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.

If you don’t need the web gui stuff (and you shouldn’t for personal use) you can set up a git server using gitolite. Very easy to manage
