Is there a Github clone that I can run on my own server?
Can i use Git without GitHub's service? What i mean is, i am only the person working on the project and don't want to push the project into the Git space. What do you think? Will this be a right decision? Or is there any lite github like server application available for internal use? Please share your thoughts.
Yes, git is independent of GitHub. If you push your source to GitHub the with a free account your project will need to be 'public' meaning anyone can read it. Other companies offer free private git repositories (I use Assembla). But you can actually use git without any server as well, to maintain local version control. This is definitely good practice anyway. A server would give you the added advantage of off site backup.
