Grav is a modern, open-source flat-file CMS, designed for speed and simplicity. Unlike traditional CMSs, it uses no database: all content is stored in Markdown files with YAML headers, making sites easy to version with Git, back up, and migrate.

Under the hood, Grav relies on proven PHP components (the Twig template engine, Markdown parsing, multi-level caching) to serve pages in milliseconds. An integrated package manager (GPM) provides access to a wide ecosystem of themes and plugins covering forms, SEO, multilingual support, and lightweight e-commerce.

An optional admin panel offers a user-friendly visual editor for writers, while developers benefit from a flexible architecture, possible headless approach, and great customization freedom. It is an excellent choice for brochure sites, blogs, documentation, and high-traffic portals.
