TypeGenealogy software

Gramps (formerly GRAMPS, an acronym for Genealogical Research and Analysis Management Programming System)[2] is a free and open-source genealogy software.[8] Gramps is programmed in Python using PyGObject. It uses Graphviz to create relationship graphs.

Gramps is an example of commons-based peer production[9] as free and open-source software created by genealogists, for genealogists.[9][10]

The program is extensible such that, in addition to human family trees, it has been used to create animal pedigree charts[11] as well as academic genealogy showing mentoring relationships between scientists, physicians, and scholars.[12]


Gramps is one of the biggest offline genealogy suites available.[13] Features include:

  • Supports multiple languages and cultures,[14] including patronymic, matronymic, and multiple surname systems.
    • Full Unicode support.
    • Relationship calculators.[15] Some languages have relationship terminology with no proper translation to other languages. Gramps deals with this by allowing for language-specific relationship calculators.
  • Generates reports in multiple formats, including .odt, LaTeX, .pdf, .rtf, .html, and .txt.
  • Produces a wide variety of reports and charts, including relationship graphs of large complex acyclic charts.[16]
  • Gramps can be extended via more than 10 types of plugins. The plugin types that supplement the interface are called Gramplets and Views. A Gramplet is a focused view of data that either changes dynamically during the running of Gramps or provides interactivity to your genealogical data in the broader main view.[17]
  • Gramps employs an explicit event-centric documentation approach, similar to the CIDOC Conceptual Reference Model used by many cultural heritage institutions.[18]
  • "Sanity check" flagging of improbable events, such as births involving people extremely young or old.[2]
  • Support for multiple calendars, e.g. Gregorian calendar, Julian calendar, Islamic calendar, etc.[19]
  • Complete programmer's API documentation with free and open-source code made publicly available.[20]

Core archival 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.[23] 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.[24]

Gramps can import from the following formats:[25] 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,[26] Web Family Tree (.WFT) format,[27] vCard, vCalendar, CSV.

Programs that support Gramps XML[edit]

  • Gramps Web is a collaborative web app built on the core of Gramps itself and supports Gramps XML import and export[28]
  • Betty by Bart Feenstra generates static websites from Gramps XML and Gramps XML Package files as alternatives to GEDCOM.[29]
  • PhpGedView (version 4.1 and up) supports[30] output to Gramps XML.
  • The Gramps PHP component JoomlaGen for Joomla uses an upload of the GRAMPS XML database export to show genealogical information and overviews. JoomlaGen is compatible with GRAMPS 3.3.0.[31]
  • The script tmg2gramps by Anne Jessel converts The Master Genealogist v6 genealogy software datafile to a Gramps v2.2.6 XML.[32]


Gramps is available in 45 languages[33][34] (December 2014).

Gramps also has two special-use sub-translation languages:

  • Animal pedigree which allows to keep track of the pedigree and breed of animals[35]
  • Same gender/sex which gives the option of removing gender-biased verbiage from reports.[36]
