Headless Frontend Options for SAP Commerce Cloud Compared

Teams modernizing an SAP Commerce Cloud storefront face a clear fork: stay on the SAP Composable Storefront (formerly Spartacus), build a fully custom frontend on the OCC API, or put a Frontend Management Platform (FMP) like Laioutr on top. This article compares all three directly, without glossing over the trade-offs.

The starting point: SAP Commerce Cloud is already API-first

SAP Commerce Cloud, with its Hybris heritage, is a Java-based enterprise commerce platform. Since the move to a decoupled architecture, the storefront talks to the backend exclusively through the OCC REST API (Omni Commerce Connect): product search, cart, checkout and customer account. That API is technology-agnostic, so the frontend question is genuinely open. The backend stays put. The decision is which frontend layer is the best investment.

Option 1: SAP Composable Storefront (Spartacus)

The Composable Storefront is SAP's own Angular-based, open-source headless storefront. It ships with SSR for SEO, PWA capabilities and CMS-driven page composition.

It is the natural default if you have an Angular engineering team. The trade-off: every customization beyond the defaults is Angular development, and you own the upgrade treadmill, hosting, performance budget and accessibility work yourself.

Option 2: Custom build on the OCC API

A custom frontend in React, Vue or Next.js gives maximum control. The OCC API is well documented and framework-agnostic, so this is feasible.

The cost is a multi-month build, a dedicated frontend team and permanent ownership of everything: hosting, CI/CD, dependency upgrades, Core Web Vitals and accessibility compliance. Sensible only when frontend engineering is a strategic core capability.

Option 3: Laioutr FMP on the OCC API

Laioutr sits as a frontend layer on the existing OCC API. The SAP backend stays untouched. You get a visual editor, more than 70 prebuilt commerce components, EU hosting and a Lighthouse 100 performance target.

The advantage is predictability and speed: no multi-month greenfield, no framework maintenance, and marketing teams can compose landing pages and campaigns without engineering tickets. WCAG 3.0 and BFSG are part of the platform baseline, not a separate audit.

Side-by-side

• Time-to-launch: Composable Storefront = months of Angular work; Custom build = several months; Laioutr = weeks
• Year-1 TCO: Composable Storefront = engineering-heavy; Custom build = high; Laioutr = predictable subscription
• Maintenance: Composable Storefront and Custom = your team; Laioutr = platform-operated
• Accessibility: Composable Storefront and Custom = your responsibility; Laioutr = WCAG 3.0 and BFSG in the standard
• Backend optionality: Custom = locked to OCC; Laioutr = backend-agnostic across SAP, commercetools, Shopify and more

When each option wins

Composable Storefront or a custom build wins when you have a strong Angular or JavaScript team and pixel-level control is a strategic priority. Laioutr wins when you want weeks to go-live, marketing autonomy, built-in EU compliance and the freedom to keep backend options open.

FAQ

Does Laioutr replace the Composable Storefront?

It is an alternative frontend layer on the same OCC API. You can keep the Composable Storefront, or use Laioutr instead for faster time-to-launch and no-code page composition.

Does the SAP backend change?

No. Laioutr consumes the OCC REST API. Catalog, pricing, promotions and checkout logic stay in SAP Commerce Cloud.

How does pricing compare to a custom build?

Total cost of ownership is typically lower because hosting, components and the editor are included, and no separate frontend team is required. See pricing or book a strategy call.
