A little over a year ago, we began developing a new platform with a flexible plugin based architecture called Allura. The platform was created from day one with openness in mind. It was developed using open source technology like Python and MongoDB, to host open source software, and was build to be an open platform that could be easily extended by the community.

To go with this new Allura platform, we created a default set of tools including a tracker, forums, a wiki, and code hosting. Today, we are proud to announce the open source release of Allura and the related tools under the Apache 2 license.

Allura includes a customizable ticket tracker, wiki, discussion system, git, mercurial, and subversion.
