BigVisibleWall is a simple Scala-based Web Application for displaying the status of (potentially) multiple builds. Many CI tools provide detailed dashboards which are useful for diving in to the details, but very few of them provide interfaces that work for the build monitors that sit in the corner of many development areas. Allowing you to customise the display of the screen, this simple embedded server is used by several projects at ThoughtWorks. If your CI server supports CCTray feeds, you can use BigVisibleWall.
BigVisibleWall is in need of some love – there are a number of feature requests that have built up for it. If you are interested in helping out, then drop me a line.
