Git(hub) Client/GUI online

Hi,

i'm searching for a Git GUI/client to manage my Git Repo on my own Server. Currently i'm developing on my server in the browser with the Cloud9 IDE from AWS. So my whole dev environment is online/on my server.

But i can't manage the git repo on my server with ease as for example with Github Desktop or Tower.

Is there any solution for a Git(hub) GUI which i can access through my browser?
