Contao
Open-source PHP content management system built on the Symfony framework.
Contao is a content management system built on the Symfony framework. One installation can run several websites, each in several languages, and editors share the administration area under detailed user permissions. The install guide sets it up through the Contao Manager’s graphical interface or with Composer on the command line, and the download page also offers it as a bundle for an existing Symfony application.
