Ranked in these QuestionsQuestion Ranking
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 Great GitHub integration
This is the official GitHub desktop client built by the GitHub team.
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 Smart Diff is very handy
Pro Free (for the moment)
The majority of work on Fork is done in the developers' spare time and, despite requests from the Fork community (who are keen to support the app), the product is still free. The developers are open about the possibility that they might make it a paid app at some point in the future, but the price is expected to be low and it will not be on a subscription basis.
Pro Merge Conflict Resolution is great
Pro Tabbed interface
Several repos can be open at once in individual tabs, so it's trivial to switch back and forth between them.
Pro Overall aesthetic
The GUI components are flawless on the Mac. It is expected to be a similar experience on Windows. Once you realize that you can filter by branch, your appreciation for the product will go up dramatically.
Pro Comfortable keyboard shortcuts
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 No Linux support
There's no Linux version of this client.
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 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 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.
Con Requires granting access to your git projects for the developer of the app
Con No Linux version
This git client is not compatible with Linux making the life harder for the developers that work on both, MacOS and some Linux distro.
