Headless CMS

In a traditional CMS like WordPress, the same system stores your content and builds the pages from a theme. A headless CMS removes the “head”, the presentation layer. Editors still get a dashboard with fields, drafts and publishing, but the content goes out as structured data through an API. A developer-built front end fetches it and decides how it looks. Common headless options are Sanity, Contentful, Storyblok, Payload and Strapi.

Why it matters for a SaaS website

The choice shapes who can change the site and how fast. A headless setup suits teams that need:

• One source for many outputs. The same customer story or changelog entry can feed the marketing site, the docs, the app and an email.
• Content modelled as content, not pages. Integrations, case studies, customers and authors become linked types instead of copy pasted into page templates. That structure also makes pages easier for search and answer engines to read.
• Custom front-end requirements. Interactive demos, logged-in states, or performance targets that a page builder can’t hit.

The trade-off is cost and ownership. You now run two systems, the CMS and the front end, and new page layouts usually need a developer. For a 20-page marketing site that changes weekly, that is often the wrong trade.

How DesignMe handles it

We start with who edits the site and how often, not with the stack. If marketers need to ship new pages without a developer, we usually recommend Framer or Webflow, where the CMS and the visual editor live together. When the site needs custom logic, shared content with the product, or a very large page count, we design the content model first and then build the front end in Next.js or Astro on top of a headless CMS. Editors get named fields and previews, not a blank rich-text box.

Example

Say a data platform keeps 60 integration pages, each with a logo, a category, setup steps and related use cases. In a headless CMS each integration is one entry with those fields. The Next.js site builds an integrations directory, a page per integration and “works with” blocks on the use-case pages, all from the same entries. Adding an integration is one new entry, with no layout work.

Common mistakes

• Going headless for speed alone. A well-built Framer or Webflow site is fast too. Pick headless for content structure or custom needs.
• No preview. Editors who can’t see a draft before publishing stop trusting the system. Set up live preview from day one.
• Rebuilding WordPress page soup. Moving unstructured “page body” blobs into a new CMS keeps every old problem. Model the content before you migrate it.
• Client-only rendering. Fetching content in the browser leaves crawlers and AI tools with an empty page. Render on the server or at build time.
