Ranked in these QuestionsQuestion Ranking
Pro Blazing fast
Fast Git GUI. Everything is already there and loaded when you open up the window.
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 Open Source, GPL-licensed
Pro Comprehensive interface
This application is FOSS, and thus it can be freely modified & distributed.
Pro No registration at all
Doesn't require registration to use.
It comes with many plugins and you can build your own. Included by default are some very neat visualization tools for Repository metrics.
Pro Easy to add add action in the GUI
Right click to add a script to delete remote branch or tag...
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 Poor UI
Rich developer experience but awful interface.
