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.

Now I’m interested. Does it have basic feature parity? How does it compare to tmux in your experience?
I started using it last week, the tui interface is very polished and it is mouse-friendly. It also allows you to configure the notification channels. Its a different beast from tmox, I'd say its quite more user-friendly and gives you a list of your running agents and their status directly on the interface.
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.
Pretty much the first thing I tried to set up with I heard about Zellij and decided to give it a shot a while back was how to scroll back and copy paste text without using the mouse, since that's one of the core features of tmux for me. If my recollection is correct, the closest thing that I was able to figure out was some sort of built-in way to open output in a vim buffer, with the info I found when googling basically saying that it was intentionally not something the developers felt like it was important to implement anything closer to tmux for. Maybe it's changed since then but I distinctly got the impression that it using it would force me to adapt to a bunch of new workflows that didn't resemble anything I had seen before, and it didn't really seem worth the effort.
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.
It works now. Haven't restarted browser/mac - so not sure what went wrong.
Anyways, Herdr looks powerful - will try it soon. One thing I find missing in every single one today, is that they do not allow using a different AI account based on the workspace/project you are on. It would come in handy in case of shared family machine.
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.
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.
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.
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.
Your comment is so comically dumb.. Herdr is yet another recently vibe coded ai tool. You wouldn't miss anything about frontier ai if you don't use herdr and/or terminal multiplexers for cli coding agents.
herdr is moderately well known if you look into agent multiplexers. IMO it is the best one from what I have tried (Paseo and Conductor are competitors in this area)
It's not a harness -- it's really more like a tmux for agents.
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.
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.
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.
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.
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.
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.
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
I really enjoyed herdr at first but ever since they get VC funding I am avoiding it. Enshittification due to monetization pressure is gonna be incoming.

Tui-in-guis like orca are nice mostly because of sensible keybinds without prefix or leader
Probably a good idea if you work with sensitive data (and you’re already on Zero Data Retention)
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.
So I wouldn’t blame the commenter above.

At work I do much of my work on a ec2 box via ssh with herdr
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.
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
