Do I Need a Headless CMS?

This depends on a few factors, such as the website or project size.nnDigital publishing companies that only produce and distribute content through a single content stream (such as their web and mobile applications) don’t require the backend complexities of a headless CMS.nnThis is because traditional CMS platforms already offer the necessary capabilities to manage a single content stream with smaller projects faster and more effectively.

Is WordPress a Headless CMS?
