Shows which agents need attention
“I started using this today and am really enjoying the notifications when agents are awaiting input, and the status indicators!”
Comment from 29 Jun 2026 in “Herdr: Agent multiplexer that lives in your terminal” “a fairly polished agentic multiplexer TUI, can easily spawn or destroy windows based on subagent activity”
Comment from 29 Jul 2026 in “Mitchellh starts a new company: Superlogical” “When running many agents something like the "idle/working workstreams" gutter is honestly helpful though.”
Comment from 30 Jul 2026 in “Mitchellh starts a new company: Superlogical” - Comment from 6 Aug 2026 in “Herdr is joining Y Combinator. The runtime stays open”
- Comment from 7 Jul 2026 in “Herdr: One terminal to rule them all”
Great tmux alternative even without AI
“I actually enjoy herdr a lot, and not just for agent management but the whole multiplexer is plenty powerful defaults”
Comment from 11 Sep 2026 in “Herdr Studio” “It worked out of the box, has actually good, working mouse support, quickly ships fixes, and the defaults are sane”
Comment from 7 Jul 2026 in “Herdr: One terminal to rule them all” “To me herdr feels more like a modern alternative to tmux or zellij with the agent features being a nice add on.”

Seamless remote and SSH sessions
“it is honestly fantastic and ever since they added the ability to access multiple ssh machines from one herdr session I just live inside it”
Comment from 30 Oct 2026 in “Herdr has released native app” “the main reason is the remote sessions. I can copy and paste text and files in a remote session with no extra config, it's amazing!”
Comment from 30 Oct 2026 in “Herdr has released native app” “it's been really nice for a specific use case: running agents locally alongside agents in a remote sandbox environment”
Comment from 29 Jun 2026 in “Herdr: Agent multiplexer that lives in your terminal” - Comment from 26 Oct 2026 in “iPhone Duo Teardown”
Handles multiple projects and worktrees
“it shines when you are working with multiple projects, with multiple worktrees, and multiple agents within those projects”
Comment from 30 Oct 2026 in “Herdr has released native app” “lets me have the same project worked on side by side by different models, each in its own git worktree”
Comment from 23 Oct 2026 in “Kimi K3.1 Pro and K3.1 Pro Highspeed” “just having workrees with a single click and a visual tree/children hierarchy was the killer feature”

What people warn about
Each mark is one comment
VC backing raises lock-in fears
“I am wary of VC backed developer tools that seek to innovate in well established open source niches.”
Comment from 6 Aug 2026 in “Herdr is joining Y Combinator. The runtime stays open” “Getting locked into a product that is pressured to achieve VC returns and thus becomes enshittified.”
Comment from 30 Oct 2026 in “Herdr has released native app” Little gain over existing Ghostty setup
“bounced after like a week because ghostty + notifications + harness extensions gave me enough that it wasnt worth learning the new thing”
Comment from 30 Oct 2026 in “Herdr has released native app” “I don't see much benefit over herdr in Terminal/Ghostty, and I need to reconfigure my agents to make it work too.”
Comment from 30 Oct 2026 in “Herdr has released native app” Confusing to learn and set up
“I had no idea how to interact with it. I also couldn't get two other windows to "join" the same herdr session”
Comment from 30 Oct 2026 in “Herdr has released native app” “the fork from the original herdr tui (without any explanation of the plan or reasons) is quite confusing”

What people said
40 of the 370 comments that mention it, newest first. Each links to the original comment.
“Each space is persistent contains persistent terminals like tmux, so disconnections do not affect them.”
“herdr has defined a few core primitives (machine -> space -> tab -> pane -> terminal) and lets you customize all the ui around it.”
“the fork from the original herdr tui (without any explanation of the plan or reasons) is quite confusing”
“Looks good but doesn't have a browser yes, like all the desktop applications of major harnesses have.”
“bounced after like a week because ghostty + notifications + harness extensions gave me enough that it wasnt worth learning the new thing”
“Getting locked into a product that is pressured to achieve VC returns and thus becomes enshittified.”
“it shines when you are working with multiple projects, with multiple worktrees, and multiple agents within those projects”
“i imagine one reason herdr might be better would be that you're not stuck in the anthropic ecosystem”
“the main reason is the remote sessions. I can copy and paste text and files in a remote session with no extra config, it's amazing!”
“it will allow you switch quickly between those 10 terminals without spending too much time on locating those”
“everything that can be done in Herdr is trivially discoverable by asking a CC (or equivalent) session inside Herdr”
“the vibed copy is for me offputting and a sign even the author might not understand what he made”
“I don't see much benefit over herdr in Terminal/Ghostty, and I need to reconfigure my agents to make it work too.”
“I had no idea how to interact with it. I also couldn't get two other windows to "join" the same herdr session”
“it is honestly fantastic and ever since they added the ability to access multiple ssh machines from one herdr session I just live inside it”
“herdr and a pick-your-coding-agent replaces all that with a very simple one thing which just works.”
“Herdr is designed for AI usage, but I actually really like it even for just normal terminal multiplexing.”
“The built-in terminal app also works nicely with herdr and Tailscale to let me connect to my work machine.”
“lets me have the same project worked on side by side by different models, each in its own git worktree”
“So instead of remembering how to split a pane, you just right click with the mouse and choose "split" from the popup menu”
“It can automatically restart an agent cli while resuming the session they were running before the reboot.”
“sometimes you just need to stop everything and restart all the agents. Losing progress notification state in the process”
“I actually enjoy herdr a lot, and not just for agent management but the whole multiplexer is plenty powerful defaults”
“herdr is abstracted up a level from the agent, so you actually get more benefit by using Codex with herdr”
“The reason Herdr is novel, IMO, is its runtime owns the PTYs and builds a bidirectional messaging system on top of that.”
“just having workrees with a single click and a visual tree/children hierarchy was the killer feature”
“I am wary of VC backed developer tools that seek to innovate in well established open source niches.”
“It's a great bit of software, the UI is focused on switching between multiple agents quickly.”
“the main advantage of herdr is that when I have the codex integration activated, herdr will keep track of the codex session ids”
“To me herdr feels more like a modern alternative to tmux or zellij with the agent features being a nice add on.”
“When running many agents something like the "idle/working workstreams" gutter is honestly helpful though.”
“a fairly polished agentic multiplexer TUI, can easily spawn or destroy windows based on subagent activity”
“Quite handy to apply since you can instruct models to run devservers in herdr panes or workspaces”
“With the herdr skill you can have subagents be managed via tabs or panes, which gives them more visibility”
“deferring the window management to the OS sounds great in theory, but in practice it falls short”
“the best in terms of visibility of what my agents are doing and which of them need attention”
“It worked out of the box, has actually good, working mouse support, quickly ships fixes, and the defaults are sane”
“I started using this today and am really enjoying the notifications when agents are awaiting input, and the status indicators!”
“it's been really nice for a specific use case: running agents locally alongside agents in a remote sandbox environment”
“Being able to launch from a terminal means this one can (hopefully) run from inside the sandboxing setup I use for coding agents.”
