I tried herdr recently, and I missed many tmux features I really liked.
tmux has a better `prefix-[` mode where you
1) can do visual selection using line/block mode
2) you can use `o` to switch to other side (just like vim)
3) it pauses/freezes the state of the output so you have time to capture
In herdr, its very basic and incomplete if you're a vim/nvim/tmux power user. And if you're in a TUI that shows some text and then hides it, its hard to do the selection in herdr before it disappears.
To give herdr credit, I did like it's `prefix-e` which opens the history in vim so you can you real selection utils.
As I was looking at herdr, I found there many other solutions that were like it built on the more robust tmux. I am still evaluating, but there are plenty of solutions that have hooks to observe what's going on in agents in other panes/windows like herdr.
I like the Primeagen's `tmux sessionizer` style solutions for nvim to work with git worktrees that each agent may be in. And I like the tmux-agent-sidebar.
Same here, I do not see the point of herdr if you're already using tmux. It's very easy to add hooks to your favorite harness to display a notification in tmux when it's done working.
I started using herdr last night, and was able to get a workflow I've wanted to set up for a while working, which is to be able to talk to a managing agent in my car and check on / update claude sessions. It uses Telnyx SIP and LiveKit cloud, and I'm using Qwen3.6 35B-A3B quite successfully as the voice layer router. It's still very early but it works quite well.
If you decide to try it out, please make sure to read the security implications. There is no sandboxing added as of yet, and guardrails are pretty minimal.
