https://git-scm.com/docs/git-http-backend this is the official original git web, there's other tools associated with it, i didn't use it because they all insist i have to use apache and i hate apache

and as i mentioned, you can see https://mleku.net/legit this is a slightly improved version of a pure Go git http solution, i only needed the http git transport but it gives you a bare website as well... several features don't work but idgaf it's better than dealing with apache
