Git worktrees and Git branches are related but fundamentally different in how they let you interact with your code. Both are part of Git, but they solve different workflow challenges.[2][5]
Branches are Git's way of diverging from the main line of development to work on different features or fixes. In standard Git branching, you work in a single working directory and switch between branches using commands like git checkout or git switch. When you switch branches, Git updates the files in your current directory to match the branch you're switching to. This means you need to either commit or stash your work-in-progress changes before switching, which can disrupt your workflow.[1][5][2]
Git worktrees allow you to check out multiple branches from the same repository simultaneously, each in its own separate working directory. Instead of switching branches by changing what's checked out in one directory, you switch branches by literally moving between different d
