Thanks, hadn't heard of this one.

Looks a bit heavy though for my liking but maybe they have some good ideas.

> Copybara requires you to choose one of the repositories to be the authoritative repository

Looks like it is more angled at mirroring private to public.

Disclosure: I work at Google, but not on Copybara.

I've seen Copybara used at Google in both directions: for some projects, the internal repo is the authoritative one, and for others, the external repo is authoritative.

Copybara is not prescriptive, you can go in either direction.
