Worktree¶
A worktree is a Git feature that allows multiple working directories to be linked to a single repository. With git worktree add, a developer can check out a different branch into a separate directory without disturbing the current working directory.
This is useful when:
Working on a hotfix while keeping the main feature branch open
Running tests or builds on a different branch simultaneously
Comparing the current implementation against another branch side by side
CI/CD pipelines needing isolated checkouts from the same repository
Each linked worktree has its own index and HEAD but shares the object store with the main repository, avoiding duplication.
See also git-worktree documentation and A practical guide to git worktrees.
