Report: Open Source CMS Market Share 2009
Following on the heels of the 2008 Open Source CMS Market Share Report, this year we collaborated with water&stone to produce an improved 2009 version. The report is an interesting study of 20 dominant systems in the market. It's really not about which CMS is best, nor about relative comparisons beyond brand strength, sentiment and adoption patterns. We're aware of this.

Traditional and Social Media Analysis

What the study did was sniff around the nooks and crannies of our increasingly electronic and publicly broadcast lives and endeavor to quantify the relative brand strengths, brand sentiments and adoption patterns for the top 20 most popular content management products. In addition, we ran a survey on a little ways back. With this tool we were able to directly pose questions to our readership -- and more than 1200 of you took to the task (thank you!).

This year's analysis looked at Alfresco, CMS Made Simple, DotNetNuke, Drupal, e107, eZ Publish, Jahia, Joomla, Liferay, MODx, OpenCms, phpWebSite, Plone, SilverStripe, Textpattern, TikiWiki, Typo3, Umbraco and WordPress.

Key Conclusions: 3 Dominate, Many Are Vibrant

What jumped quickly out is that The Big Three -- Joomla, WordPress and Drupal -- led the survey set across a wide range of measures. However, the top slots are not static, Joomla has gained market share over Drupal, and WordPress with its hosted version has what looks like a smoother path to adoption.

The report identifies less obvious stars. Alfresco, a vendor focused on both document management and web content management, performed well across a number of categories, and led the Java-based open source CMS race over its nearest rival, Liferay. DotNetNuke led the .NET-based open source CMS category, though Umbraco is up and coming.

The report goes on to identify reasons why DotNetNuke's position may soon be changing. In addition to naming the market leaders, the study identifies projects whose market share and brand metrics indicate they are at risk or facing a closing window of opportunity. A metric we found of particular interest was the product evaluation rates versus the adoption rates.
