Composite C1 can be regarded as a CMS without database by default with an option of migrating its data store to a Microsoft SQL Server database. As the CMS without database it uses XML files for its data store.
Composite C1 development began mid-2007, it reached version 1.0 in January 2009 and until September 2010 was sold as a commercially licensed product, primarily to customers in Northern Europe.
On 29 September 2010, Composite released C1 version 2.0 as free open source software under the Mozilla Public License, pledging to continue development on the free core and providing paid services.
In October 2010, Composite C1 was added to the .NET 4 enabled parts of Microsoft's Web App Gallery (Web Platform Installer 3 and WebMatrix).
In March 2011, Composite C1 version 2.1 was released, making SQL Server support part of the open source project.
In December 2011, Composite C1 version 3.0 was released, improving on the developer and content editor user experience and adding ASP.NET Razor as a layout template technology option.
In January 2012, Composite C1 version 3.1 (called a "service release"), adding support for spell checking (when using Mozilla Firefox with dictionaries installed) and .less files.
In April 2012, Composite C1 version 3.2 was released, adding "Save and Publish" combo button, support for plugging in external media data bases (like SharePoint or images from Facebook), HTML5 video streaming. It is compatible with .NET Framework 4.5 and Visual Studio 2012.
In July 2013, more than a year since the last release, Composite C1 4.0 was released that is considered the 2nd big milestone release since Composite C1 open-sourced in October 2010, adding end-user features such as the block selector, searchable drop-downs, freehand image resizing, new Starter sites, as well as developer features such as built-in Razor and User Control functions, Razor and Master Page templates, page template features, data tree ordering.
In November 2013, Composite C1 version 4.1 was released, adding drag-and-drop for images and files from the desktop into page content, support for Composite Form Builder, Internet Explorer 11 support, a new "Static Datatypes" folder on the Data Perspective, a 100% customized UI for the "Function Call Editor" for custom C1 Functions, and many more.
In May 2014, Composite C1 version 4.2 was released, adding C1 Function previews in Visual Editor (showing an image of the rendered function rather than an abstract representation of "a macro"), simplified editing of C1 Function properties, a new responsive starter site called "Venus", iPad editing support, ASP.NET Razor 3.1.1 support and more.
In June 2014, version 4.2 update 1 was release, which contains a number of improvements and bug fixes. This release is a recommended update to version 4.2.

Composite C1 and Microsoft Azure
- on a web site
- in a cloud service
The administrative panel in Composite C1 is called the "C1 Console". It gives access to the backend via the so-called "perspectives", sections of the administrative panel that group the backend functionality of the specific purpose. There are 6 built-in perspectives:
- Content where websites, web site structures and web pages can be managed and edited
- Media where media files can be stored and managed
- Data where data types and data can be managed
- Layout where page templates can be created and managed
- Functions where additional functionality can be created by using ASP.NET Razor, XSLT, C# etc.
- System where other CMS-related functionality can be viewed and managed such as C1 packages, website languages, hostname configuration, the server log etc.
The perspectives can be extended with other functionality as well as more perspectives can be added to the C1 Console. Some C1 packages - when installed - are available from their own perspective, for example, "Extranet" or "Package Creator".
