Headless CMS migration consultants and development Australia

What is a headless CMS?

A headless CMS stores content and nothing else. It delivers that content through an API. A separate front end decides how it looks.

What is the difference between a CMS and a headless CMS?

A traditional CMS stores content and builds the web page from it. A headless CMS stores content and leaves the page to another application. One content store can then feed a website, an app and a kiosk.

What are examples of headless CMS platforms?

Contentful, Storyblok, Sanity, Strapi and Payload are built as headless platforms. Statamic and Craft CMS can run headless. WordPress and Adobe Experience Manager can serve content through an API too.

What are the disadvantages of a headless CMS?

A headless CMS costs more to build than a single template site. The front end is a separate application that someone must build and run. Editors lose the drag-and-drop page builder, and the team must build a preview. Each connected service adds integration work.

Content modelling also takes longer than the API work. A site with one editing team and one channel often does not need any of this.

What a headless CMS actually changes

A traditional CMS bundles two jobs into one system: it stores content and decides how that content looks on a page. A headless CMS splits those jobs apart. Content sits in a structured store (a product description, an article body, a set of image references) and gets delivered through an API to whatever needs it: a Next.js website, an iOS app, a kiosk in a retail store, a partner's booking widget. The front end owns the rendering; the CMS owns the content.

That split matters most once a business publishes to more than one channel from the same source. A retailer pushing product copy to a website, an app and a marketplace feed used to maintain three versions or accept drift between them. With structured content delivery feeding all three from one model, an editor updates a price or a description once and every channel picks it up on its next fetch.

The cost lands on marketing: a headless CMS usually removes the visual, drag-and-drop page builder that marketing teams are used to. Content editors work in structured fields, which asks for different authoring habits than a WYSIWYG canvas, and someone has to build the preview tooling that shows what a change will look like before it goes live. Teams that skip this step tend to find publishing confidence drops in the first few months, even though the technical migration went smoothly.

Headless CMS vs WordPress, AEM and traditional platforms

WordPress can run headless: its REST API will serve JSON to a React front end without much trouble, but doing so gives up the theme layer and a large share of the plugin ecosystem WordPress built its reputation on. Teams considering this route are often better served by a purpose-built headless platform (Contentful, Sanity and Strapi all fit the brief) unless there's a specific reason to keep WordPress's authoring interface. The WordPress to headless migration path is well trodden, but the content model rework usually takes longer than the API swap.

Adobe Experience Manager occupies different territory. AEM can be deployed headless, exposing content through its Content Fragment API, and for organisations already running AEM for personalisation, DAM and multi-brand workflow, that's a sound way to extend an existing investment. For a business that doesn't already run AEM, adopting it purely as a headless content API means taking on a full digital experience platform, so it is worth comparing against a purpose-built headless CMS such as Contentful or Sanity on cost, footprint and implementation effort for that specific case. If the organisation already relies on other parts of the AEM stack, that existing investment is usually the deciding factor.

Shopify sits in a narrower lane: its Storefront API supports headless commerce front ends, which suits retailers wanting a custom checkout or app experience without leaving Shopify's back end. It isn't a general-purpose content platform, so teams publishing a lot of editorial content alongside product data usually pair it with a dedicated headless CMS.

Choosing a headless CMS platform for React and Next.js

Most headless CMS platforms (Contentful, Sanity, Strapi, Storyblok, Craft CMS in headless mode) serve content to a React or Next.js front end without friction; the API layer is rarely the differentiator. What separates them in practice is editorial experience (whether a non-technical marketer gets a usable preview and a sane approval flow), content modelling flexibility, and how the platform handles localisation and role-based access as the team grows. A business publishing to one market with a small content team can move fast on almost any of them. One publishing across states, brands or languages should weight the evaluation toward editorial approval automation and permissioning before comparing API response times.

Personalisation is the other place platforms genuinely diverge. Some headless CMS products ship native audience segmentation and staged content delivery; others expect that logic to live in the front end or a separate service. Teams planning content personalisation work should confirm which side of that line their shortlisted platform sits on before committing, because retrofitting personalisation into a content model that wasn't built for it is a slower job than building it in from the start.

When a headless CMS is the wrong call

A single-site brochure business with one content editor and no plan to add a second channel rarely needs the added engineering overhead of a headless architecture; a well-run WordPress site or a hosted builder does that job for less. The decision to go headless earns its cost when there's a genuine second or third consumer of the same content: an app, a partner feed, a franchise network, a set of regional microsites. The NRMA Parks and Resorts migration from WordPress to a headless CMS shows the pattern clearly: the trigger wasn't a desire for modern architecture, it was multiple properties needing to draw from consistent, centrally managed content.

The most underestimated part of any headless CMS project is the content model design and the migration of legacy content into it. API integration is usually straightforward by comparison. Free-text WordPress pages don't map cleanly to structured fields, and teams that rush this step end up with a content model that looks tidy in a diagram but doesn't match how editors actually work day to day.

Headless CMS or WordPress: which suits a mid-sized Australian business website better?

WordPress suits a single website with one editing team and no second channel. It is quick to run and cheap to keep. A headless CMS suits a business that publishes the same content to a website and an app, or to several brands. It also suits a team whose plugin stack slows every release.

WordPress can also stay as the editing tool and serve content through its API. The choice depends on the publishing model, the team and the channels. It does not depend on which option is newer.

Who can advise on Adobe Experience Manager or a composable headless stack and build either?

Choose a firm with no product of its own to sell. Ask it to compare the two on authoring experience, integrations, hosting and the cost of owning each.

National Digital advises on that choice and builds the composable option, including on Contentful. It does not sell a CMS or resell licences. Adobe Experience Manager is the sound answer for an organisation that already runs its personalisation and asset management.
