What is Kirby CMS?

Kirby CMS is a flexible and user-friendly content management system that is characterised by its ease of use and adaptability. It enables designers and developers to create customised websites without being restricted by unnecessarily complex programming or prefabricated templates.

With its file-based architecture, Kirby offers a unique alternative to database-driven systems, making it ideal for projects of any size.It is characterised by an intuitive user interface and strong community support, making it an excellent choice for creative and dynamic online projects.

Advantages at a glance

That's why the Kirby content management system is an excellent choice for customised websites:

  • Flexibility and customisability: Kirby CMS enables the individual design of websites without the restrictions of predefined templates. This allows us to develop unique and customised online solutions for our customers.
  • Ease of use: With its user-friendly interface, content can be managed quickly and efficiently, increasing productivity and minimising training time for new users.
  • File-based structure: In contrast to database-based CMS, Kirby is based on a file-based architecture, which enables fast and flexible handling of projects of any size and at the same time offers enormous performance.
  • Future-proof business model: Kirby CMS has been developed for over 10 years by Content Folder GmbH & Co. KG, which ensures continuous further development with a fair pricing model.
  • Strong community and expandability: An active developer community and a variety of plugins and extensions offer developers additional resources and support to customise and optimise their projects.
  • High maintainability: Thanks to its clear and well-organised structure, Kirby CMS is particularly easy to maintain. Customers benefit from easy updatability and scalability, which simplifies long-term projects and lowers the total cost of ownership.

Headless, with brains

In the rare cases where a more complex front-end application is required, Kirby CMS, combined with the KQL Core Plugin, can open up new horizons as an efficient headless CMS. With the KQL plugin, Kirby is transformed into a powerful data source that can be queried via a Graph QL-like API. This flexibility allows agencies and developers to utilise Kirby's robust backend as a content repository while independently designing the frontend using any technology - such as Vue or Svelte. This separation of content and presentation offers immense flexibility, scalability and the ability to create innovative web experiences that are customised to the exact needs and expectations of the customer.

Static websites with CMS

The Staticache plugin is an extension for Kirby CMS that can increase the performance of websites even further. This plugin generates static versions of Kirby pages, which reduces loading times and server load at the same time. The statically generated HTML pages are delivered directly from the web server, ideal for high-traffic sites. The panel remains active and can be used by editors to edit content. The cache is deleted each time the page is saved and regenerated the first time it is called up. This combines the performance of a static page with the convenience of a content management system.
