Released under the General Public Licence, TaskFreak is a free and open source web based task management software written in PHP. You can setup TaskFreak with MySQL or SQLite easily, and order tasks by priority and deadline, organize by project and context.
TaskFreak is similar to a project management software but concentrated more on tasks and does not have features like milestones, files or messaging. This makes TaskFreak simple but efficient for task management.
