Herdr is tmux for coding agents

Short summary

Herdr is a terminal multiplexer designed specifically for AI coding agents, tracking agent state (working, blocked, done, idle) rather than just displaying stdout like tmux or Zellij. It runs as a lightweight binary with no Electron shell or telemetry, keeping real PTY sessions alive across disconnects and enabling remote reattach. The core value proposition is parallelism: run N agents on independent tasks and spend human attention only where decisions are needed, with a CLI and socket API for programmatic orchestration.

• •Agent-aware terminal multiplexer that tracks coding-agent state beyond raw stdout
• •Supports parallel agent workflows with persistent PTY sessions and remote reattach
• •CLI and JSON socket API enable automated pane creation, prompting, and state-waiting

Generated with AI, which can make mistakes.
