Love at first site ...
Composite C1 CMS is a fully featured free open source web content management system developed for and by web professionals that focus on corporate websites.
The user interface is very functional and task oriented and enables users of varying skills to complete tasks and cooperate using familiar tools and guides. High-end technical skills are not a requirement to build websites with Composite C1, but if you've
got them, you will own the system, not the other way around.
Developers can manage layouts and extend the system using any choice of ASP.NET Razor, MVC, Web Forms and XSLT, and both back-end and front-end developers are highly empowered and able to control website look and feel down to minute detail.
Being based on .NET 4 developers have access to the latest technologies, a pluggable well designed architecture and API and full LINQ data access at their disposal. This is a flexible system with easy setup, easy Windows Azure migration, both file based
and SQL Server data support, a lot of free easy-to-install add-ons and a set of premium offerings (corporate website add-ons, support, upgrade services, full warranty licensing), which makes Composite C1 a scalable product, both in terms of price, service
and complexity.
A very strong emphasis on quality, documentation, flexibility and developer community. So far all major releases of Composite C1 have been voted “best CMS” at CodePlex.
