Ushahidi, Inc. is a non-profit software company that develops free and open-source software (LGPL) for information collection, visualisation, and interactive mapping. Ushahidi (Swahili for "testimony" or "witness") created a website in the aftermath of Kenya's disputed 2007 presidential election (see 2007–2008 Kenyan crisis) that collected eyewitness reports of violence reported by email and text message and placed them on a Google Maps map.
The organisation uses the concept of crowdsourcing for social activism and public accountability, serving as an initial model for what has been coined as "activist mapping"—the combination of social activism, citizen journalism and geospatial information. Ushahidi offers products that enable local observers to submit reports using their mobile phones or the internet, while simultaneously creating a temporal and geospatial archive of events.
