Composite C1 4.1 continues the stability and quality of the previous versions and provides more comfort to editors with new drag and drop features for media handling and building online forms. The Open CPH Starter Site Open is updated to Bootstrap 3.0 and offers a good starting point for every website project.

An excellent piece of software for both developers and users. Extremely easy to install, Intuitive UI for content managers. Performance of the sites is very good. Our dev team has tried several CMS's (including paid up ones) to combine MVC web app funtionality with a traditional CMS and this is by far and away the best one we have come across. Forum response to queries is also excellent. Well done

Tried out a few of the CMS applications here, and this seems to kill the rest of them by far! I am working my way through getting C1 CMS Certified!

A fantastic app/CMS. It has great layering so you don't need to be an expert to start... and then as you build your knowledge can switch to more complex developer's languages like C#. Combine this with MVC, Razor and you have a cutting-edge ready to use platform that is simply a joy to work with.

The best .NET CMS that I have seen !!! Nice to see it's possible to have a .Net CMS with all the basic functions (and more) but without the need to have expensive SQL hosting. Simple to use and to customize !

An excellent CMS and application platform. The beauty of it is the layering. It has items for all levels and as you learn it, more of the power opens up for you. From beginner to seasoned .Net professional, this CMS allows you full control of your angle brackets and enough power to fulfill even stringent demands. In addition, with the ability to run off XML or a database, it's easy to cheaply host

An outstanding body of work. This is not a CMS... this is a web development platform. Outstanding extensibility and really well designed interface and architecture by a team who obviously care about making something right. Key features for me are MVC3 integration and the reflection/compilation + consistent interface programming model but it's a mod steep learning curve and requires full trust.

Compare to other existing Content Management Systems, C1 CMS uses the edge technology such as MVC2, LINQ, Workflow. It is easy to use for the site administrators and developers. Now Web - matrix, I just have to say well done CompositeC1 CMS team, great job, great App.

I manually upgraded my 2.0 SP1 website to 2.1.1. - followed the upgrade guidelines and within 15 minutes everything worked perfect! That's the way how updates should work :-) Quality is the best description of C1 CMS - and for me the most professional and flexible .NET Open Source CMS.

Few months ago our team got a task to build a web site for certain customer. It was supposed to be small site, so we searched for something simple without database overkill as the backend... Then we found C1 CMS... Rest is history... But will be future... This is not only CSM, but framework/platform modular, easy to learn and stable. Our team has searched for a while to find CMS that does not overkill with database backend, but leaves this as an option.... Great.... Visual Editor is getting better and better... Just love v.2.1 and package creator...

Composite from Denmark is in the driving seat when it comes to application development via .NET
Oct 2010, Microsoft
УWhat Composite is doing is an extremely exciting, quite unique project. First and foremost it makes good sense to open up the source code of a .NET-based product, because there are already plenty of developer resources out there who will be able to carry the solution still further. That alone makes .NET an obvious choice as a developing platform in the open source contextФ.
Ole Kjeldsen, Microsoft.
"If you are into Windows Azure and now considering running some CMS on it, let me share good news with you. A .NET Framework-based CMS called C1 CMS has totally gone Windows Azure."

"C1 CMS is layered in a way that allows you to get up and running fast and still be as technical as you please".
MSDN UK Team blog
"Composite has enjoyed success with its CMS tools, which it supplies to major private and public clients as well as smaller companies. These days it uses .NET for its evelopment platform: indeed, Composite has succeeded in using it in such innovative fashion that the companyТs efforts have drawn attention deep inside the central .NET developer group at Microsoft headquarters in Redmond, Seattle."
