Frontend-as-a-service (FaaS)

Frontend-as-a-service (FaaS) is a productized delivery model for the storefront layer of a headless commerce project. Instead of building a custom storefront from scratch, the merchant licenses a pre-built, production-ready frontend and customizes it for their brand. The provider maintains the underlying codebase as a product. A FaaS product ships the pages every ecommerce site needs — home, category, product detail, cart, checkout, search, account — along with a CMS, pre-wired integrations for payment, shipping, search, and CRM, and the server-side rendering and structured data needed for SEO. The merchant pays a subscription for the license and runs a fixed-scope setup project to connect the backend, apply branding, and go live. ## How FaaS differs from other delivery models FaaS sits between a platform theme and a fully custom headless build. A theme is constrained by what the commerce platform's frontend engine allows. A fully custom build gives complete freedom but requires a team to build and maintain the storefront from scratch. FaaS reduces build time and shifts long-term maintenance to the provider, at the cost of working within a productized frontend's constraints. A typical fully custom headless build takes 4 to 9 months. A FaaS project typically launches in 6 to 12 weeks because the storefront, backend-for-frontend (BFF) layer, and most integrations are already in place. ## What FaaS is not FaaS is not a website builder. The storefront is a production-grade software application built in a JavaScript framework like Nuxt or Next.js. Developers configure and extend it. Editors manage content through the CMS. FaaS is not a commerce platform. It does not own products, pricing, inventory, or orders. Those stay in the commerce backend — Norce, Shopware, Shopify, Magento, or another API-first engine. FaaS is the frontend that connects to the backend. ## How Frntkey relates Frntkey is a frontend-as-a-service for Norce Commerce and Shopware. The storefront is built on Nuxt.js, Vue.js, and Tailwind CSS. Storyblok ships bundled as the CMS. Hosting runs on Vercel. The full integration set — Klarna, Walley, Voyado, Hello Retail, Lipscore, Ingrid — is pre-wired and ready to activate per project.
