TypeGenealogy software

Gramps (formerly GRAMPS, an acronym for Genealogical Research and Analysis Management Programming System)[2] is a free and open source genealogy software.[9] Gramps is programmed in Python using PyGObject. It uses Graphviz to create relationship graphs.

Gramps is a rare example of commons-based peer production[10] as free and open-source software created by genealogists, for genealogists.[10][11] It has been described as intuitive[11] and easy-to-use[12] for hobbyists and "feature-complete for professional genealogists".[11] The program is acknowledged as the "most popular FOSS program for genealogy" by Eastman[11] and others.[12] The Australian consumer advocacy group, CHOICE, has recommended Gramps.[13][14]

The program is extensible such that, in addition to human family trees, it has been used to create animal pedigree charts[15] as well as academic genealogy showing mentoring relationships between scientists, physicians, and scholars.[16]


Gramps is one of the biggest offline genealogy suites available.[17] Features include:

Container forGramps XML and referenced media

The core export file format of Gramps is named Gramps XML and uses the file extension .gramps. It is extended from XML. Gramps XML is a free format. Gramps usually compresses Gramps XML files with gzip.[27] The file format Portable Gramps XML Package uses the extension .gpkg and is currently a .tar.gz archive including Gramps XML together with all referenced media. The user may rename the file extension .gramps to .gz for editing the content of the genealogy document with a text editor. Internally, Gramps uses SQLite as the default database backend, with other databases available as plugins.[28]

Gramps can import from the following formats:[29] Gramps XML, Gramps Package (Portable Gramps XML), Gramps 2.x .grdb (older versions Gramps), GEDCOM, CSV.

Gramps supports exporting data in the following formats: Gramps XML, Gramps Package (Portable Gramps XML), GEDCOM, GeneWeb's GW format,[30] Web Family Tree (.WFT) format,[31] vCard, vCalendar, CSV.

Programs that support Gramps XML


Gramps is available in 45 languages[7][37] (December 2014).

Gramps also has two special use sub-translation languages:
