Upsource

You've found the right code review tool. Tracks where par­tic­i­pants stand on each dis­cus­sion, en­sur­ing it won't dis­ap­pear un­til re­solved. Fully cus­tomiz­able logic de­ter­mines when a re­view is com­plete. Clearly shows net deltas since last time you looked, even if com­mits got re­based or amended. Batches com­ments and cor­rectly threads email re­sponses. Works only with GitHub and GitHub En­ter­prise, mak­ing for a seam­less in­te­gra­tion. Min­i­mal ad­min busy­work, no ex­tra fluff — just awe­some code re­views. In­stantly diff any two re­vi­sions of a file, in uni­fied or side-by-side style. Hide mi­nor changes: white­space, merge, and re­base deltas. Cus­tomize mar­gin, fonts, col­ors, key­board short­cuts, etc. Jump from a com­ment straight to the right spot in your fa­vorite ed­i­tor. Line com­ments map across file re­vi­sions and stay in place un­til re­solved, not just un­til changes are pushed. Mod­ern, clean UI with a touch of whimsy.
