About
The Sahana Software Foundation (SSF) has been building open source software for humanitarian situations for over 15 years.
The first Sahana software was created in Sri Lanka to help coordinate the response to the 2004 Tsunami. Since then, SSF software has been deployed in over 30 countries by dozens of groups ranging from national governments, international NGOs, UN agencies and grassroots networks.
As a nonprofit, community-driven free/libre/open-source software project, the SSF’s success depends on the contributions of passionate and enthusiastic people.
