Original: Herdr and the Throughput Case for Parallel Coding Agents
Short summary
Herdr is a terminal-based agent multiplexer — essentially tmux for coding agents — that runs multiple AI agents in real PTYs with persistent sessions, semantic state tracking, and a CLI plus socket API for programmatic control. It enables a supervisor pattern where one agent orchestrates helper agents for parallel engineering tasks like API changes, test updates, and deployment review. The socket API allows agents to start, monitor, and consolidate other agents' work.
- •Herdr is a terminal agent multiplexer giving each coding agent a real PTY with persistent sessions
- •Semantic state tracking shows whether agents are blocked, working, done, or idle
- •Socket API enables programmatic agent orchestration — agents can start and supervise other agents
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
