Our community builds open source tools to help people prepare for and respond to disasters.

The first version of Sahana was created in Sri Lanka to help coordinate the response to the 2004 Tsunami. Since then it has been deployed in over 30 countries by dozens of groups ranging from large international NGOs such as Internal Federation of Red Cross (IFRC) to grassroots networks such as Occupy Sandy.

As a nonprofit, community-driven free/libre/open-source software project, Sahana’s success is dependent on a vibrant community of passionate and enthusiastic people.
