Kanboard is a project management open source software application that uses a Kanban board to implement the Kanban process management system. Features include a minimal drag-and-drop web user interface, a command line interface and ability to automate repetitive tasks. It can help both agile and DevOps teams establish order in their daily work.
The Kanban board is the best way to know the current status of a project because it's visual. It's very easy to understand, there is nothing to explain and no training is required.
