A headless content management system, or CMS, is a type of CMS that separates the content (the "body") from the presentation layer (the "head"). In a headless environment, content is created, managed and stored in a central hub and delivered via APIs to any front-end framework or device. This provides greater flexibility and scalability for developers and content creators.

Frequently asked questions

  • What is a headless CMS? A headless CMS is a content management system that provides all the backend tools needed to create and publish content via APIs, but leaves the front-end tasks to the developer. This creates a clear separation between content management and presentation.
  • How does a headless CMS work? A headless CMS stores content in a repository and makes it available through an API. Developers can then use any front-end technology they choose to build websites and applications that consume the content from the API.
  • What is the difference between a headless CMS and a traditional CMS? A traditional CMS, also known as a coupled CMS, tightly binds the front-end and the backend. A headless CMS, on the other hand, is front-end agnostic, meaning it works without a front-end.
  • What are the benefits of a headless CMS? Some of the key benefits of a headless CMS include:
    • Unmatched flexibility and agility
    • The ability to create experiences 2-10x faster with modular blocks, live preview, JSON rich text editor and environments
    • The freedom to choose the front-end framework that works best for your needs
    • Increased developer velocity
  • Is a headless CMS right for my business? A headless CMS is a good choice for businesses that need to deliver content to multiple channels, such as websites, mobile apps and IoT devices. It is also a suitable option for businesses that wish to utilize modern front-end frameworks and technologies.
  • What are some use cases for a headless CMS? Some common use cases for a headless CMS include:
    • Websites and web applications
    • Mobile apps
    • E-commerce sites
