Ranked in these QuestionsQuestion Ranking
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.
Since it's pretty minimalistic and does not contain a lot of features (for example, it can't commit), it's quite fast.
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.
Gitk is a free and open source tool. It forms part of the official git suite.
Con Does not automatically update
The user must press F5 to refresh the view as there is no automatic update available.
Con Cannot commit
The user needs to use a different git client (GUI or otherwise) to commit changes.
