GeneWeb is a genealogy software program with a Web interface originally developed by Daniel de Rauglaudre, but currently maintained by fabien@geneanet.org. It can be used off-line or in a Web environment. It uses very efficient techniques of relationship and consanguinity computing, developed in collaboration with Didier Remy, research Director at INRIA. Feel free to enable option GTK2 to try the new GUI. It's only disabled by default to avoid accidental GTK2 dependencies.
