Disadvantages of headless CMS
Headless CMS is designed for developers and, as a result, is usually tricky for marketers to use if they don't have a technical background. Headless offers a limited number of traditional marketing tools, such as content preview, collaborative functionality, and on-page editing.
Requires third-party tools to create static pages quickly
It doesn't include security, caching, and infrastructure-based features.
You can't preview content.
Initial integration and configuration effort is more time and resource-intensive
Advantages of traditional CMS
Quick and easy to deploy and install for small businesses
Design templates make systems user-friendly for non-developers
Simple content management and collaboration
The platform centralizes all content, so you can easily plan, publish, and edit from one interface.
Lots of communities and resources to tap for support
Disadvantages of traditional CMS
Loss of flexibility as your website grows
Limited to creating web content
Requires additional resources for maintenance
Developers must have CMS-specific knowledge and skills
Conclusion: Choosing your CMS
A traditional CMS is an excellent place to start if you're a marketer or work on a small team beginning to design a website. However, if you are working with developers and don't want to rely on templates for your site, or if you need more advanced functionality, you could do well to go with a headless CMS. Choosing this option is only recommended if you have the time, resources, and expertise necessary to configure the system successfully.
There is also a third option: a hybrid CMS, a platform that gives both marketers and developers the freedom they need to deliver content across multiple channels. A hybrid CMS gives you the best of both worlds, providing marketers access to interfaces they're familiar with while allowing a developer to prepare content for third-party other applications. Whatever course you choose, take your time, test the systems and select the option that best fits your needs.
