trac - project tracking tool
I took a close look at Edgewall Software’s trac tool today. It’s an integrated bug-tracker, wiki, Subversion repository browser and general project goal management tool, all available in a single web interface. It’s open-source and free for anyone to download.
The tight coupling of all the services seems to be a major win for this tracking tool. All of the components are aware of changes in the other components and can react appropriately. This is apparent in the timeline view that picks out changes from all the modules and puts it into a single project overview.
