The README for the parent repo (https://github.com/arxanas/git-branchless https://github.com/arxanas/git-branchless) answers these questions in detail. Short answer, recreating this tool's features in vanilla git requires using the reflog, which isn't user-friendly: > Why not git reflog? > git reflog is a tool to view the previous position of a single reference (like HEAD), which can be used to undo operations. But since it only tracks the position of a single reference, complicated operations like rebases can be tedious to reverse-engineer. git undo operates at a higher level of abstraction: the entire state of your repository.
