To be clear: You can also use your normal git CLI to interact with this git server. You don't need the web interface. That's just to make it more human-friendly and allow you to sign events with the browser extension. The whole thing is an API. The people and bots with write-access to the instance's default relays have full permissions. People and bots who can Nostr AUTH have public access, with mild rate-limiting. Everyone else is a guest and have to behave themselves. 😁
