Ranked in these QuestionsQuestion Ranking
Pro Easy to use
Pro Comes with Git
Gitk is a part of the git package, so no additional application is necessary: it is developed right alongside git itself.
Pro Visibly more compact overview output than many other options
When using gitk to scan a long list of changes, the user is able to see more of the list without pagination, as there is no huge buffer of whitespace between each entry.
Since it's pretty minimalistic and does not contain a lot of features (for example, it can't commit), it's quite fast.
Gitk is a free and open source tool. It forms part of the official git suite.
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 Highlights the difference within a line
Pro Free (as in free beer)
Good looking free Git client for Mac.
Pro Comfortable keyboard shortcuts
Pro Smart Diff is very handy
Con Cannot commit
The user needs to use a different Git client (GUI or otherwise) to commit changes.
Con Does not automatically update
The user must press F5 to refresh the view as there is no automatic update available.
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.
