Companies sponsoring development

The following companies are investing substantially in the development of the XWiki project and they all have at least 1 active core Committer in the project (see XWiki.org governance for details). If you wish to help the XWiki open source project develop and improve you should consider buying something from these companies:

Open source projects used by XWiki

In addition, XWiki uses lots of other open source projects. Without them it would have taken tens of years to make XWiki from the ground up. XWiki is standing on the shoulders of giants! Thanks very much to all of these projects and the people/companies behind them.

XWiki Community

Thanks also to all the XWiki users out there who are making it worthwhile to develop XWiki.
