A kanban board is a way to visually depict work at various stages of a process using cards to represent work items and columns to represent each stage of the process. Cards are moved from left to right to show progress and to help coordinate teams performing the work. Kanboards traditionally used post-it notes on whiteboards, however these days many people like to use online versions.
Trello is one such product. It’s a web based one, and I used it for a long while. Recently, it’s been bought out by Atlassian, and as such, it’s become an expensive product. Kanboard is almost feature-compatible with Trello, and of course, in true open-source fashion, it’s free of charge. This article shows you how to install it on an Ubuntu machine.
