## What it is
Herdr is a Rust-based terminal multiplexer and runtime designed for running AI coding agents like Claude Code, Codex, and Cursor in persistent terminal panes. It tracks agent state (working, blocked, idle), survives disconnects and restarts, and exposes a CLI and socket API so agents and scripts can orchestrate each other.

## Use cases
- run multiple AI coding agents in parallel terminals
- keep coding agents running after closing laptop or losing network
- monitor which agent is blocked or idle across workspaces
- let one agent spawn and coordinate other agents
- detach and reattach terminal sessions over ssh
- replace tmux with a mouse-first multiplexer
- restore terminal layouts after a server restart

## When to choose
- you run several AI coding agents (Claude Code, Codex, Cursor, etc.) simultaneously and need visibility into their state
- you want agent sessions to survive lid close, network drops, or machine restarts
- you need programmatic/agent-driven orchestration of terminal panes via CLI or socket API
- you want tmux-style keybindings plus first-class mouse interaction
- you want a single Rust binary with no Electron dependency

## When to avoid
- you only ever run one terminal with no AI agents and are happy with tmux
- you need full process preservation across full server restarts (snapshot restore only restores layout)
- you rely on niche agents not in the supported list and need deep lifecycle integration
- you need mature Windows parity — Windows support is newer with documented platform-specific gaps
