Kirby

Kirby stores content as plain files and folders, eliminating the need for a database and allowing developers to work directly with the file system. The core application provides a panel for editors, while the underlying architecture lets users define custom content structures, forms, galleries, and other components through simple configuration. Because everything is file‑based, the system can be deployed on any web server that supports PHP without additional services.

The CMS is aimed at developers, designers, and content creators who want a lightweight, self‑hostable solution that can be shaped to fit a wide range of projects—from small sites to complex applications. Its flexibility comes from the ability to extend the panel, create bespoke templates, and integrate arbitrary data types without being constrained by a fixed schema.

Kirby is distributed under a proprietary license, with a free trial available for local development or testing. The project is actively maintained, includes continuous‑integration testing and code‑coverage reporting, and encourages community contributions through its issue tracker, feedback platform, and documentation.
