Pros
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 Cross platform
It has native Linux, Windows and Mac clients.
Pro Free
As of version 0.38.2 there is no paid features or license.
Cons
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 Limited features
As it is in a new application in development it has a limited feature set if you are a power user.
Con Not open-source
Developer has shared the UI components to GitHub but not the source code of the application.
