A content management system (CMS) is a piece of software that enables users to build and modify websites quickly and easily using the platform instead of HTML code. This means users can build powerful, intuitive websites and pages without needing the extensive coding knowledge it would require to build one from scratch.
As standard, a CMS platform should come with a centralized dashboard, where users can view all website statistics, recent activity, manage content, and draft new pages or posts. Another essential feature is a content editor tool, which enables users to not only create new pages but also modify and update existing ones. Some CMS platforms might also come with libraries of themes and templates, which users can leverage to design their pages and layouts, as well as built-in SEO tools to help users drive relevant and meaningful traffic to their sites.
But not all CMSs are made equal, and there are three broad categories of CMS that you can choose from. These are coupled, decoupled, and headless CMSs. Coupled CMSs are the traditional types, and mean that frontend and backend functionalities are paired together on one system. While decoupled CMSs separate the frontend and backend onto two separate systems. Headless CMSs are technically a subset of decoupled, but what makes them their own category is that they include a backend but no frontend.
CMS software listed in this category include a mix of coupled, decoupled, and headless CMS, as well as both open-source and proprietary software.
