Headless WordPress: decide from requirements, not market claims
Headless WordPress separates content management from the application that displays the content. It can suit multiple publishing channels or a custom frontend, but it introduces another application to build and maintain.
Define the publishing workflow
List the content types, languages, previews, search and forms your team needs. The WordPress REST API provides an interface to content; it does not automatically reproduce every theme or plugin feature in a separate frontend.
Budget for the whole system
Include frontend development, hosting, authentication, caching, monitoring and deployment work. Test how editors preview drafts and how published changes reach visitors. A headless architecture does not by itself guarantee lower costs, faster pages or higher productivity.
Run a small acceptance test
Build one representative page and one interactive journey. Check accessibility, metadata, redirects, error handling and recovery after an API failure. Compare the result with a conventional WordPress implementation before committing. The earlier unsupported adoption, savings and productivity percentages have been removed.
