Alioth is a FusionForge system run by the Debian project for development of free software and free documentation, especially software or documentation to do with Debian.
Most of the projects hosted by Alioth are packaging existing software in the Debian format. However, there are some notable non-Debian projects hosted, like SANE project.
History
Alioth was announced in March 2003. Originally Alioth was to be hosted on the SourceForge code base; the Free Software version of GForge was chosen later as it avoided the need to duplicate effort spent on rebranding SourceForge. Since 2009, Alioth runs a GForge descendant called FusionForge.
Alioth administrators include Raphaël Hertzog and Roland Mas.
