The name/logo sounds/looks a lot like Rancher (https://www.rancher.com) which is "herding" (docker) containers.
Using their name, logo, and css styles - community project.
Feels wildly misleading.
My setup is ghostty with herdr and this is so much better than using tmux or anything else. The one issue I have with herdr is its default key bindings are not familiar with anything I’ve used before. But it is easy to make Claude configure this - I found you can bind cmd-<key> sequences n addition to ctrl and alt modifiers. The only thing I’m missing is viewing rendered markdown and mermaid charts as part of the agent outputs.
Herdr has been my daily driver for about a month now. It cant auto-name sessions like every other multiplexer though. That one stupid feature is so valuable I'm considering moving on.
This does not seem to be an official product by Herdr themselves.
Use at your own risk.
I actually enjoy herdr a lot, and not just for agent management but the whole multiplexer is plenty powerful defaults and easier than tmux.
At some point though, it's too much information for my tiny human brain to process, even more than 3 agents is hard to manage and context switch. What is the point of managing herd of swarm of whatever I wonder?
