A Rust-based tool I've been working on for a bit now, since getting hooked on the stacking workflow at work (we use Graphite mostly).

I didn't like the idea of getting married to a paid product for something so core in my day-to-day work, and other tools I explored (git-town, branchless, jj, spr, etc.) all had elements I didn't like, so I designed and built something for myself. I have tried to refine and expand it into what I think is a very polished tool that aims to work well on Linux, macOS, and Windows, with strong GitHub and GitLab integration (perhaps more eventually).
