Discover Concrete CMS

More than a CMS


Concrete5 - is one of the most modern open source enterprise content management systems (CMS), with which websites and web portals can be conveniently managed, expanded and edited.

Concrete5, a CMS that focuses on simplicity and stability

Many content management systems make life difficult for editors and site operators. In order to deal with these complex and often not very intuitive CM systems, a long training period is usually necessary, which not only costs nerves but also money.

Concrete5 offers a simple content management environment for those who don't want to waste time or money. The concrete5 system is equally suitable for small and medium-sized websites as well as for large sites with many millions of visitors per day. At the same time concrete5 shines through user-friendliness, high performance and comprehensive functionality.

We - Xanweb GmbH - are specialists for concrete5, because we know its architecture down to the last detail. We have been implementing complex web applications based on this system for many years. We are so convinced of its strengths that we are community leaders of concrete5 and work in the beta team of the system. Since 2008 we also run the German side of concrete5.
