Platform Overviews
Contentful
Contentful is the world's leading headless Content Management System, used by enterprise teams at Nike, Spotify, and Burger King to manage content across websites, apps, and digital experiences from a single platform. Unlike traditional CMS platforms, Contentful separates content storage from presentation entirely — it provides a REST API and GraphQL API that any frontend framework can query, then renders content through whatever technology the team chooses. This architecture means Contentful often powers Next.js, Gatsby, or Nuxt frontends rather than having its own rendering layer. Sites backed by Contentful are identifiable through their media CDN domains: images.ctfassets.net and downloads.ctfassets.net serve all stored assets, and these URLs appear in image src attributes and link hrefs throughout the page. Contentful plans start at a free Community tier, with Team plans from $300/month for professional workflows.
Joomla
Joomla is a veteran open-source CMS that holds the second-largest market share among self-hosted CMS platforms after WordPress — powering millions of sites for small businesses, government agencies, and non-profits worldwide. Its flexible user access management (ACL) and multilingual support built into the core (no plugin required) make it popular for organizations with complex permission structures and international audiences. Joomla's extension directory has 8,000+ extensions for adding functionality. Joomla sites are identifiable through /media/jui/ paths for jQuery UI assets, com_content references in URL query strings (index.php?option=com_content), the Joomla generator meta tag containing the version number, and /administrator/ path for the backend. The Joomla JavaScript namespace and component-specific CSS classes (mod-articles-category, com_content) appear throughout the markup. Joomla is free and open-source.
