I think GitPlex meets most of the requirement here if you are writing Java code (and more languages are being added). Unlike other tooks, it does not place any requirements on project build system (Maven, Gradle, etc) and can work on any project containing supported languages.

I actually created this tool to suffice my own needs when browsing history of QuickBuild source code.
