Herdr is a terminal-native agent multiplexer — every coding agent at a glance, real terminal views, detach and reattach anywhere without losing sessions.
Herdr is a tmux-style agent multiplexer that lives in the terminal and is designed for the era of AI coding agents. It gives developers a single dashboard where every running agent is visible at a glance — blocked, working, or done — with real terminal views instead of a wrapped or interpreted UI. Sessions detach and reattach from any terminal or over SSH and survive restarts, so agents keep running in the background while the operator moves between machines. Agents themselves can use Herdr via a pure socket API: they can spawn panes, read output, and wait on each other, and there is a documented agent-skill so LLM tools can drive the multiplexer. It ships as a single Rust binary (no Electron) that runs in whatever terminal you already use, with plugins, keyboard and mouse first-class controls, and an AGPL 3.0 license.
Herdr is a terminal-native agent multiplexer designed for developers, allowing users to manage multiple coding agents simultaneously. It provides real terminal views, enabling detachment and reattachment of sessions anywhere without losing progress, enhancing productivity and workflow efficiency.
Herdr's functionality revolves around its ability to manage multiple terminal sessions effectively. It operates as an agent multiplexer, allowing developers to open several coding environments within a single terminal window. This feature is particularly useful for developers who work on multiple projects simultaneously or need to shift between different programming languages and frameworks.
For example, if a developer is working on a Python project but needs to switch to a Node.js task, they can simply detach from their Python session and reattach to the Node.js environment without losing any unsaved work.
Avoid common pitfalls such as not saving work before detaching or mixing unrelated sessions, which can complicate your workflow.
Herdr operates by integrating various functionalities such as real-time visibility of coding agents, detachable sessions for ongoing tasks, and a versatile socket API for seamless orchestration. This powerful tool enhances remote development and simplifies agent management, making it easier to monitor and control multiple coding agents effectively.
Herdr is designed to optimize the management of coding agents like Claude, Codex, or Cursor. It features:
Agent Multiplexer: This allows users to view all active coding agents with real terminal views, providing insights into their status—blocked, working, or completed. Users can easily monitor multiple tasks at once.
Detach and Reattach Anywhere: Herdr's sessions are persistent, meaning you can detach from a session and later reattach from any terminal or via SSH. This feature is crucial for long-running agent jobs, allowing users to check on tasks without interrupting them.
Socket API for Agents: The pure socket API enables agents to communicate efficiently, with capabilities to spawn new panes, read outputs, and synchronize their operations. This promotes effective agent-to-agent orchestration, facilitating complex workflows where one agent can manage sub-agents.
Keyboard + Mouse Interaction: Herdr supports a hybrid interaction model, combining tmux-style prefix keys with intuitive mouse actions like clicking and dragging. This flexibility allows users to choose their preferred method of interaction for any given moment.
Plugin Marketplace: The herdr.dev plugin marketplace provides a platform for extending functionalities. Users can enhance their workflows with various plugins tailored for specific needs, enriching their coding environment.
Herdr offers essential features such as a real-time Agent Multiplexer, seamless session management with detach and reattach capabilities, a flexible Socket API, intuitive keyboard and mouse interactions, and a Plugin Marketplace for enhanced workflows. These functionalities make Herdr a powerful tool for managing coding agents efficiently.
Herdr is designed to optimize the management of coding agents through several key features:
Agent Multiplexer: This feature allows users to view all active coding agents concurrently, providing a clear terminal interface. Users can see the status of each agent—whether it's blocked, actively working, or completed—without the confusion of wrapped or interpreted output. This visibility is crucial for efficient debugging and monitoring.
Detach and Reattach Anywhere: Users can detach their sessions and reattach them from any terminal or via SSH. This ensures that long-running agents continue to operate in the background, making it ideal for developers who need flexibility in their workflow. For instance, if a user needs to switch devices or reconnect to a remote server, their session remains intact, allowing for seamless transitions.
Socket API for Agents: The pure socket API empowers agents to manage their own processes, including spawning new panes and reading outputs as needed. This feature supports a documented agent-skill, enhancing the customization and extensibility of agent behavior, which is perfect for advanced users looking to create tailored workflows.
Keyboard + Mouse First Class: Herdr incorporates tmux-style prefix keys for keyboard navigation, alongside mouse capabilities like clicking, dragging, and splitting panes. This hybrid interaction model allows users to choose their preferred method for managing agents, catering to both keyboard-centric and mouse-centric workflows.
Plugin Marketplace: Users can extend their Herdr experience through the herdr.dev plugin marketplace. This feature enables the addition of custom plugins that can enhance panel functionalities and streamline workflows, making it easy to adapt Herdr to specific needs or preferences.
Herdr is designed for developers and teams who require efficient management of coding agents. It supports features like monitoring a fleet of agents, handling long-running tasks, enabling remote development, orchestrating agents, and streamlining terminal workflows, making it ideal for anyone involved in coding and software development.
Herdr is particularly beneficial for software developers who need to manage various coding agents such as Claude, Codex, and Cursor. With Herdr, users can watch these agents operate across different repositories from a single dashboard, enhancing visibility and control.
Coding Agent Fleet Management: Users can oversee a swarm of agents, making it easy to track their progress and coordinate efforts across multiple projects. For example, if a team is working on different modules of a larger application, Herdr allows seamless oversight of each agent's tasks.
Long-Running Agent Jobs: Developers often initiate tasks that require significant time to complete. Herdr allows users to kick off these multi-hour jobs and detach from their sessions, enabling them to return later without losing any progress. This is particularly useful for tasks like data processing or large-scale code compilation.
Remote Development: With Herdr, developers can SSH into their workstations, reattaching to the exact multiplexer session where agents continue to operate. This feature ensures that work does not halt when switching between devices.
Agent-to-Agent Orchestration: Users can utilize the socket API to allow one agent to spawn sub-agents, enabling a modular approach to task management. This means that complex workflows can be broken down into manageable parts, improving efficiency.
Terminal-Centric Workflows: Herdr replaces the need for complex shell tricks and tmux configurations with a user-friendly multiplexer that understands the lifecycles of agents. This integration simplifies terminal operations, allowing developers to focus on coding rather than managing tools.
Herdr is completely free to use, offering users access to its features without any subscription or payment requirements. This makes it an excellent option for individuals and businesses looking for efficient solutions without financial commitments.
