For the last 5(?) years or so I have been using GitKraken as my daily git driver for a while. I use it at my job mostly and love the functionality. I still use git via command line but jumping into git bash is nice no matter what os I am currently using.
I mainly use it:
To see what branches have been modified (same as git tree but updates itself).
Hooks into other git hosting like codeberg/gitea/forgeo without any real work. Login is also super easy and built in. Oauth is built in.
Git amend is a one click interface.
There is other niceties like issue tracking, easy auto-creation of branches, etc... that I personally don't use all that much, but I can see the appeal.
The only real issue is the price. It used to be 30$ a year but now it's over 100+. I would happily pay 30 a year or pay one time for a license...but over 100 is too much in my opinion. I may go back to using all command line if the price keeps going up.
Is there any open source tools that do something similar it's the same look/feel?
I've recently switched from Windows to Linux and generally I'm using Lazygit on the terminal or SourceGit on the desktop. SourceGit is by and large a very similar UI to Sourcetree but faster (and open source / cross platfrom)
