What Is Headless WordPress and When Should You Use It?

Headless WordPress uses WordPress as a backend CMS with a separate frontend built in React, Vue, or Next.js. Content is managed through the WordPress admin and delivered via the REST API to a custom frontend. I have built 4 headless WordPress sites for clients who needed custom interactive frontends that the standard WordPress theming system could not deliver effectively.

What Are the Benefits of Headless WordPress?

Faster frontend performance (React/Vue sites load 2-3x faster than standard WordPress themes), complete design freedom, ability to use modern JavaScript frameworks, and security through decoupling the backend from public access. Major companies like TechCrunch and Facebook use headless CMS architectures. The tradeoff is higher development complexity and ongoing maintenance of both the backend and frontend codebases.

What Are the Downsides of Going Headless?

Higher development cost (typically 3-5x more than a standard theme), loss of visual editing in the frontend, no drag-and-drop page builders, and more complex deployment pipelines. For most content sites, a standard WordPress setup with a lightweight theme is more practical. I recommend headless only when you need custom interactivity that standard WordPress cannot provide.
