Git Worktrees Let You Run Parallel Claude Code Sessions Without File Conflicts

A developer explains how running multiple Claude Code AI sessions on the same file checkout causes conflicts, with changes from one session overwriting or clashing with another. The solution lies in Git worktrees, a long-standing Git feature that gives each session its own working directory and branch while sharing the same repository history. Using the '--worktree' flag in Claude Code automatically creates a dedicated directory and branch per session, allowing two sessions to commit independently without interfering. The author notes two practical limits: tasks must be genuinely independent of each other, and managing more than two concurrent sessions becomes counterproductive due to context-switching overhead. A few housekeeping steps, such as adding the worktrees folder to '.gitignore' and copying necessary ignored files like '.env', are recommended for a clean setup.
