What Headless CMS Actually Decouples — And What Stays Connected

Your editor hits publish. The webhook fires. Your Next.js frontend rebuilds in 22 seconds, pulling fresh content through a GraphQL layer that validates every field before it renders. That's headless CMS: your content lives in a structured repository (Sanity, Contentful, or Strapi), served through APIs to any frontend your business needs — website, mobile app, digital kiosk, email template. Traditional platforms bundle content storage, editing UI, and frontend rendering into one brittle monolith. Headless splits them. Editors get a purpose-built dashboard with custom workflows and role-based permissions. Developers build in React or Vue without touching the CMS codebase. Your pages load in under 1.2 seconds because they're static-rendered at build time, not assembled per request. When you need to publish to a new channel, you query the same API — no content duplication, no second CMS licence. The architecture scales without forcing a platform migration every three years.

Wo Projekte scheitern

WordPress or Drupal rebuilds take months and still feel sluggish You spend six figures on a monolithic rebuild that fails Core Web Vitals within a year.

Editorial teams are blocked by developers for every content change Publishing bottlenecks slow campaigns and cost revenue during peak periods.

Your content is locked inside a single platform with no API access Expanding to mobile apps or new channels means duplicating content by hand.

Page load times exceed 3 seconds despite caching plugins Google penalises slow pages, and bounce rates climb above 50% on mobile.

Your CMS vendor raised prices and migration looks impossible Annual licensing costs compound while you stay locked into their ecosystem.

Multiple microsites each run their own CMS with separate logins Brand inconsistency, duplicated effort, and security vulnerabilities multiply across properties.

Compliance

Content Modelling

We design structured content schemas that serve web, mobile, and future channels from a single source of truth. Every field is typed, validated, and documented.

Preview & Visual Editing

Live preview environments let editors see changes before publishing. No more guessing what content looks like on the frontend.

API Security & Auth

API keys, RBAC, and webhook verification are configured from day one. Content delivery endpoints are read-only and rate-limited.

Edge Caching & ISR

Content is served from Vercel's edge network with Incremental Static Regeneration. Pages revalidate in seconds, not minutes.

Migration & Import

We extract, transform, and load content from your existing CMS with full revision history. Zero content loss, verified with checksums.

Analytics & Content Performance

Structured content enables granular analytics tracking per component and content block. Measure what actually drives conversions.

Häufige Fragen

What is a headless CMS and how is it different from WordPress?

A headless CMS stores and manages content but has no built-in frontend. Content is delivered via APIs to any frontend — Next.js, mobile apps, kiosks. WordPress couples content and presentation together, which limits performance and multi-channel delivery. Headless gives you editorial flexibility without frontend constraints.

Which headless CMS should I choose: Sanity, Contentful, or Strapi?

Sanity suits teams that want maximum customisation and real-time collaboration. Contentful is strong for enterprise organisations with complex content governance. Strapi is open-source and self-hosted, ideal when data sovereignty matters. We assess your editorial workflow, budget, and technical requirements before recommending a platform.

How long does a headless CMS project take to build?

Most headless CMS projects run six to eight weeks from content audit to launch. Simple marketing sites with under ten content types can ship in four weeks. Complex builds with multi-language support, e-commerce integration, or large content migrations may take ten to twelve weeks.

Can you migrate our existing WordPress content to a headless CMS?

Yes. We build automated migration scripts that extract posts, pages, media, taxonomies, and metadata from WordPress. Content is transformed into structured schemas, validated against the new model, and imported with full revision history. We verify every record with checksums before decommissioning the old system.

Will our editors need to learn to code to use a headless CMS?

No. Modern headless CMS platforms like Sanity and Contentful provide visual editing interfaces. We customise these studios with drag-and-drop page builders, live preview, and role-based dashboards so your editorial team works faster than they did in WordPress — without touching code.

How much does headless CMS development cost in London?

Our headless CMS projects start at £6,000 for a standard marketing site with CMS setup, content modelling, and a Next.js frontend. Larger builds with content migration, multi-language support, and custom integrations typically range from £14,000 to £25,000+. All projects are fixed-fee with no hourly billing surprises.
