A Git-compatible VCS with a commit-centric workflow
Jujutsu (jj) is an open-source version control system written in Rust. It aims to make the everyday VCS workflow simpler while staying compatible with the Git ecosystem. The key design is a working copy that is automatically committed: every file change becomes a snapshot you can revisit or revert. An operation log records every state mutation, providing robust undo/redo. Conflicts are first-class data objects instead of inline text markers, making merges and rebases more predictable. jj can be used in existing Git repositories or as a standalone VCS, so it supports incremental adoption. This project is relevant for engineers exploring modern VCS design, Git workflows, and high-quality Rust-based tooling.
