Headless WordPress

Traditional WordPress commonly handles both content administration and theme rendering. In a headless setup, editors still create posts, pages and structured content in WordPress, but a separate application retrieves that content through the WordPress REST API or another suitable interface. The public site might use Astro, Next.js or another framework and can be deployed independently of the CMS dashboard.

This separation can make complex interfaces and multichannel publishing easier to design, but it introduces operational work. Teams must plan previews, authentication, media URLs, content changes, revalidation and cache invalidation. A fast static front end is only part of the architecture; unpublished drafts and private content must not leak through public API requests or build artifacts. SEO metadata and canonical links must be rendered correctly.

Headless WordPress is a specific implementation of the broader Headless CMS concept. It does not automatically make a site faster, safer or cheaper, and it is not synonymous with installing a particular plugin. The trade-off makes sense when independent frontend requirements justify the integration and maintenance costs.
