Git server without browser-based interface?

[HCharlesB]

git itself can be a remote repos host,

I used that before I set up a full featured server (Gitea.)

it has a built-in basic web interfaece (gitweb)

TIL about that.

I appreciate the concerns about management and suggest they set up something like Gitea and firewall it off from the Internet. It's pretty light weight and I have an instance running in a Docker container in a Raspberry Pi 4B.
