Agent HerderScale from one Claude Code session to many

Open, manage, and coordinate multiple sessions across your terminal's own tabs. No tmux, no split panes — first-class native tabs.

Native terminal tabs

Each session is a real tab in your terminal — not a tmux pane or split. Scrolling, copy-paste, and keyboard shortcuts work exactly as you expect.

Start one session, then spin up more as your task grows. Run parallel agents on different parts of the codebase without leaving your workflow.

The built-in Claude Code skill lets Claude spawn sibling sessions, check their progress, and coordinate work across tabs.

Branch a conversation into a new tab with --fork-session. Try alternative approaches without disrupting the original.

Set flags like --dangerously-skip-permissions once in ~/.config/herd/config.toml and they apply to every session automatically.

Plain CLI output, composable in shell scripts, Claude Code hooks, and automation workflows.
