It may be hard to believe, but Sakai is not the only collaboration, learning, or course management system. There are others including some that are commercially available, and other open source development efforts.
This section includes information on how Sakai compares to other systems. This is not intended to be a competitive analysis, but rather an informative one. Please add links or references to comparisons that you know of, or add additional information.
Have a look at http://www.edutools.info/course/
for more comparisons.
