Terminal drama just got herded
Herdr: Agent multiplexer that lives in your terminal
A new app wants to herd your AI helpers, but the comments are already fighting about tmux
TLDR: Herdr is a new tool for managing multiple AI helpers in one terminal, with split screens, status tracking, and sessions that keep running in the background. Commenters immediately split into camps: some mocked it as a fancy remake of older tools, while others joked and questioned whether it solves real-world remote setup problems.
A new tool called Herdr is pitching itself as the all-in-one command center for people juggling multiple AI helpers in one terminal window. In plain English: it lets you split your screen into sections, keep different agents running at once, detach and come back later, and see which ones are busy, stuck, or finished. The pitch is very much "no bloated app, no fancy wrapper, just the real terminal" — and that hardcore vibe instantly set off the crowd.
The biggest reaction? A classic internet showdown: "new thing" versus "we already have this." One commenter fired the opening shot with the brutally short "Just use tmux no?" which is basically the tech world’s version of we have food at home. Another user went the opposite direction and asked the practical question everyone else was probably thinking: can each agent live on a totally different remote machine, or is this all stuck in one place? That uncertainty gave the thread a slightly suspicious, looks cool, but what does it actually do energy.
Then came the taste war. One user said they tried Herdr for days and still thought a rival product, conductor.build, was "way better," dismissing the terminal-only approach as more of a flex than a benefit. Meanwhile, the jokes were strong: "I need a shepherd for my terminals" was the runaway dad-joke of the thread, and another commenter casually dropped their own similar project like a surprise challenger entering the ring. So yes, Herdr launched as a tool — but the real show was the comments turning it into a referendum on whether terminal purists are building the future or just reinventing old nerd furniture.
Key Points
- •Herdr is a terminal-based agent multiplexer that organizes agents into workspaces, tabs, and panes and shows agent states such as blocked, working, done, and idle.
- •The tool supports installation through its own script, PowerShell for Windows preview beta, Homebrew, mise, and downloadable stable binaries for Linux and macOS.
- •Running `herdr` starts or attaches to a background session server, and users can detach without stopping pane processes and later reattach from another terminal.
- •Herdr supports default and named sessions, with separate commands for attaching, listing, and stopping session namespaces.
- •Updating Herdr installs a new binary, while a running server keeps using the old process until restarted or handed off via the experimental `herdr update --handoff` option.
