Headless WordPress & React Development
KlyDexa builds headless WordPress applications using React and Next.js, decoupling WordPress’s content management from a fully custom frontend. This gives businesses WordPress’s editing simplicity with the speed and flexibility of a modern JavaScript frontend.
- WordPress as headless CMS via REST API / WPGraphQL
- React and Next.js frontend development
- Faster load times and full design freedom vs. traditional WP themes
- Best for content-heavy sites needing app-like interactivity

What does a headless WordPress build involve?
WordPress becomes a pure content backend while a custom React frontend handles everything visitors see. Here is what that covers.
Headless Architecture Setup
WordPress configured as a pure content backend (REST API or WPGraphQL).
React/Next.js Frontend Build
Custom frontend decoupled from WordPress's rendering.
Content Modeling
Structuring WordPress content types for clean API consumption.
Performance Engineering
Static generation, caching, and CDN delivery for near-instant load times.
Editor Experience
Keeping WordPress's familiar editing UI for content teams despite the decoupled frontend.
API Security
Authentication and rate-limiting for headless endpoints.
The two questions everyone asks first
How much does a headless WordPress build cost?
Higher than a traditional WordPress site due to separate frontend/backend development, scoped individually based on frontend complexity.
How long does it take?
Typically 8-16 weeks depending on frontend complexity and number of content types.
Two stacks, one process
Headless projects have more moving parts than a standard WordPress build, so we keep the process tight. Here’s how a project runs from first conversation to live site.
Discovery & Content Modeling
We map your content types, fields, and relationships before any code gets written. Headless projects live or die on this step, since a messy content structure becomes a messy API.
API & Architecture planning
Backend & Frontend Development
WordPress is configured as a pure content backend while the React/Next.js frontend is built against it. Running both in parallel means the frontend always has real content and real endpoints to work with.
QA & Performance Testing
Cross-browser and responsive testing, plus the checks specific to headless: API response times, build times, cache behaviour, and Core Web Vitals on the live frontend.
Launch
Deployment of both the frontend and the WordPress backend, DNS and CDN configuration, and monitoring through the first weeks of real traffic.
Support
Optional maintenance covering both halves of the stack. Headless sites have two things to keep updated instead of one, which is worth planning for rather than discovering later.
Traditional WordPress vs. headless
Headless isn’t automatically better, it’s better for certain problems. Here’s where each approach actually wins.
| Traditional WordPress | Headless WordPress & React | |
|---|---|---|
| Load speed | Good with caching, but every page is rendered by PHP at request time | ✓ Pre-built pages served from a CDN, with no server render per visit |
| Design flexibility | Constrained by the theme and page builder you work within | ✓ Custom-built frontend, so the design isn't fighting a theme |
| Editor experience | Live preview, page builders, and instant publishing | Familiar admin, but preview and publishing are less immediate |
| Hosting complexity | One environment, one deployment, standard WordPress hosting | Two environments to host and maintain, with higher running costs |
| Best-fit use case | Marketing sites, blogs, and stores edited daily by the content team | ✓ Content-heavy sites needing app-like interactivity or multi-channel delivery |
Headless is easy to get wrong. We've done it right
React and WordPress, not one or the other
We build the Next.js frontend and configure the WordPress backend ourselves, so nothing gets lost in the handoff between two separate teams.
Performance is the starting point
Static generation, caching strategy, and CDN delivery are decided in week one, not bolted on after the site turns out slow.
Your editors keep the admin they know
Content teams carry on working in the WordPress dashboard they already use. The frontend changes completely; their day-to-day doesn't.
Built for traffic spikes, not just launch day
Pre-rendered pages on a CDN hold up under load, which matters for content-heavy sites where a single popular page can carry the traffic.

What is headless WordPress and how is it different from a normal WordPress site?
In a normal WordPress site, WordPress stores your content and renders the pages visitors see. In a headless setup, WordPress only stores and serves the content through an API, while a separate frontend built in React or Next.js handles everything visitors actually see. The editing side stays WordPress; the display side becomes a custom application.
Why would I need React instead of a standard WordPress theme?
You usually don’t, and we’ll say so if that’s the case. React makes sense when you need app-like interactivity, a design a theme can’t accommodate, or the same content feeding a website plus a mobile app or other channels. If you need a fast, well-built marketing site, a properly optimised traditional WordPress build is simpler and cheaper.
Can my content team still use the normal WordPress editor?
Yes. They log into the same WordPress dashboard and edit content the way they always have. The main difference is preview and publishing: because the frontend is separate, changes may take a build cycle to appear rather than showing instantly. We configure preview so it’s as close to the normal experience as the architecture allows.
Is a headless WordPress site more expensive to maintain?
Generally yes. You’re hosting and updating two things instead of one, and frontend dependencies need their own maintenance cycle. That’s a real ongoing cost worth budgeting for, and it’s a reason we don’t recommend headless unless the performance or flexibility benefits justify it.
What kind of businesses benefit most from headless WordPress?
Content-heavy publishers, businesses with high traffic where CDN delivery meaningfully cuts costs, companies needing app-like interactivity, and teams feeding one content source into multiple channels. Businesses whose main need is a marketing site edited daily usually get more value from traditional WordPress.
