“Headless” WordPress means using WordPress only to manage content, and building the public website separately — commonly with Next.js — which fetches that content through an API. Editors keep the familiar WordPress admin; visitors get a fast, modern front end. This website is built that way. Here is an honest look at when the approach makes sense.
How a headless setup works
- WordPress stores pages, posts, products, and custom content, with fields defined for each content type.
- An API layer — usually WPGraphQL or the WordPress REST API — exposes that content.
- A Next.js application fetches the content and renders pages, either ahead of time (static generation) or on request, with caching in between.
The benefits
- Performance. Pages can be pre-rendered and served from a CDN, which makes good Core Web Vitals scores much easier to achieve than with a heavy theme and many plugins.
- Design freedom. The front end is not constrained by a theme or page builder, so complex layouts, animations, and interactions are straightforward.
- Security. The WordPress admin can sit on a separate subdomain, out of the visitor’s path, reducing the attack surface of the public site.
- Reuse. The same content API can feed a mobile app, a kiosk, or a partner integration.
- Structured content. Content is modelled as fields rather than free-form page-builder blocks, which keeps it consistent and easier to reuse — and easier for search engines and AI systems to understand.
The costs
- Two systems to host and maintain. WordPress needs PHP hosting; Next.js needs a Node.js-capable platform. Both need updates.
- Developer involvement for layout changes. Editors can change content in defined fields, but new page layouts are built in code. Some teams miss drag-and-drop page building.
- Plugin limitations. Many WordPress plugins assume they control the front end. Forms, SEO tools, and e-commerce extensions may need API-aware alternatives or custom work.
- Preview takes setup. Seeing a draft exactly as it will appear requires configuring preview mode.
When headless is worth it
- Performance and SEO are business-critical — for example, large content or location-led sites.
- You need a distinctive design or interactive features a theme cannot deliver well.
- Content must be reused across several channels.
- You have, or will retain, development support for the front end.
When a traditional WordPress site is the better choice
- A small business site where editors want full control of layouts without a developer.
- Budgets that cannot support two hosting platforms and ongoing development.
- Sites that depend heavily on plugins that only work with traditional themes.
A well-built traditional WordPress site — light theme, few plugins, good hosting, image optimisation — can still perform very well. Headless is a tool, not an upgrade every site needs.
Practical tips if you go headless
- Model content with structured fields from the start, and keep editor instructions next to each field.
- Plan caching and revalidation so content changes appear quickly without rebuilding the whole site.
- Make the front end resilient: if the CMS is briefly unreachable, pages should still be served from cache.
- Set up previews, redirects, sitemaps, and structured data on the front end — they no longer come from WordPress plugins automatically.
- Keep the WordPress admin on its own subdomain with strong authentication.
