Some other interesting tools in the space. Rust is using a tool called Josh to sync commits: https://josh-project.dev https://josh-project.dev The blog post from the Rust people: https://blog.rust-lang.org/inside-rust/2026/06/04/how-josh-helps-rust-manage-code-across-multiple-repositories/ https://blog.rust-lang.org/inside-rust/2026/06/04/how-josh-h... Meta used to have an open source tool called fbshipit. But according to its open source repo they no longer use it: https://github.com/facebookarchive/fbshipit https://github.com/facebookarchive/fbshipit Any others in this space?

git subtree was the OG tool: https://apenwarr.ca/log/20090430 https://apenwarr.ca/log/20090430 It has since been merged into git proper: https://manpages.debian.org/testing/git-man/git-subtree.1.en.html https://manpages.debian.org/testing/git-man/git-subtree.1.en... https://docs.github.com/en/get-started/using-git/about-git-subtree-merges https://docs.github.com/en/get-started/using-git/about-git-s...

  The rust blog post covers this. Subtree performance is terrible on larger repos and they didn’t land something that would fix it on medium sized ones. That’s why they went with a better maintained solution that scales.

    Plus Josh seems to do waaay more - dynamically exposing monorepo directories as a separate repo. I wish all the effort into things like JJ and Pijul was going into solving those sorts of things instead!

      Pijul natively handles monorepos btw, that's the whole point.

Yeah I vibe coded https://github.com/sluongng/capyfun https://github.com/sluongng/capyfun during a hackathon recently to add a generative transformation layer on top of the traditional imperative transformations.
