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.
