This is online tool monitoring linux package repositories. It regularly fetches package updates a compares them between various linux distributions. This let's you compare versions of each package, it's dependencies a latests changes. I also fetches manpages defined in packages, as well as applications and some other useful details.
Only several major distros included so far, but more are coming soon.
This tool aims to compare current stable versions, LTS releases and future or in-development releases. Also, only amd64 versions are included at this time.
If you have any feedback, bug report, feature suggestion etc., please let me know.
