Ushahidi is an open-source PHP platform hosted on GitHub that enables crisis information crowdsourcing, allowing individuals to submit reports via text messaging, email, or web forms. Originally developed to track violence during Kenya's post-election unrest in 2008, it has been utilized for various purposes, including monitoring elections in Mexico, tracking Swine Flu outbreaks, and addressing medical supply shortages in several African countries. Ushahidi aggregates and visualizes data from individual reports, such as text, photos, or videos, to provide quick insights during crises or events. The platform supports further development through its API, as well as iPhone and Android apps, inviting contributions from developers through a developer wiki, direct contact with the team, or GitHub pull requests.
