Ranked in these QuestionsQuestion Ranking
Pro Great GitHub integration
This is the official GitHub desktop client built by the GitHub team.
Pro Simple, streamlined GUI
GitHub Desktop uses an extremely simplistic two-panel view. It's not capable of complex historical visualisations like other GUIs, but it is very easy to use (especially for git novices).
Pro Supports pull requests
In addition to being able to seamlessly and easily integrate with all of GitHub's features, it also supports forking and submitting pull requests on any open source project hosted on GitHub.
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 Comfortable keyboard shortcuts
Pro Merge Conflict Resolution is great
Pro Smart Diff is very handy
Can't handle complex tasks. The Help Manual advises to use command-line Git instead.
Poster child for authors' programming ideology (FRP), likely the cause for the odd quirks and bugs it has.
Con Not free/libre
This application is proprietary, and thus cannot be modified or freely distributed.
Con Non-GitHub repositories are not fully supported
Since this is mainly a GitHub client, other repositories are not fully supported and with as many features and setting up a repo hosted anywhere else but GitHub is troublesome.
Con Does not support multiple Remotes for a repo
Only allowed to assign one URL as remote. To manage/sync/fetch other remotes, use command-line Git instead.
Con No Linux support
There's no Linux version of this client.
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.
