A headless CMS separates where your content lives from where it appears. We design the content model, build the front end, migrate what you already have, and manage the whole thing — so your team edits in a clean interface while pages serve from the edge in milliseconds.

## What it does

Designs the content model, builds the front end, migrates existing content and runs a headless CMS end to end — Sanity, Storyblok, Contentful, Strapi or Payload, served through Astro on Cloudflare.

## Where it creates value

The publishing engine of the value stream: it decouples how fast your team can publish from what it costs to change the site, so content ships in minutes and every channel draws from one source.

## Why it cannot be ignored

A monolithic CMS ties your content to one template on one site. The moment you need a second brand, another language, an app or a partner feed, you are re-keying the same content by hand — and paying for a rebuild every time the design changes.

## What you get

- **Modelled, not improvised** — Content types, relationships and reuse designed up front — so the same content serves the site, the app and the feed without being duplicated.
- **Migrated with the history intact** — Existing pages, media, URLs and redirects moved across, so rankings and inbound links survive the move.
- **Fast because it is static** — Pages built at publish time and served from Cloudflare's edge — no database sitting between your visitor and the page.
- **Editors keep control** — Previews, scheduled publishing and role-based permissions, so marketing ships without a developer in the loop.

## Key concepts

- **Headless CMS** — A content system with no front end of its own — it stores and serves content through an API, and the website is built separately. When the same content has to appear on more than one surface, or you want to redesign the site without touching the content.
- **Content modelling** — Defining the shape of your content — the types, the fields and how they relate — before anything is built. It is the decision that determines whether the next five years of publishing is easy or painful. It is also the one most often skipped.
- **Composable architecture** — Choosing a specialist tool for each job — content, search, commerce, identity — and joining them, rather than accepting one vendor's version of everything. When a single platform is holding back one part of the business and you cannot replace just that part.
