Kirby

Kirby is a file-based content management system (CMS) built with PHP that stores content in structured text files rather than databases. The platform provides a flexible, developer-friendly approach to content management with a clean administrative panel for editors. Kirby uses a flat-file architecture where pages, content, and metadata are stored in folders and text files, making version control and deployment straightforward. The CMS offers a powerful templating system that gives developers complete control over HTML output and site structure. Kirby includes a customizable Panel (admin interface) that can be tailored to match specific content workflows and user permissions. The system supports multi-language content, custom fields, and extensibility through plugins and custom code. Kirby is popular among web developers, designers, and agencies building custom websites, portfolios, and small to medium-sized web projects where flexibility and developer control are priorities over out-of-the-box features.
