Explore your source, FishEye opens your source code repository to help you understand your code and keep tabs on the people who write it.
View user activity, track code changes, search and navigate through the guts of your repository — all from the comfort of your browser.
You’ll never look at Subversion, CVS, Perforce or Git the same way again!
