What is a Headless CMS?

Key takeaways

1. A headless CMS stores content as structured data (JSON) and delivers it to any frontend through an API, rather than publishing fixed HTML pages to a single website.

2. The “head“ is the frontend. Decoupling it from the “body“, the backend repository, lets one content repository serve a website, a mobile app, an in-store kiosk, digital signage and a social commerce feed at the same time.

3. Headless is the architecture. Composable is the strategy of selecting best-of-breed components. Headless is what makes composable commerce possible.

4. Agentic AI needs structured content. Monolithic systems store content as flat HTML, which agents cannot reliably read, generate against or publish into.

5. Generic headless platforms store content well but leave merchandising teams working in forms with no visual preview. Retail-centric headless platforms keep the decoupled architecture and add visual authoring, scheduling and retail content models.

For enterprise retail the question is no longer whether to go headless, but whether the headless platform you choose understands retail.

The era of the “all-in-one“ website builder is over. To keep pace with consumer expectations, brands are decoupling their content from their code. Let’s explore how headless CMS architecture works, why it is replacing traditional systems, and how it lays the foundation for an automated content supply chain.

Headless vs. traditional CMS

To understand the future, you have to look at the limitations of the past. While monolithic systems were built for single websites, headless systems are built for the omnichannel world.

Headless vs hybrid CMS. What is the difference?

A hybrid CMS can publish in two ways. It renders web pages itself, as a traditional CMS does, and it also delivers content through APIs to apps, screens and other channels. A headless CMS has no presentation layer of its own, so every channel gets its content by API. The difference shows when you reuse content. In a hybrid system, content written inside page templates often has to be rebuilt for another channel. In a headless system, every item is already structured data that any front end can request.

Our view, set out in February 2024 in It’s either a headless CMS or it isn’t, is that most products sold as hybrid began as page-based systems and added APIs later. Separating the two layers after years of coupled code is hard, and the page model tends to win.

The MACH Alliance offers a practical test. Its members must be microservices-based, API-first, cloud-native and headless. Amplience is a MACH Alliance-certified member.

Headless CMS vs DXP

A headless CMS stores structured content and delivers it by API. A digital experience platform (DXP) adds experience orchestration, personalization, analytics and business workflows on top of that delivery. Some DXPs are monolithic suites from one vendor. Others are composable stacks, where a headless CMS is the content layer and connects by API to search, personalization and commerce tools.

How does a headless CMS support omnichannel retail?

In an omnichannel setup, each piece of content is stored once as structured data and requested by every channel through an API. A campaign banner, product story or promotion isn’t tied to one page template. The website, the app and the screens in your stores each ask for the same content item and render it in their own way. When the team updates that item, every channel picks up the change on its next request.

Worked example. One weekend sale, three channels

A retailer is launching a weekend sale and wants the same message on its website, in its app and on the screens in its stores.

1. Create once. A merchandiser builds a single campaign banner content item, with a headline, a call to action, a link to the sale category and a hero image from the DAM.

2. Preview and schedule. She previews the banner on mobile, tablet and desktop, then schedules it for Friday morning.

3. Localize. Regional teams add locale variants inside the same content item. Each market’s API call returns its own variant.

4. Deliver. At go-live each channel requests the same item. The website shows it as a home page banner, the app as a native card and the store screens full-screen in landscape.

5. Fit the image to each screen. Dynamic Media generates the crop, size and format each device needs from the one master image, and focal point detection keeps the product in frame.

6. Change once. On Saturday the discount goes up. The merchandiser edits one field, and all three channels show the new offer with no code deploy.

In practice. Traeger Grills went from publishing twice a month to publishing daily across its website and mobile app.

Headless CMS vs DAM. Do you need both?

A headless CMS manages structured content such as product descriptions, editorial copy and page layouts, and delivers it by API. A digital asset management (DAM) system manages rich media, including product images, video, banners and brand files. Retailers usually run both, because almost every page combines copy with media. So the choice that matters is how they connect. They can be separate products joined by an integration, or one platform with shared workflows.

When separate systems cost more. A separate CMS, DAM and image service means three contracts and three integrations to maintain, with media transformation logic split across systems.

How Amplience handles it. Amplience CMS and Amplience DAM are part of one content operations platform, so teams manage copy and assets in the same workflows. Teams upload one master asset, and Dynamic Media generates the optimized variants each channel needs. Each product can be licensed on its own or deployed together.

See the DAM in Amplience digital asset management.

What are the drawbacks of a headless CMS?

Headless puts more work on your side of the API. There is no built-in front end, so someone has to build and run every website, app and screen that shows your content. Year-one costs usually run higher than a coupled website, because the front-end build sits on top of the platform license. Editing experience also varies between platforms. For a retailer publishing to several channels at scale, these costs pay back. For a small, single-channel estate they may not.

The AI section above still applies. If agents will read and write your content, structured content is the foundation. The trade-offs below are about cost and capability, and they apply to any headless platform.

• You need front-end capacity. Developers, architects and project managers, in-house or through a systems integrator, build and maintain each front end.

• Year one costs more. Implementation covers content modeling, front-end builds and integrations, on top of the license. The saving comes later, from faster changes and reuse across channels.

• Suite-first organisations may prefer to stay put. Teams committed to one vendor’s full suite, and building page-based websites only, may get more from that suite.

• Editing experience varies. Some headless platforms give marketers a full visual preview, while others rely mainly on forms. Test the editor with your own merchandisers before you choose.

Which headless CMS is best for enterprise retail?

Enterprise retail has different requirements from a SaaS startup or a media publisher. Choosing the wrong headless CMS creates the same bottlenecks you were trying to escape. Here is how to evaluate the market.

Which commerce platforms does Amplience integrate with?

Amplience integrates with Salesforce Commerce Cloud, SAP Commerce Cloud, commercetools, Shopify, BigCommerce and SCAYLE. Most of these integrations let content teams pull product and category data from the commerce platform into the CMS while they build content, and the content then reaches the storefront by API. The SAP integration works differently. It displays product media from Dynamic Media in SAP Commerce Cloud storefronts. Each platform has its own page with the detail.

For commercetools, Shopify, BigCommerce and SAP, the eComm Toolkit extension brings core commerce information into Amplience, so editors stop switching between platforms. See every integration, extension and front end in the Amplience Marketplace.

What does a headless CMS cost?

A headless CMS has two cost lines, the platform license and the implementation. Vendor-supported platforms charge a subscription, usually on an annual or multi-year contract. The price is typically set by usage, such as traffic, content volume or API calls, and often by users, locales or environments too. Open-source options have no license fee for the core product, but you pay for hosting, support and maintenance. Implementation covers content modeling, front-end builds and integrations.

Common pricing models

What drives the total cost

• Usage basis. Traffic, content volume, API calls, media delivery, seats or locales, depending on the vendor.

• Scope. How many brands, sites, markets and teams the platform serves.

• Add-on products. Whether DAM, image delivery, personalization or AI automation are included or licensed separately.

• Implementation approach. Your own team, a systems integrator or a blend of both. Integrators commonly charge on time and resources or a fixed price.

• Running costs. Front-end hosting, ongoing development and support after go-live.
