Gramps (formerly GRAMPS, an acronym for Genealogical Research and Analysis Management Programming System) is a free and open source genealogy software. Gramps is programmed in Python using PyGObject. It uses Graphviz to create relationship graphs. Gramps is a rare example of commons-based peer production as free and open-source software created by genealogists, for genealogists. It has been described as intuitive and easy-to-use for hobbyists and "feature-complete for professional genealogists". The program is acknowledged as the "most popular FOSS program for genealogy" by Eastman and others. The Australian consumer advocacy group, CHOICE, has recommended Gramps. More information...
