##Why use Gramps? - 10 good reasons
Free and Open Source
Gramps is a free and open source, community project. It is freely distributable under the GNU General Public License which means you can freely use it, copy it, share it and even change it.
Full Unicode support
Language is not a barrier for Gramps. Whatever script you use Gramps offers full Unicode support. In other words, characters for all languages are properly displayed!
Rich set of tools
Gramps offers a rich set of tools. Research and analysis tools such as event comparison, finding duplicate people, interactive descendant browser, relationship calculator, data filtering, as well as tools for checking the database for errors and consistency.
Powerful graphs
With Gramps you have remarkable control over the produced graphs. You can define the family lines or even the individuals you want to include to portray relationships and you can create complex diagrams in the desired size and orientation, depending on your particular chart printing needs.
Wide variety of reports
Graphical reports can present complex relationships easily. Text reports such as individual and family reports as well as detailed ancestral and descendant, kinship, database summary and anniversary reports are amongst the many available options. You can combine them into a single ‘book’ format. You can even export your family tree to a fully operational web page in a snap and share it with your relatives!
Translated in many languages
So, you don't speak English? No problem! Volunteers have translated Gramps into more than 25 languages.
Expandability
Gramps’ open architecture allows the use of addons to give you more tools to work with your genealogy data. There are plenty of third-party plugins to enhance the program’s functionality which may not be officially part of Gramps. Find the right ones for you or make a feature request to the developers.
