Agilefant is a simple but powerful solution for managing software development projects and related activities. It brings together the perspectives of organizing daily work, long-term product and release planning and project portfolio management.
Agilefant is an open source backlog management tool enhanced with hierarchical requirements handling capabilities. Agilefant provides three different planning levels for backlog management: product, project and iteration backlogs. Besides traditional flat-list backlogs, requirements can be expressed in tree form, in order to maintain traceability and transparency.
In addition to backlog and requirement management, Agilefant contains different composition views to the items in different backlogs, which can be useful for small to mid-sized development organizations. These composition views include time tracking features, personal work management and portfolio handling.
