Foundations of CMS

When it comes to the foundations of a CMS, Grav and Kirby take different approaches. Grav is an open-source flat-file CMS built on modern web technologies such as Markdown and YAML. It uses a file-based data structure, where content is stored in plain text files rather than a traditional database. This approach provides flexibility, speed, and easy version control. On the other hand, Kirby is a file-based CMS with a minimalist and user-friendly interface. It utilizes a folder structure for organizing content and leverages text files for storing data. This structure makes Kirby highly customizable and enables you to define your own content types and fields with ease.

Both CMS provide efficient and lightweight foundations, but Grav's file-based approach might be more appealing if you prefer simplicity and speed, while Kirby's customizable structure suits those who require more control over their content organization.

Additionally, it's worth noting that Grav is built using PHP and follows the principles of the popular PHP framework, Symfony, making it suitable for developers familiar with PHP. On the other hand, Kirby is built on a proprietary PHP framework that is specifically designed for the CMS itself, ensuring optimal performance and security.

In summary, while both CMS have solid foundations, Grav takes a flat-file approach that emphasizes flexibility and speed, while Kirby provides a customizable folder structure for those who desire more control.

In summary, Grav offers a broader selection of themes and a more feature-rich admin panel, making it ideal for those who value extensive customization and a user-friendly CMS.
