Scayle alternative for teams keeping their existing backend

What Scayle is

Scayle is an enterprise B2C commerce engine, based in Hamburg. It was originally the technology behind ABOUT YOU, the European fashion retailer, and was spun out into a separate subsidiary (SCAYLE GmbH) in August 2023. Since 2025, ABOUT YOU Group has been part of Zalando Group, which puts Scayle inside the Zalando umbrella.

The product is a full commerce engine, not just a frontend. The SCAYLE Commerce Engine ships with PIM, Shop Management, Checkout, OMS, and an extensive feature set out of the box. SCAYLE Payments is a separate product line. The platform powers brands and retailers including DEICHMANN, Marc O'Polo, FC Bayern, DEPOT, Fielmann, Harrods, and Manchester United, across around 300 online stores in European markets. Scayle was listed as a Challenger in the 2025 Gartner Magic Quadrant for Digital Commerce.

On the storefront side, Scayle ships an open-source Nuxt and Vue 3 starter kit — Storefront Core and a Storefront Application — that connects to the Scayle Commerce Engine. Merchants on Scayle typically build on this Storefront kit, or connect their own frontend through Scayle's APIs.

Where Frntkey differs

Frntkey is a frontend-as-a-service, not a commerce platform. The two products operate at different layers of the stack, so the honest comparison starts with that distinction.

• Category. Scayle is a full commerce engine plus an optional Nuxt-based Storefront. Frntkey is a productized frontend that connects to commerce backends you already have. If you are evaluating Scayle, you are picking a new commerce platform. If you are evaluating Frntkey, you are keeping your existing backend.
• Backend support. Scayle runs on the Scayle Commerce Engine. Frntkey runs on Norce (native) and Shopware, with other API-first commerce engines supported on a project basis.
• Frontend stack. Both Scayle Storefront and Frntkey are built on Nuxt and Vue 3. The framework choice is the same. The platform underneath is what differs.
• Customer segment. Scayle's base is enterprise B2C fashion and retail. Frntkey's base is mid-market Nordic B2B and D2C merchants, with native integrations for Klarna, Walley, Vipps, Voyado, Hello Retail, Lipscore, and Storyblok.
• Bundled CMS. Frntkey includes Storyblok with ready-made blocks, multi-language support, and time-controlled content. Scayle does not bundle a CMS.
• Delivery model. Scayle is delivered through Scayle's solution partner network. Frntkey is delivered with implementation by Nordic Web Team, a Stockholm-based agency.

Side-by-side comparison

When Scayle is the right pick

Scayle is the better fit when:

• You are re-platforming the commerce backend and want an enterprise B2C engine with PIM, OMS, and Shop Management included.
• Your business is fashion, retail, or another vertical close to Scayle's existing customer base.
• Annual GMV and infrastructure expectations match an enterprise license model.
• You want a single vendor relationship for backend, frontend kit, payments, and operational tooling.

If those apply, Scayle is a serious answer. The platform powers ABOUT YOU itself, which is a credible enterprise proof point.

When Frntkey is the right pick

Frntkey is the better fit when:

• The backend is Norce or Shopware, and you do not want to replace it.
• The frontend is the bottleneck and the rest of the stack is staying.
• The buyer profile is Nordic B2B or D2C, with Klarna, Walley, Vipps, and Voyado as core integrations.
• You want a productized frontend with implementation by a Nordic agency, not an enterprise platform contract.
• Project size and timeline fit a mid-market scope rather than an enterprise re-platforming program.

The honest summary

Scayle and Frntkey are not direct competitors in most evaluations. Scayle is a commerce platform decision. Frntkey is a frontend decision. The buying motion, the budget, and the timeline are different.

If you are re-platforming the commerce backend, talk to Scayle (and to Norce, Shopware, and commercetools while you are at it). If you are keeping your existing backend and only modernizing the frontend, talk to the Frntkey team.
