Kunstmaan Agency has created a number of Symfony2 Framework Bundles to enable developers to create web applications with CMS features. It's not a complete product in itself, but offers flexibility for skilled developers to create easy to use site experiences for content creators.
Kunstmaan has been working on the Symfony Framework for a long time and their extensive collection of CMS bundles power a large number of websites.
The functionalities built by the Kunstmaan team includes an integrated Dashboard for quick overview of how the site is doing. In addition to a CRUD style content editing experience, the system includes a tree menu editing tool, media management, versioning and permissions and more.
Developers well versed in the Symfony Framework can take advantage of the Rapid Application Development (RAD) toolkit that allows developers to quickly generate snippets of code to avoid manual work.
