XPlanner, another open source Agile project management software / tool, ranks among the earliest web-based Agile project management tools and is noted for its wide range of features while still retaining a simple planning model.
XPlanner supports recording and tracking projects, iterations, user stories, and tasks. It models itself along the eXtreme Programming (XP) process of decomposing stories into tasks, analyzing the project through completion of tasks, and in the end, collating all stories to complete the project.
XPlanner displays tasks and story statuses for developers and customers, with the facility to attach notes to stories and tasks, and generate distributed and integrated tokens with email notifications. The TWiki-style text formatting supports external tool integration and linking to Wikis.
XPlanner comes with an integrated online time tracker that generates both individual and team time sheets. Other highlights include the different charts for iteration velocity, Scrum burn down, distribution of task types, dispositions, and more, the facility to generate metrics such as team velocity and individual hours, and the facility to export such project and iteration information in XML, MPX (MS Project), PDF, and iCal formats
A major limitation is the requirement of knowledge of Java to set up the application.
