We primarily use this for repairing a broken Git repository. I don't usually use it and others on the team, as far as I know, don't necessarily use it in the normal workflow, but it is pretty good when you have really messed up your repository. It lets you dive in visually and see what you've done. It's better than the command line tools.

We use Atlassian SourceTree to manage source code from different environments. It helps us merge all the codes by developers.

I installed Atlassian SourceTree on my Windows or Linux computer and I use it for check-in and check-out code, instead of going directly to the server and doing it that way. Atlassian SourceTree is a client-side application that interfaces with the Bitbucket server.
