For a single author you don't necessarily need any server at all. A cloud directory or zip files work well.

But gitolite is so easy to setup & maintain, it's not a big difference and for r/w-access management within teams, it's priceless.

I guess one could even hack anonymous access with "PermitEmptyPasswords yes" and "AuthenticationMethods none"

No Gitolite requires keys.

Hence "hack". It needs keys for administration but at a first glance, I see no reason why a git-anon user couldn't be part of gitolite's git user.
