provider, they will refund the purchase price if the software cannot be made to run despite support assistance ^[2].

Please note: With a starting price of €485 plus a separately charged update plan, this is the most expensive solution in this comparison. The order page provides no information regarding Hyvä compatibility, layout options, or an EU right of withdrawal button (as of July 2026); anyone requiring any of these features should inquire with the provider before purchasing. German-language support is not offered.

Mageplaza One Step Checkout – large review base, 60-day money-back guarantee

Mageplaza's One Step Checkout starts at $199 (Standard Edition) as a one-time payment, including one year of updates and support; higher editions with more features are available. The product page lists 227 reviews with an average rating of 5,0 and a 60-day money-back guarantee ^[3].

Strengths: Attractive entry price, the longest money-back guarantee in comparison, the largest number of reported reviews, and, according to the provider, Hyvä theme compatibility including free on-demand compatibility for Hyvä Checkout. Magento versions 2.4.4 to 2.4.9 (Open Source, Commerce, and Cloud) are supported.

Please note: Hyvä Checkout compatibility is provided "on demand" and may therefore require an additional coordination step. Shops on Magento 2.3.x are not compatible. An EU right of withdrawal button is not mentioned on the product page (as of July 2026), and support in German is not offered.

Which extension is right for whom?

Scenario 1 – DACH retailers with EU end customers: If German-speaking support is important and the EU cancellation button required since June 19, 2026, needs to be covered without additional development, then the STM Smart One Page Checkout is the obvious choice – it is the only solution in the comparison that offers both.

Scenario 2 – Feature maximizer with a running budget: If you want as many checkout features as possible (delivery dates, gift options, custom fields) from one source and are prepared to pay an annual subscription starting at $175, Amasty (Pro/Premium) is a good choice.

Scenario 3 – Budget-oriented international shop: For English-speaking teams with Magento ≥ 2.4.4 who are looking for the lowest entry price and the longest money-back guarantee, Mageplaza (from $199, 60 days) is worth considering.

Scenario 4 – Hyvä migration planned or mixed operation: Shops currently running on Luma and planning to switch to Hyvä in the medium term benefit from the native dual support of the STM Smart One Page Checkout – one purchase covers both frontends without compatibility packages or on-demand requests.

FAQ

What is the best alternative to Amasty One Step Checkout?

It depends on the criteria: Those who prefer a one-time payment with optional, discounted renewal instead of a subscription (renewal starts at $175/year with Amasty) and require German support will find an alternative in STM Smart One Page Checkout (€249). Those primarily concerned with price can compare Mageplaza (starting at $199); those seeking extensive market history should consider OneStepCheckout.com.

Which Magento Checkout Extension is Hyvä-compatible?

Three of the four extensions compared show Hyvä compatibility: STM Smart One Page Checkout (native, Hyvä and Luma in the same package), Amasty ("Hyvä-ready," with the Pro edition sometimes requiring additional compatibility packs), and Mageplaza (Hyvä theme compatible, Hyvä checkout compatibility available upon request). OneStepCheckout.com makes no mention of this on its order page (as of July 2026).

Which one-page checkout extension complies with the EU's mandatory cancellation button requirement from June 2026?

Since June 19, 2026, EU consumer rights regulations require an easily accessible cancellation button in online retail. Of the four extensions compared, only STM Smart One Page Checkout currently features an integrated EU cancellation button; Amasty, OneStepCheckout.com, and Mageplaza do not provide this information on their product pages (as of July 2026) – it is advisable to inquire before purchasing.

One-time payment or subscription – what is common with Magento checkout extensions?

Both models exist on the market: Amasty uses a subscription model (12 months included, then annual renewal), OneStepCheckout.com offers a one-time license with separately sold update plans, and Mageplaza and STM offer a one-time payment with one year of included updates. The timeframe is crucial for the total cost: Over three years, the models can differ significantly – a separate total cost comparison is worthwhile.

Conclusion & next step

All four extensions reduce the Magento 2 checkout to a single page – the differences lie in the licensing model, the hygiene strategy, support, and EU compliance. If you're looking for a checkout with a one-time payment (€249), 12 months of updates and support, native hygiene and Luma support, four switchable layouts, an integrated EU cancellation button, and German support: Try the STM Smart One Page Checkout – risk-free with a 30-day money-back guarantee. A live demo is available at magento2-shop.de.
