Headless WordPress
WordPress as the CMS, Next.js as the frontend — keep editorial in WP, ship a faster site.

01 What it is
What this service is
Headless WordPress means using WordPress as a pure content management system — editors continue working in the WP admin — while the public site is a separate Next.js, Astro, or Nuxt application that consumes content via WPGraphQL or the REST API. The two are decoupled: editorial workflow stays familiar, frontend performance and flexibility unlock.
At devinsta we use WPGraphQL with persisted queries for performance and predictability, and we run the WP admin on a dedicated subdomain with restricted access (no public surface area beyond the API).
02 What it's for
What it's for
Headless WordPress earns its keep when editorial wants to stay in WordPress but the front-end has outgrown what themes can do — typical triggers are a stuck Lighthouse score, a brand redesign with motion and interactivity that themes can't support, or a need to serve multiple frontends (web, mobile, kiosk) from one content source.
03 How to use it
How to engage devinsta
We start with an audit of the current theme to understand which custom fields and blocks need to be exposed via API. We then build the Next.js frontend in parallel with the existing site, point a staging environment at the production WP, and cut over with a measured DNS swap and complete 301 redirect map.
04 How to deploy
How we deploy it
Frontend deploys on Vercel or Cloudflare Pages with ISR — most pages cache for hours and revalidate on edit via webhooks from WP. The WP admin runs on managed hosting (WP Engine, Pantheon) with HTTP basic auth or IP allowlisting in front of /wp-admin. Media is offloaded to S3 / R2 with a CDN; the WP server never serves images directly.
This means the front-end is incredibly fast and resilient (you can take WP offline for maintenance with no public impact), and the editorial experience is identical to before.

FAQ
Common questions
Will editors notice the difference?
Almost never. The WP admin is unchanged — same Gutenberg editor, same Yoast / Rank Math SEO, same workflow. Edits appear on the live site via webhook-triggered ISR within seconds. Most editors don't realise the front-end is decoupled.
What about WP plugins that inject frontend JS?
Those won't work — anything that hooks the_content or wp_head won't reach a headless frontend. We catalogue the plugin estate during audit and either find headless-compatible replacements, port the functionality into the Next.js app, or accept the trade-off.
What about preview?
Live preview works — we wire WP Preview into Next.js draft mode so editors see the headless frontend's exact rendering before publishing.
