Using OAuth, you can connect SmartGit with your accounts in Github, Bitbucket, or Stash and access the remote repositories there. You can then clone, fork, commit or push to your remote repositories from inside SmartGit. You can also view and manage pull requests for your open source projects from SmartGit.

Not every, but nearly all.

Compared to gitk, git gui, SourceTree, GitKraken.

GitFlow provides a consistent development process by defining a strict branching model that is great for managing large projects. SmartGit allows for setting up and integrating into repos that follow this model.

SmartGit has a rather clean and uncluttered user interface. All the most useful tools and information are displayed at all times or are otherwise just a couple of clicks away.

All repositories are displayed in the sidebar and through a tabbed interface you can view various info about a specific repository (files, branches, branch graph, etc). The most used git commands like pull, push, sync, commit and merge are always available on top.

SmartGit can be used free of charge by Open Source developers, teachers and their students, or for hobby, non-paid usage.
