I switched to herdr this year after a decade of using tmux, and I haven't looked back since. Herdr is wonderful, not only because of the coding agent integrations, but also because it uses libghostty under the hood. So no terminal-emulator-inside-another-terminal-emulator shenanigans.
If you prefer GUIs, I can recommend herdr-gpui which connects to a herdr daemon. It has a bunch of goodies like remote phone pairing, and a built-in browser integration to send screenshots and notes to coding agents.
I've been using Zellij a long time and considered using Herdr, but the VC funding aspect scares me. I don't want to invest a bunch of time in a tool that's going to treat me as a product.
I used Zellij in the past, it is also fantastic and intuitive product. I had issues with... I think selection and copying and pasting which made me abandon it as I was getting frustrated. Herdr has been wonderful and I've been using it for a while.

Now I’m interested. Does it have basic feature parity? How does it compare to tmux in your experience?
Supports SSH to remote machines out of the box, cool. I wonder if the protocol is more efficient than the TUI over SSH, would be nice on crappy connections when traveling.
It is, but if you send more efficient deltas, batch packets more intelligently, and introduce non-blocking UI tricks, the experience can be improved by quite a bit. mosh demonstrates some of that.
If you like the idea of herdr, but want something that isn't opinionated on terminal vs. desktop app and has mobile support, you might like https://github.com/codealong/codealong
Is anyone else finding that it doesn't pick up Claude Code agents? My Agents pane stays empty no matter how many instances I start and work in. Appears to continue to work fine in herdr, though.
+1 I tried quite hard to make things work with tmux, zellij, and even some light custom stuff, but if you have multiple agents running on multiple boxes herdr just works unreasonably well. I really didn't want to like what seemed like a random mix of features, but they've stabilized it to a sensible capability set.
Nice! I have been using herdr for a few months, love it and for me it is a step up from years using tmux. The new native Herdr app is yet another step up. I use multiple Macs with Tailscale connections and the Herdr app makes jumping around to different projects and different machines easier.
Haven't used Herdr before - was looking at README and was looking to check screenshots and documentation. However, Chrome reports the SSL cert to the site https://herdr.dev as invalid. Will wait till it gets resolved.
Darn, title had me thinking they released a mobile app to compliment the TUI daemon.
termux+mosh is fine, but especially on a phone I'd love a slightly more intuitive (or really, efficient) UI. Especially as mosh breaks touch/mouse input on the remote host.
I've never understood the point of the desktop GUI harnesses to run TUI (or at the very least, primarily text-based) programs anyway, but perhaps they're better for onboarding less tech-savvy users.
Moshi is pretty fantastic. I’ve been using it for several months and it works great. The developer is also launching fixes and improvements every week. It’s gotten materially better over the time I’ve been using it and it started out pretty great.
If you like Herdr, you might also appreciate https://github.com/BrokkAi/mjolnir/, which is similar in its multiplexing features (although built on ACP) but offers cross-provider subagents, memory and session log sync, live migration of sessions across profiles and providers, and load balancing across multiple subscriptions.
I have been using herdr for a few months. Then i bought a new machine, installed claude code and asked it to setup herdr. Shockingly claude said it has no idea what herdr was. This was weird.
herdr is great, and the original runs-in-a-terminal vision was cool, but at least on OSX it has a ton of selection management bugs that are pretty sucky.
I really enjoyed herdr at first but ever since they got VC funding I am avoiding it. Enshittification and cloud features due to vc/monetization pressure incoming.
feels like they're trying to get ahead of superlogical's rex.
took all of installing it on windows and setting up my mac as an SSH machine to see the slop all through the UI. i'll just wait for rex's windows client i guess.
I don't think I need it, but Herdr has been absolutely rock solid for me. And I have this app Pairfob that I can check things up on the phone if I really want to. And while I don't use it quite as often, seems to be more solid then Chatgpt (Codex) and other apps.
I have 2 machines and laptop linked together and running things have never been easier.
Which of these various new multiplexers (herdr, cmux, etc) work over ssh, and which have protocols underneath?
I've been scripting tmux for a while now, and it's not the greatest. And when I have a bunch of opencode sessions rolling along often my tmux could usage is smoking. I'd be happy to try other things. But I'd way rather get into something with protocols, that is open to play.

I could not work without it anymore, such an easy solution for a common problem. Will definitely try out the app as well.
I've been using Zellij a long time and considered using Herdr, but the VC funding aspect scares me. I don't want to invest a bunch of time in a tool that's going to treat me as a product.
It's open source so if that changes you can always fork? I already have some personalizations accruing on my fork.

I hope they release a mobile app too

the poor experience on a crappy network connection is an SSH problem unfortunately
It is, but if you send more efficient deltas, batch packets more intelligently, and introduce non-blocking UI tricks, the experience can be improved by quite a bit. mosh demonstrates some of that.

while they do this, i hope they do not drop support for regular/other terminals
ignoring ALL the AI/agent features, herdr has been a decent replacement for tmux with saner defaults
so much so that i'm reaching for installing herdr instead of tmux and i would like to not be locked to a "desktop app" for it

Have you tried moshi? It’s Herdr aware.
Tui-in-guis like orca are nice mostly because of sensible keybinds without prefix or leader
Moshi is pretty fantastic. I’ve been using it for several months and it works great. The developer is also launching fixes and improvements every week. It’s gotten materially better over the time I’ve been using it and it started out pretty great.
try cosyra mobile. Its the best mobile client for herdr. It uses websocket and is has a really smooth ux.

What’s the planned monetization model for all the terminal multiplexers backed by VC funding like Herdr, Rex, etc?
Being acquired for $10B by $1T companies.
If the terminal is just a screen to a remote, they will sell you the remote, completely integrated into the harness.
I think they are all planning to make money on selling cloud or inference
This is the first time I have even hear of Herdr, and I try to make an effort to follow ai.
It's getting very difficult to keep up with all the agent harnesses coming out. I love ai but wow its hard to keep up.
Herdr is not exactly obscure. I would argue your effort to follow ai hasn’t been that effective.
I have been using herdr for a few months. Then i bought a new machine, installed claude code and asked it to setup herdr. Shockingly claude said it has no idea what herdr was. This was weird.
So I wouldn’t blame the commenter above.
A native app is definitely a good thing.
herdr is great, and the original runs-in-a-terminal vision was cool, but at least on OSX it has a ton of selection management bugs that are pretty sucky.
> Usage telemetry is on by default in releases. Turn it off in Settings → Privacy.
Probably a good idea if you work with sensitive data (and you’re already on Zero Data Retention)
There is a Windows 98 mode w/ minesweeper, solitaire, and clippy!
Edit: oh neat! Its self editing.
How does it compare to CMUX?
I really enjoyed herdr at first but ever since they got VC funding I am avoiding it. Enshittification and cloud features due to vc/monetization pressure incoming.
Since you used herdr before it got funding, were you going to donate or pay for it without VC funding?
Yep it’s awesome. I’m going to integrate the core engine to my mobile app so I can control it remotely.
Collie already does pretty well. https://github.com/AltanS/collie
Just termius + tmux works for me on my Android phone and iPad. I have a ntfy topic to alert from Pi when it needs something.
I've been holding this at arms length. Interested, but I'm so stuck on tmux.
feels like they're trying to get ahead of superlogical's rex.
took all of installing it on windows and setting up my mac as an SSH machine to see the slop all through the UI. i'll just wait for rex's windows client i guess.

I love herdr, nice work team!
