Headless WordPress Development

Headless WordPress development: WordPress as a content backend, a frontend in whatever stack actually fits -- Hugo, Astro, Next.js, Nuxt, or vanilla JavaScript -- and the REST API work that connects them. From a principal engineer with 14 years in WordPress.

Sub-Second Load Times

Static HTML at build time, with no client runtime required to render a page and no database query on every request.

REST API Backends

WordPress's REST API shaped with custom fields, custom endpoints, and a real auth strategy for anything beyond public content.

Multi-Tenant Architecture

One WordPress backend serving multiple sites, each with its own frontend and its own scoped search, without multiplying infrastructure.

WordPress Stays the Editor

Content teams keep the WordPress admin they already know. The frontend rebuilds automatically when content changes.

WordPress as the backend. Something faster as the frontend.

Headless WordPress means using WordPress purely as a content backend, exposed through its REST API, while a separate system builds and serves the actual frontend. It is worth it when performance, security, or scale matter more than the convenience of WordPress’s own templating and page builders, and it costs real engineering effort that a standard WordPress site with good caching doesn’t need. For the honest tradeoff, see 84EM’s headless WordPress guide.

84EM runs headless WordPress in production, including a multi-tenant directory platform built on Hugo serving multiple niche directories off one shared backend. WordPress stays the editor. The frontend gets chosen per project based on traffic and performance needs, from Hugo, Astro, Next.js, Nuxt, or vanilla JavaScript.

Who actually builds your headless project?

One principal engineer, start to finish. The same person shapes the REST API, builds the frontend, and owns the deploy pipeline connecting them.

Headless projects get harder to reason about when the backend and frontend are built by different people who don’t talk to each other. API shape decisions get made without knowing what the frontend needs, and SEO and structured data that a WordPress theme handles automatically has to be rebuilt by hand.

Every 84EM engagement is handled directly by a principal engineer, 14 years in WordPress as part of 31 years engineering for the web. The same person scopes the API, builds the frontend, and hands off a system a future developer can actually maintain.

What can 84EM build with headless WordPress?

WordPress REST API backends shaped with custom fields, custom endpoints, and a real auth strategy, static frontends in Hugo or Astro, JavaScript frontends in Next.js or Nuxt when a client runtime earns its cost, and multi-tenant architectures serving several sites off one WordPress backend.

WordPress REST API Backends

Custom fields, custom endpoints, and a real auth strategy for anything beyond public content. WordPress stays the editor; the API is shaped to what the frontend actually needs.

Static Site Frontends

Static HTML generated at build time in Hugo or Astro, with no client runtime required to render a page. A build triggers whenever content changes, so editors keep a normal publishing workflow.

JavaScript Frontends

Next.js, Nuxt, or vanilla JavaScript when a client runtime is the right call – interactive features, real-time data, or an app-like experience the content actually needs.

Multi-Tenant Platforms

One WordPress backend serving multiple sites or niche directories, each with its own frontend and its own scoped search index, without multiplying backend infrastructure per site.

SEO and Structured Data on a Headless Frontend

Sitemaps, meta tags, and structured data that a WordPress theme and SEO plugin normally handle automatically, rebuilt on the new frontend so nothing is lost in the move off traditional WordPress.

Proof of Work

High-Performance Business Directory with Passwordless Listing Management

Data & Integrations

A niche directory needed to serve thousands of location-based listings with instant page loads while letting store owners manage their own listings without creating accounts. A headless WordPress architecture delivered sub-second performance and passwordless listing management that improved submission rates.

Traditional WordPress, or headless?

Traditional WordPress with good caching performs fine for a standard site and keeps the built-in convenience of themes and page builders. Headless pays off once performance, security, or scale outgrow what that convenience is worth.

Traditional WordPress fits when

Good caching already delivers acceptable performance
Editorial teams rely on the WordPress theme and page builder directly
The site doesn’t need to serve multiple frontends or channels from one backend
There’s no dedicated resourcing for a separate frontend build and deploy process

Headless WordPress fits when

Traffic or content volume make traditional page loads too slow
Security requirements favor no public-facing WordPress install at all
One backend needs to serve multiple sites, apps, or channels
Performance and scale outweigh the cost of maintaining two stacks

His contributions have had a direct, meaningful impact improving overall site performance while enhancing reporting capabilities and activity tracking.

Frequently Asked Questions

Do you build headless WordPress sites?

Yes. 84EM builds headless WordPress: WordPress as a content backend exposed through its REST API, with a separate system building and serving the frontend, for sites where performance and scale matter more than built-in templating.

Do you only build headless WordPress frontends in Hugo?

No. 84EM builds whatever frontend actually fits the project -- Hugo, Astro, Next.js, Nuxt, or vanilla JavaScript. Hugo runs 84EM's own production directory platform, but the frontend choice depends on the project's traffic and performance needs, not a fixed stack.

Can you build a multi-tenant directory on headless WordPress?

Yes. One WordPress backend can serve multiple niche directories, each with its own static frontend and its own scoped search index, without multiplying backend infrastructure per site.

Is headless WordPress right for my site?

It depends on scale. Headless is worth it when performance, security, or scale matter more than the convenience of WordPress's own templating and page builders. For a standard site, traditional WordPress with good caching already performs fine.

Do you do WordPress development?

Yes. WordPress development has been 84EM's core focus for 14 years, part of 31 years engineering for the web. Bespoke plugins, AI integrations, APIs, and custom workflows. See case studies for examples.
