Headless content management system supporting composable, API-first architectures
Discover top open-source software, updated regularly with real-world adoption signals.

Fast, file-based CMS with zero installation required
Modern flat-file content management system powered by PHP, Markdown, and Twig. No database needed—extract, deploy, and start building immediately with powerful package management.

Grav is a file-based web platform that eliminates database complexity while delivering exceptional speed and flexibility. Designed for developers and content creators who value simplicity, Grav requires zero installation—extract the archive and you're running. Its flat-file architecture stores content in Markdown and configuration in YAML, making version control and deployment seamless.
Grav leverages proven components including Twig templating for UI control, Symfony Event Dispatcher for extensibility, Doctrine Cache for performance, and Parsedown for fast Markdown rendering. The integrated Grav Package Manager (GPM) streamlines plugin and theme installation, updates, and core upgrades through simple CLI commands.
Ideal for developers building marketing sites, documentation portals, blogs, and small-to-medium web projects where database overhead is unnecessary. The PHP 7.3.6+ requirement and Composer support make it accessible to modern PHP developers, while the CLI tooling and Git-friendly file structure appeal to DevOps-minded teams seeking reproducible deployments.
When teams consider Grav, these hosted platforms usually appear on the same shortlist.
