Savane is a free web-based software hosting system, best known as the hosting software for the GNU Project's Savannah websites.
The GNU Project's Savannah website started out using SourceForge as its hosting software. However, after Savannah was set up, SourceForge was changed into proprietary software by its authors. The site's administrators at the Free Software Foundation forked the software in order to maintain it.
This software fork was originally called simply Savannah, since it was the software running the GNU Project's Savannah website and had no other name. It was later renamed Savane, the French word for "savannah", to distinguish the software itself from the websites, such as the GNU Project's Savannah, that use the software.
The software is currently being rewritten using the programming language Python, the Django web framework and CSS.
