Looking at the source I don't think that's true -- it's using GitHub specific APIs to read/write files. It's not standard git so any remote wouldn't work, and the mechanics are more akin to a key-value store than git really.

Not to say you couldn't add a generic git protocol to this, just that that's not being done here.

> The protocol itself isn’t tied to GitHub and works with any Git remote.

> If GitHub ever decided this wasn’t an acceptable use case, swapping the remote would be trivial.

Nope.

From the README:

"GitHub is the only working write provider right now. GitLab, GitVerse, Gitea, Forgejo, and other git hosts are protocol targets for future adapters. Today they are not finished write adapters."
