What DedeCMS is
DedeCMS is a self-hosted PHP and MySQL content management system for building websites. It runs on Windows, Linux, or Unix environments through web servers such as IIS, Apache, or Nginx. Windows and Linux or Unix setups require PHP 5.6 or later with MySQL 5.7 or later or MariaDB. File-based XML namespace templates use template tags for customization, while models and modules support classification, library, yellow pages, circles, and Q&A functions. SEO settings can be adjusted, and dynamic or static page deployment is described as supporting indexing. The download page lists versioned security and feature patches. Setup guidance recommends OpenBSD, low-privilege system and database accounts, and deleting the install directory after setup. A free license costs nothing for personal nonprofit websites, with unlimited use and upgrades. Free-license users can use the help center; paid technical services are available.
