Most of the Web GUIs are designed for interaction/collaboration between multiple people, and are massive overkill for one person. Tools like gitk/git gui are more than enough to see what’s going on graphically.

If you want to install all the other stuff, that’s completely up to you, but a lot of people don’t seem to realise that the Web GUI stuff and command line are completely separate things, and you don’t have to install both of them.
