Jujutsu
What Jujutsu is
Jujutsu is a free, open-source distributed version control system for software projects, available on Linux, macOS, and Windows under the Apache 2.0 license. It is intended for individual developers and large teams, supporting code copying, change tracking, and publishing. Its production-ready Git backend works with any Git remote, and Jujutsu commits appear as regular Git commits, allowing users to return to Git. Working-copy changes are recorded automatically as commits, so there is no explicit staging area. An operation log records repository actions and can undo operations or restore earlier states. Conflicts remain in commits, letting operations finish before resolution. Jujutsu can automatically rebase descendants after commit changes and supports editing, splitting, and moving changes between commits. Documentation covers GitHub, GitLab, and Gerrit workflows. Sparse checkout is supported, while submodules, partial clones, Git LFS, and nested repositories are not. Git 2.41.0 or newer is required at runtime.
Who it suits
Jujutsu suits developers and teams wanting Git-compatible version control with automatic snapshots, operation history, and history-editing tools. It may be less suitable where submodules, Git LFS, partial clones, nested repositories, or native email workflows are required.
What it does well
- Free and open-source under Apache 2.0
- Production-ready backend for any Git remote
- Automatic working-copy snapshots as commits
- Operation log supports undo and restoration
- Supports sparse checkout and history editing
What to know first
- Described as experimental
- Requires Git 2.41.0 or newer
- Submodule, partial clone, and Git LFS support unavailable
- No native email-based workflows
Verdict
Jujutsu combines Git compatibility with automatic snapshots, operation undo, and flexible history editing. Its experimental status and listed Git compatibility gaps should be considered before adoption.
