jj-vcs

The jj-vcs organization develops Jujutsu, a Git-compatible version control system written in Rust. The project was started by Martin von Zweigbergk (Google) as a hobby project in 2019 and has grown into a full-time effort with multiple Google contributors. Jujutsu combines ideas from Git, Mercurial, Sapling, and Darcs into a single CLI tool with a novel working-copy-as-commit model and first-class conflict handling. The project is open source under Apache 2.0 and community-supported.
