Herdr: One terminal to rule them all
Herdr introduces itself as a terminal multiplexer specifically engineered for the modern workflow of managing multiple AI agents. It aims to offer a more agent-aware and mouse-friendly experience than traditional tools like tmux or Zellij, emphasizing persistence and remote access. Hacker News users are intensely debating whether these tailored features provide enough distinct value to justify adopting a new tool in a space dominated by long-standing, highly customizable alternatives.
The Lowdown
Herdr presents itself as "one terminal for the whole herd," a binary agent multiplexer built for developers managing multiple AI agents across different environments. It aims to bridge the gap between traditional terminal multiplexers and agent-specific GUIs, offering persistence, remote access, and agent state visibility without the bloat of an application.
- Agent Orchestration: Designed for running multiple coding agents (e.g., Claude Code, Codex) from a single terminal, even over SSH, maintaining their state regardless of connection.
- Persistence & Remote Access: Agents run on a server and persist even if the local terminal closes; users can reattach from any device, including phones, thanks to its responsive TUI.
- Mouse-Friendly TUI: Features a responsive terminal user interface with clickable panes, tabs, and workspaces, enhancing usability compared to keyboard-centric multiplexers.
- Agent-Aware State: Provides at-a-glance status (blocked, working, done, idle) for individual agents, a key differentiator from generic terminal multiplexers.
- Integration & API: Supports integration with existing agents and offers a CLI and JSON socket API for programmatic control and community plugins.
- Minimalist Design: Emphasizes being a lean binary, not an Electron app, with no account requirements or telemetry.
Herdr positions itself as an evolution of the terminal multiplexer, tailored for the emerging workflow of interacting with multiple AI agents, offering a blend of traditional terminal power with modern agent management features.
The Gossip
Multiplexer Musings: Herdr vs. the Classics
The most prominent discussion revolves around Herdr's differentiation from established terminal multiplexers like tmux and Zellij. Users question if Herdr offers enough novel value beyond agent status and mouse-friendliness to warrant a switch, arguing that many features can be replicated or already exist in alternatives. Proponents, however, highlight its opinionated, agent-centric design as a significant workflow improvement, particularly for managing numerous AI processes.
Corporate Credibility Concerns
The "Popular with engineers from..." section, featuring several large tech company logos with the disclaimer "Individual engineers, not company endorsements," sparked a cynical debate. Commenters universally recognized this as a common marketing tactic, with many expressing skepticism about the genuine endorsement implied by such lists, even with the explicit disclaimer. The discussion touched on the fine line between valid marketing and perceived misrepresentation.
Agent Orchestration and Worktree Woes
A significant portion of the conversation centered on Herdr's utility for managing AI agents and its interaction with `git worktrees`. Users shared their challenges with scaling agent workflows using traditional tools and expressed enthusiasm for Herdr's ability to provide visibility and persistence for multiple AI processes. The integration with `git worktrees` for parallel development, including agent-assisted merging, also garnered attention, with practical advice and alternative solutions discussed.
