Headless WordPress
Headless WordPress keeps the editor your team is comfortable with and swaps the ageing front end for a fast, modern one built in Next.js — the best of both.

What Headless WordPress is
In a headless setup, WordPress stays as the content back end and editing experience, but the public site is a decoupled front end that pulls content over the REST or GraphQL API. The theme layer is gone; rendering happens in a framework like Next.js.
Editor & developer experience
For editors, nothing changes — and that is the entire pitch. The team keeps the WordPress admin they already know, with the same posts, pages, custom fields and workflow. No migration of content, no retraining, no new tool to learn. The only difference they notice is that the public site is suddenly much faster.
For developers, the theme layer disappears. WordPress becomes a pure content back end, and the front end is rebuilt in Next.js, pulling content over the REST or WPGraphQL API and rendering it statically at the edge. That split is where the performance and security gains come from — the public site no longer runs PHP or exposes the admin to visitors — but it does mean two systems to run rather than one, which is a deliberate trade, not a free upgrade.
Where it earns the shortlist
Headless WordPress earns the shortlist when a business is genuinely invested in WordPress content and workflows but has outgrown the front end. It is the upgrade path that keeps the editor and the content while delivering a fast, edge-rendered site with a far better security posture — no re-platforming, no retraining. Reach for it to modernise an existing WordPress estate, not to start a greenfield project.
- Businesses with existing WordPress content that need a faster front end
- Teams that want to keep the WordPress admin but drop the theme layer
- Sites where performance and security need to step up without re-platforming
When teams choose it — and when they don’t
Choose Headless WordPress when
You are committed to WordPress content
Years of posts, pages and editorial habit worth keeping intact.
The front end has to get faster
A statically rendered, edge-delivered Next.js site lifts performance scores sharply.
Security needs to step up
The public site no longer exposes the WordPress admin or theme layer to visitors.
You cannot afford to re-platform
Keep the editor and content while replacing only the front end.
Look elsewhere when
It is a greenfield build
With no WordPress commitment, Sanity plus Next.js is a cleaner starting point.
You want the fewest moving parts
Two systems add operational overhead; a single custom WordPress build may be simpler.
The team edits visually
If marketers want drag-and-drop page composition, Storyblok fits better.
Pricing, in plain terms
Costs sit a step above a standard WordPress build, because you are running two things: the WordPress back end (still hosted and maintained) and a Next.js front end deployed to the edge, typically on Vercel. In return you drop a lot of front-end plugin and performance-tuning cost. We host and manage both layers on a recurring plan, and scope the front-end build within our project ranges up front.
The SmartaStudio take
Headless WordPress is the answer to a very specific problem: “we love our WordPress content and workflow, we just hate how slow and dated the site feels.” Keep the editor, replace the front end with Next.js, and the site gets dramatically faster and safer without anyone relearning anything. The honest caveat is that you are now running two systems, so it only pays off when the performance and security gains justify the extra moving parts. Starting fresh with no WordPress baggage? We would build on Sanity and Next.js instead.
