What Headless WordPress Actually Decouples — And What Stays Put

Your content team logs into wp-admin exactly as they do now. Your developers pull that content through REST or WPGraphQL and render it with Next.js Server Components, cached at 100+ edge locations. The WordPress database, ACF fields, user roles, plugin ecosystem — all untouched. What dies: the PHP theme layer that keeps your Lighthouse mobile score between 40 and 55, the attack surface of wp-login exposed to the public internet, and the single point of failure where one bad plugin update kills editorial access and visitor experience in the same stroke. Incremental Static Regeneration pre-renders pages on-demand and revalidates them in the background, so your traffic spikes hit a CDN, not your origin server.

Wo Projekte scheitern

Lighthouse mobile scores stuck between 40 and 55, even after you've thrown every caching plugin at it Google penalizes slow pages in search rankings, and every 100ms delay eats into your conversions.
PHP themes are a single point of failure One bad plugin update can take everything down at once — editors and visitors lose access together.
Editors like wp-admin Developers hate writing PHP templates. And hiring decent frontend talent gets harder and more expensive every year.
WordPress exposes your entire application stack to the public internet Brute-force attacks on wp-login, XML-RPC exploits, plugin vulnerabilities — they're all live attack surfaces, right now.
Page builders and shortcodes lock your content inside rendering engines that fight performance That content also becomes non-portable — you can't pipe it to a mobile app or any other channel without a fight.
Server-rendered PHP can't keep up with static or ISR delivery at the edge Traffic spikes strain your server, push up hosting costs, and degrade the experience for everyone hitting your site at the same time.

Compliance

WPGraphQL Integration

We wire up WPGraphQL to expose posts, pages, custom post types, ACF fields, and Yoast metadata as efficient GraphQL queries. No over-fetching, no wasted bandwidth.

Incremental Static Regeneration

Pages get statically generated at build time and revalidated in the background on a configurable interval. Visitors always hit a cached edge response while the content stays current behind the scenes.

Draft Preview for Editors

Next.js Draft Mode intercepts preview clicks from wp-admin and renders unpublished content through the production frontend. Editors see exactly what visitors will see — no surprises, no "it looked different in preview."

SEO Metadata Pipeline

Yoast and Rank Math data flows through the API into Next.js generateMetadata. Titles, descriptions, Open Graph tags, canonical URLs, JSON-LD structured data — all handled automatically.

Attack Surface Reduction

Your WordPress instance sits behind a firewall with no public theme rendering. Only the API endpoint is exposed, which cuts out most of the common WordPress exploit vectors.

On-Publish Revalidation

A lightweight webhook fires the moment an editor hits Publish. That triggers on-demand ISR, so updated content goes live in seconds — no full rebuild required.

Was wir bauen

Escape Lighthouse mobile scores trapped between 40 and 55 despite every caching plugin you've installed

Ship Lighthouse 95+ on mobile with Server Components that eliminate client-side JavaScript overhead and trim Time to Interactive

Eliminate the single point of failure where one plugin update crashes both your editorial interface and your public site

Serve static and ISR pages from 100+ edge nodes so your site stays live even if the WordPress origin goes down entirely

Stop forcing frontend developers to write PHP templates when React talent is cheaper and easier to hire

Map ACF Pro custom fields and repeater blocks to typed TypeScript interfaces for predictable, compile-time-safe rendering

Close the attack surface of wp-login, XML-RPC, and plugin vulnerabilities exposed to the public internet

Run WordPress media library images through automatic WebP/AVIF conversion, lazy loading, and responsive srcsets via Next.js Image

Break free from page builders and shortcodes that lock your content inside non-portable rendering engines

Generate dynamic XML sitemaps and RSS feeds at build time from your content graph and auto-submit them to Search Console

End the cycle where traffic spikes strain your server, inflate hosting costs, and slow the site for everyone

Expose WPML or Polylang locale data via the API and route it through Next.js i18n with intact hreflang tags for every language

