Ranked in these QuestionsQuestion Ranking
Pro Open Source, GPL-licensed
Pro Allows doing complex things without memorizing git
Git usage beyond basic checkout/commit is arcane; GitUp lets you do things in git in seconds that would take you a half hour of research with the command line.
Pro Full undo
You can backup, or edit commits, if you make a mistake.
Pro Blazing fast
Fast Git GUI. Everything is already there and loaded when you open up the window.
Pro Fast and easy to use
Pro Dark theme support
Pro Comfortable when staging line-by-line changes
This feature is superior to the one that is implemented by SourceTree as it does not reset the file scroll view to the top of the file after each stage.
If you do feature-specific commits after some time of development - it's very important to be able to easily compose the commit from different line-based changes.
Pro Comfortable keyboard shortcuts
Pro Highlights the difference within a line
Pro Free (as in free beer)
Good looking free Git client for Mac.
Pro Smart Diff is very handy
Con OS X Only
Only available for OSX, so if you are used to working with different OSes and you want the same tools in each of them, it's impossible to have that with GitUp.
Con Font size is not adjustable
Tiny font not good for those with poor vision.
Con Hard to see which repos have uncommitted changes at a glance.
Have to click the repo names one by one to see the uncommitted changes. Remember Sourcetree Mac client having an indicator showing the number of uncommited changes.
Con Still a young client, thus so not as feature rich
This git GUI client is quite young compared to industry old-timers like git-tower 2 or SourceTree. So it's not as feature rich as you'd like. Still a very capable client for a simple day-to-day work.
