What it is

herdr is described as a runtime that runs coding agents inside a background server, managing terminal panes and sessions. It provides a CLI and socket API for agent-driven pane orchestration, supports tmux-style interactions (prefix keys, click, drag, split), and emphasizes running existing tools (e.g., Claude, Codex) without wrapping them.

How it works

The project exposes a Rust-based binary that acts as the runtime. It spawns panes, coordinates agent prompts, and tracks pane states (working, blocked, idle). It operates as a background server to which terminals attach and detach. It supports plugins and integrations to extend workflows and panes.

Getting started

Install:

curl -fsSL https://herdr.dev/install.sh | sh

or brew install herdr · mise use -g herdr · windows beta: powershell -ExecutionPolicy Bypass -c "irm https://herdr.dev/install.ps1 | iex" · binaries

then start it:

herdr

You can detach/reattach with ctrl+b q to detach and herdr to reattach.
