worktrunk

Worktrunk makes Git worktrees as easy as branches. A worktree is an extra checkout of your repo in its own folder, so several AI coding agents can work at once without trampling each other. Plain git worktree makes you type the branch name three times; wt switch -c -x claude feat creates both and launches Claude Code in one line. It's a free Rust CLI, dual-licensed MIT or Apache 2.0.

Nothing to host. Install it (Homebrew, Cargo, winget and others), then run wt config shell install so it can change directories. On Windows, wt collides with Windows Terminal, so winget also installs it as git-wt. It has outgrown a wrapper: lifecycle hooks, one-command squash and merge, LLM commit messages through whatever CLI you already use, CI status in wt list --full, and copy-on-write sharing of node_modules or target/ on APFS, btrfs and XFS. No paid tier: solo, small teams and larger teams all run it free.

The catch: it's pre-1.0 and churns. The October release listed 13 breaking changes across hooks, templates and config paths, so pin a version. It's essentially one maintainer. Project hooks in a repo's .config/wt.toml run shell commands; worktrunk asks first, but --yes skips the prompt.
