overview

What is Herdr?

Herdr is a terminal-native agent runtime and multiplexer tool developed by Herdr that enables engineers, developers, and users of AI coding agents to manage multiple AI agents in parallel within persistent terminal workspaces. It provides real-time agent state awareness and an API for agents to use, streamlining complex AI development workflows.

Designed as a specialized alternative to general-purpose terminal multiplexers like tmux, Herdr integrates features specifically tailored for AI development. It allows users to spawn, monitor, and coordinate various AI coding agents, such as Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, Devin CLI, Pi, OMP, Hermes Agent, and Qoder CLI, within a single terminal interface. The platform ensures session persistence, enabling agents to continue execution even after terminal disconnections, and supports remote access via SSH.

features

Key Features of Herdr

Herdr provides a comprehensive set of features designed to enhance the management and orchestration of AI coding agents in a terminal-native environment. These capabilities address common pain points associated with running multiple agents simultaneously and maintaining session context.

Terminal-native agent runtime and multiplexer for AI agents.
Persistent terminal workspaces with detach and reattach functionality.
Real-time agent state awareness, displaying 'blocked', 'working', 'done', or 'idle' statuses.
CLI and Unix socket API for agent orchestration, allowing agents to drive Herdr.
Support for remote SSH attachment and thin-client access for agent sessions.
Mouse-friendly TUI controls, including panes, tabs, and workspaces.
Configurable UI elements such as ui.pane_borders and ui.pane_gaps.
Native Windows builds (beta) with ConPTY support for local persistent sessions.
Remote auto-updates for agent detection manifests and improved agent command discovery.
Single Rust binary architecture, typically around 10MB, for lightweight deployment.

use cases

Who Should Use Herdr?

Herdr is primarily designed for technical professionals who regularly interact with and manage multiple AI coding agents. Its features cater to workflows requiring parallel execution, session persistence, and real-time monitoring within a terminal environment.

Engineers and Developers: For orchestrating and monitoring multiple AI coding agents (e.g., Claude Code, GitHub Copilot CLI) in parallel.
AI Practitioners: For managing long-running AI coding sessions with persistence, ensuring work is not lost upon disconnection.
Remote Development Teams: For accessing and managing agent sessions on remote servers via SSH or thin-client support.
Automation Enthusiasts: For leveraging the CLI and socket API to automate agent fleet orchestration and integrate with custom scripts.
Users of Terminal Multiplexers: For those seeking a specialized alternative to tmux or Zellij with built-in AI agent awareness.

how to use

How to Use Herdr

Getting started with Herdr involves installation, launching the runtime, and then integrating or spawning AI agents within its persistent workspaces. The tool is designed for command-line interaction and offers both keyboard and mouse-friendly controls.

1Install Herdr via a package manager or by downloading the single Rust binary for your operating system.
2Launch Herdr from your terminal to initiate a new session or reattach to an existing one.
3Spawn AI coding agents within Herdr panes or tabs using their respective CLI commands.
4Monitor agent status (blocked, working, done, idle) through Herdr's real-time indicators.
5Detach from your Herdr session to allow agents to continue running in the background, and reattach later from any terminal, including via SSH.
6Utilize the CLI or Unix socket API to programmatically control agents, create new panes, or send input.

pricing

Herdr Pricing & Plans

Herdr operates on a freemium business model. While a free tier is available, specific details regarding paid tiers, features, or pricing figures are not publicly disclosed as of early July 2026. Users are encouraged to consult the official Herdr website for the most current pricing information and plan specifics.

Freemium: Basic functionality available at no cost.

Pros

+Provides persistent terminal workspaces, allowing agents to run continuously even after disconnection.
+Offers real-time, color-coded agent state tracking (blocked, working, done, idle), reducing cognitive load.
+Supports remote SSH attachment and thin-client access, enabling flexible development environments.
+Exposes a CLI and Unix socket API for advanced agent orchestration and automation.
+Lightweight and efficient, built as a single Rust binary (around 10MB), avoiding GUI overhead.
+Features mouse-friendly TUI controls and configurable UI elements for enhanced usability.

Cons

−Specific pricing details for freemium tiers are not publicly available, making cost planning difficult.
−Primarily terminal-focused, lacking a graphical user interface (GUI) option for users who prefer visual interfaces.
−May have a learning curve for users unfamiliar with terminal multiplexers or agent orchestration concepts.
−Relies on agent integration manifests, which may require updates for new or custom AI agents.
−While offering persistence, it does not inherently provide broader environment features like shared file systems or direct agent-to-agent communication found in some alternatives.

Similar Tools

Herdr vs Competitors

Herdr positions itself as a specialized terminal multiplexer and agent runtime, differentiating from general-purpose tools by integrating AI agent-specific features. It competes with both traditional terminal multiplexers and other AI agent management solutions.

Shire↗

Shire provides AI agents with persistent workspaces, including real filesystems, shared drives, and direct agent-to-agent communication, allowing agents to retain context and state across tasks.

Similar to Herdr, Shire emphasizes persistent workspaces for AI agents, but it focuses on a broader environment with shared drives and direct agent communication, whereas Herdr is a terminal-native runtime and multiplexer. Shire is open-source, aligning with Herdr's freemium model.

CLI Agent Orchestrator (CAO)On Stork Compare

CAO is an open-source, multi-agent orchestration framework that transforms how developers work with AI-powered CLI tools by running each agent in an isolated tmux session.

CAO directly competes with Herdr's multiplexer and agent runtime aspects by offering multi-agent orchestration and session isolation via tmux. While Herdr provides persistent terminal workspaces, CAO focuses on coordinating multiple specialized CLI AI agents for complex workflows.

Terax↗

Terax is a lightweight, terminal-first AI-native development workspace that integrates an editor, AI agents, and live web preview, emphasizing reviewable diffs for agent-proposed changes.

Terax offers a comprehensive terminal-native environment with built-in AI agents and persistent memory, directly competing with Herdr's focus on terminal-native agent runtime and persistent workspaces. Both are free and open-source, but Terax adds an integrated editor and voice input.

AiderOn Stork Compare

Aider is a flexible terminal AI coding agent that supports multiple LLM providers and offers robust Git integration with automatic, meaningful commits and diff-aware context management.

Aider is a direct competitor in the terminal-native AI agent space, particularly for coding tasks, offering strong Git integration that Herdr doesn't explicitly highlight. While Herdr focuses on runtime and multiplexing for general agents, Aider specializes in coding workflows and multi-provider LLM support.

Google's Agents CLI / Google ADK↗

Google's Agents CLI, part of the Google ADK, is a specialized tool for building, evaluating, and deploying AI coding agents with built-in session management and deep integration into Google Cloud infrastructure.

This offers a more enterprise-focused alternative to Herdr, providing a CLI for managing the entire lifecycle of AI agents, including deployment to cloud environments. While Herdr is a general terminal-native runtime, Google's solution is tailored for AI coding agents within the Google Cloud ecosystem, offering a comprehensive framework with built-in debugging and evaluation.
