Jujutsu (jj) is a version control system designed to simplify common development workflows while remaining compatible with Git repositories. It approaches version control differently from conventional Git clients, particularly in the way it handles working-copy changes, commits and repository history.
Instead of requiring developers to stage and commit every change manually, Jujutsu automatically records changes to the working copy as part of its normal command workflow. Its design makes it straightforward to revise earlier changes without repeatedly managing Git’s staging area.
Jujutsu also maintains an operation history, allowing users to inspect previous repository states and undo mistakes. It can work with existing Git repositories and hosting services, making it possible to adopt its workflow without abandoning Git infrastructure.
This is free and open source software.
Key Features
- Git-compatible storage and support for working with existing Git repositories.
- Automatically snapshots changes to the working copy during ordinary commands.
- Tracks newly created files by default, while respecting configured ignore patterns.
- Operation log records changes to repository state and supports undo and recovery.
- Automatically rebases descendant commits when earlier revisions are rewritten.
- First-class handling of conflicts, allowing unresolved conflicts to be recorded and resolved later.
- Revision identifiers remain stable across many commit rewrites through change IDs.
- Flexible revision selection using revsets and configurable templates.
- Split, squash, abandon, restore and reorder changes without manually rebuilding commit history.
- Named bookmarks for tracking revisions and exchanging branches with Git remotes.
- Support for multiple workspaces sharing a repository.
- Customisable aliases, configuration and command output.
- Built-in diff display and integration with external editors and merge tools.
- Safeguards against accidentally rewriting immutable revisions.
- Cross-platform support for Linux, macOS and Windows.
