(FAQ)

Common questions about
headless CMS development.

What is a headless CMS and why does it matter?

A traditional CMS (like classic WordPress) tightly couples the content management backend to the frontend that renders it. A headless CMS separates the two, your content lives in a dedicated CMS (Sanity, Contentful, etc.) accessible via API, and your frontend (Next.js) fetches and renders it. The result is a much faster site, better developer experience, and a content model that can serve web, mobile, and other channels from a single source of truth.

Sanity vs Contentful, which should we choose?

Sanity is generally better for content-heavy sites with complex, custom content models, the Studio is highly customisable and the GROQ query language is very powerful. Contentful has a slightly simpler learning curve and better-established enterprise integrations. For most marketing sites and mid-complexity content, Sanity is our recommendation. For large enterprises with existing Contentful investment, we build against Contentful. We advise based on your specific content and team requirements.

Should we go headless or stay on traditional WordPress?

If your current WordPress site is fast enough and your editors are happy, going headless is probably unnecessary complexity and cost. If you're experiencing performance issues, developer frustration, or scaling challenges, or if you need to serve content to multiple frontends or channels, headless pays off. We give an honest recommendation during the discovery call based on your actual situation.

Can editors preview content before publishing?

Yes. We implement live preview for every headless build. With Sanity, this uses the Presentation tool with real-time overlays. With Contentful, it uses the Preview API with a Next.js draft mode. With headless WordPress, we use WP's preview post functionality hooked into Next.js. Editors can see exactly how content looks before it goes live.

How do you handle content migration from our existing CMS?

We write automated migration scripts to export content from your existing CMS and import it into the new one, transforming data structures along the way. Images are downloaded and re-uploaded to the new CDN. A redirect map is created to preserve all existing URLs. The migration is run in dry-run mode first for review, then executed to the new CMS before launch.

How much does headless CMS development cost?

A marketing site with Sanity and Next.js (10–20 content types, editorial preview, basic migration) typically costs £8,000–£15,000. A larger site with complex content modelling, multi-language support, or significant migration work typically costs £15,000–£30,000. Flat written quote after a free discovery call.
