What are some modern, language agnostic CLI to manage multiple Git repos

I have used git repo (which is made popular by the android open source project) and I have also used git submodule to some limited extent. I find git submodule unnecessarily complex. git-repo, on the other hand, seems to be a bit dated. The original version for AOSP is written in Python and can be sluggish. There’s a re-written version in Golang by a team in Alibaba but it is not at feature parity compared to the original one. What do you use for your day-to-day multi-repo management and what would you recommend?