Unser Prozess

01

WordPress Audit & API Setup

We start with an audit of your existing WordPress instance — plugins, custom post types, ACF fields, SEO configuration. We install WPGraphQL, expose all content types, and lock down the public-facing PHP layer.
Week 1
02

Next.js Frontend Build

Then we scaffold the Next.js app with App Router, map every WordPress template to a React component, and configure ISR with tuned revalidation intervals. Draft Mode preview gets wired up for your editors at this stage.
Weeks 2–3
03

SEO & Performance Tuning

Yoast and Rank Math metadata gets piped into generateMetadata. We optimize images, implement structured data, configure sitemap generation, and keep iterating until every Lighthouse category is clearing 95.
Week 4
04

Editor Training & QA

Your content team then tests the full editorial workflow end to end — draft, preview, publish, revalidate. We work through every edge case: custom fields, scheduled posts, revision history, multi-author workflows.
Week 5
05

Deploy & Monitor

Finally, we deploy to Vercel with production caching, configure on-publish webhooks, set up uptime monitoring for both the WordPress API and the Next.js frontend, and stay on for 30 days of post-launch support.

Häufige Fragen

Müssen meine Editoren ein neues CMS lernen?

Nein. Das wp-admin Erlebnis ist identisch — gleiches Dashboard, gleicher Editor, gleiche Plugin-Schnittstellen. Die einzige sichtbare Änderung ist, dass Klicks auf Vorschau durch den Next.js Frontend via Draft Mode statt durch ein PHP Theme geleitet werden. Die meisten Editoren bemerken es nicht einmal, außer dass die Vorschaulade schneller laden.

Funktionieren meine bestehenden WordPress Plugins noch?

Backend-Plugins wie ACF, Yoast, Gravity Forms und WooCommerce funktionieren normal weiter. Plugins, die HTML via PHP Hooks injizieren — visuelle Page Builder zum Beispiel — müssen durch React Komponenten ersetzt werden. Wir prüfen jedes Plugin während der Discovery und kennzeichnen alles, was migriert werden muss, bevor wir eine Zeile Code anfassen.

Wie handhaut Headless WordPress SEO ohne ein PHP Theme?

Sowohl Yoast als auch Rank Math exposieren alle SEO Metadaten durch die REST API und WPGraphQL. Wir ziehen Titel, Meta Descriptions, Open Graph Tags, Canonical URLs und Schema Markup in Next.js generateMetadata. Die Ausgabe entspricht dem, was du vorher hattest — normalerweise besser — und du bekommst dramatisch schnellere Page Loads obendrauf, was Platzierungen direkt hilft.

Welchen Lighthouse Score kann ich realistischerweise erwarten?

Wir streben 95+ über Performance, Accessibility, Best Practices und SEO auf mobil und Desktop an. Monolithisches WordPress erreicht typischerweise 40–55 auf mobil. Statische Generierung, ISR, Edge Caching und optimierte Bildbereitstellung schieben diese Zahlen in der Produktion konsistent über 95.

Was passiert mit meiner Website, wenn der WordPress Server ausfällt?

Nichts, das Besucher bemerken würden. Next.js bedient vorgerenderte Seiten aus dem Edge Cache, sodass das Frontend während eines WordPress Ausfalls vollständig operativ bleibt. Editoren können keine neuen Inhalte veröffentlichen, bis das Backend wiederhergestellt ist, aber Besucher sehen null Ausfallzeit. Das ist ein echter Resilienz Vorteil gegenüber monolithischem WordPress.

Wie lange dauert eine Headless WordPress Migration?

Eine typische Website — unter 200 Seiten, Standard Custom Post Types, ACF Felder — dauert 5–6 Wochen vom Start bis zur Produktion. Größere Projekte mit WooCommerce, mehrsprachiger Unterstützung oder komplexer Custom Plugin Logik können 8–10 Wochen dauern. Wir definieren alles während der Discovery präzise, damit dich nichts während des Projekts überrascht.
