Scoreboard
Scoreboard is a graphical visualisation console for monitoring projects. Unlike the swathe of continuous integrations tools which do everything, but nothing well, Scoreboard focuses on providing a rockin’, rock solid visualisation and feedback platform for individual and multiple projects. It aggregates and presents feeds from most of the current crop of continuous integration tools.
Keep your eye on the score!
