I am looking for tool that would display statistics about project health - how quickly maintainers reply to issues and pull requests, how long issues and pull requests are staying open.
Also, it would be useful to see long-term trends - is it regularly maintained? Or are maintainer(s) appearing only sometimes and disappear for months? In addition it would be nice to see "quick action hints" - like "issue #12 is open since 156 BC", "pull request #115 is without comment from maintainer since its opening 10 million years ago".
It may be a web app or desktop program for either Windows 7 or Linux.
I am pretty sure that I encountered project that would display this type of statistics but now I am unable to find it.
I am aware of Pulse but it is capable of displaying only short-term statistics (up to one month) and I am interested into long-term info, including trends.
