Herdr
What is Herdr?
Herdr is an open-source runtime for running coding agents in persistent terminal sessions. Its background server keeps panes, shells, agent processes, and project workspaces available when a terminal client detaches. Developers can run multiple agents across projects and reconnect locally or through SSH from another machine. Herdr detects supported agents, displays their working, idle, or blocked states, and provides integrations for session restoration. Its Apache-2.0-licensed runtime is free to use on macOS, Linux, and Windows.
How to use Herdr?
- Install Herdr on macOS, Linux, or Windows using its official installer or a supported package manager.
- Open a terminal in your project directory and run herdr to start or attach to a persistent session.
- Launch a coding agent in a pane, then detach and reconnect later with herdr or through SSH.
Herdr's Core Features
Persistent terminal sessions: Keep panes, shells, agents, and running processes alive when the client detaches.
Local and remote access: Reconnect to sessions on your machine or attach to remote hosts through SSH.
Agent state tracking: See supported agents' idle, working, or blocked status and find sessions that need attention.
Workspace and pane organization: Arrange agents and project terminals across workspaces, tabs, and panes.
Agent integrations: Install integrations that enable supported agents to restore sessions after a server restart.
Session restoration: Reopen saved session layouts and restore compatible agent sessions after a restart.
CLI automation: Control sessions, panes, agents, and other runtime features from scripts or tools.
Local socket API: Let scripts and agents inspect or control a running Herdr session through its socket interface.
Cross-platform installation: Install stable builds on macOS, Linux, and Windows.
