Herdr: Why Developers Are Replacing Tmux with AI Agents

Herdr is a terminal multiplexer built specifically for running AI coding agents like Claude Code, Codex, and Pi side by side. In this video I walk you through installing Herdr, touring the UI, and setting it up to manage multiple coding agents at once. If you already use tmux, the defaults will feel familiar, but Herdr adds agent-aware status tracking, built-in git worktree management, and a thin client that works over SSH. --- What you'll learn: - How to install Herdr and set up agent integrations for Claude Code, Codex, and Pi - How to use Herdr's built-in git worktree support to run agents in parallel - How to organize multiple projects with workspaces, tabs, and splits - How the plugin marketplace and Herdr Automations (cron for agents) work - How to connect to a remote machine over SSH and paste images into a remote agent session --- Resources mentioned: - Herdr: https://herdr.dev/?utm_source=youtube&utm_medium=description&utm_campaign=herdr-tmux-ai-agents - Herdr docs: https://herdr.dev/docs/?utm_source=youtube&utm_medium=description&utm_campaign=herdr-tmux-ai-agents - Herdr plugin marketplace: https://herdr.dev/plugins/?utm_source=youtube&utm_medium=description&utm_campaign=herdr-tmux-ai-agents Get the files + my full collection of Claude workflows: → https://www.damiangalarza.com/newsletter?utm_source=youtube&utm_medium=description&utm_campaign=herdr-tmux-ai-agents --- Timestamps: 0:00 What is Herdr? 0:16 Installing Herdr 0:50 UI tour: spaces, terminal, agents 1:06 Leader key and keybindings 2:26 Settings, themes, and notifications 3:09 Setting up agent integrations (Claude Code, Codex, Pi) 4:00 Installing the Herdr agent skill 4:31 Built-in git worktrees 5:33 Managing worktrees with an agent 8:02 Multiple workspaces across projects 9:16 Tabs and splits inside a workspace 9:41 Spawning a dev server from an agent 10:15 The plugin marketplace 10:41 Herdr Automations (cron for agents) 11:16 Session persistence (detach/reattach) 11:44 Remote access over SSH 12:08 Pasting images into a remote session --- About me: I'm Damian Galarza, a fractional CTO and AI engineering consultant with 15+ years building production software. I help engineers and teams ship real AI systems, and I make practical tutorials on building with AI, not just using tools like Claude Code.
