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.
But I’m already using ghostty. I installed herdr but made the mistake of launching it from within tmux and had no idea how to close it.
I then opened it somewhere else, but I had no idea how to interact with it. I also couldn’t get two other windows to “join” the same herdr session, so I gave up and went back to tmux.
For someone who has used screen / tmux for almost 30 years at this point, what does herdr do that tmux can’t?
I use Claude Code extensively. I also use plannotator extensively, which is how I found out about it.
It's all about agentic work. Tmux doesn't know what an Agent is. You use Pi, you use CC, you use Codex, ... they all have primary supports in Herdr with built-in integrations around each of these harnesses
But if you don't do any agentic work, Herdr has 0 value vs. tmux.
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.
Same, but the cost of maintaining a fork fell through the floor in recent years. If a decent fork gains momentum, i can probably even stop spending tokens on mine.
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.
I recently switched to Zellij with Ghostty and the selection/copy/pasting seems to work just fine. I previously used zellij and kitty and I would have issues.
> 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.
Now I’m interested. Does it have basic feature parity? How does it compare to tmux in your experience?
I was able to have a language model configure herdr with the same bindings that I was using in tmux.
It was a very easy transition from one to the other.
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.
herdr is by far the most polished tool in its category. Software geared towards agents is usually vibe coded -- and you can tell. There will be bugs and edge cases and it feels like no thought/care was put into it.
herdr doesn't feel that way to me. The marketing/landing page definitely has LLM-isms, but the application itself is very stable and well thought out.
A true UI is the next logical step and they seem to have done the obvious things. The one surprising bit that nobody seems to be talking about (yet) is the entire UI looks like its controlled via "recipes", so you can customize the UI in ways that you couldn't with traditional software: https://herdr.dev/layouts/
I hope this means an official mobile app is on the horizon!
> herdr is by far the most polished tool in its category.
Can't speak to this, but I like that I didn't feel like I needed to try an alternative. It just did exactly what I needed it to do.
That said - I couldn't find a way to move a pane to a new tab. I can swap panes within a single pane (select -> right click -> swap with focused pane), but I can't find a way to do it between tabs. Maybe it's a skill issue. Anyone have any ideas?
Agreed. I was really sceptical of it and was in the camp of "tmux does all I need" but 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.
Playing with this for a bit, the customization you can do is really cool. You can spin up an agent, tell it to add some functionality, and it all reloads instantly.
For example, I wanted to be able to hide chats from providers when my usage is out for the 5h/weekly period
I'm not sure how they're doing this considering it seems to be written in Rust
That's funny, I got tired of tmux the other day (it got into 100% spin loop from an unsigned int underflow used as a loop condition variable. and I debugged it all by myself like a big boy, without LLMs!) and built something that seems to be identical in architecture in terms of the "supervisor which allocates pty, just stream bytes, client decodes" part. I even use libghostty for the HW accelerated GUI I built. It's the right way to go imo and it's not too difficult to build... hence...
I don't really understand why they would turn this into a company. I become suspicious of products that raise a lot of VC money, implying that they expect a unicorn-ish valuation, where I don't see them being able to justify their valuation via obvious monetization techniques (e.g. selling a classic license for a GUI app where you get updates for some period of time, usually a year, and then you get to keep the software, but no longer get updates, just in case people forgot how things worked before subscriptions).
That usually implies something like selling cloud subscriptions, vendor lock-in, or selling data. I'm happy to be wrong, but it's just an extremely common pattern. And as an aside, I know there's an impulse to monetize everything, but I think we should probably fight that impulse.
Herdr looks awesome, exactly what I need. However, automatic updates worry me in the light of recent supply chain attacks. I don't want be in a situation where one day I just find out I'm running malware on my computer. I'm not sure if there's an option to turn it off.
Didn't have much time to try it this morning, but so far the Herdr app looks fantastic. I am already using herdr on the console to control Claude on my Mac Mini, but having to log in again after closing my Macbook was always annoying. And I missed seeing the code diffs and being able to commit changes in VSCode, which is still my preferred development environment today (with the Claude VSCode extension).
But Herdr app addresses both issues. I don't need to reconnect, and it has a diff tool that allows me to review and commit. Looking forward to work with it!
Does anyone have experience in how herdr compares to Zed?
I'm currently using Zed as my main "agent orchestrator" and IDE because it handles various simultaneous agents quite well, using different harnesses. I'm especially a fan of the diffs for code review and the ability to easily highlight code and add it to context. The way it handles worktrees and git is also nice, IMO.
Having used herdr since its release, the recent 'Emacs is 50' made me decide to go back to it and just vibecode herdr features i use into an emacs package.
It works great so far. I can just ask it to update its layout whenever i think something better is possible. I wont be going back, but the one thing that might change that is a mobile app.
The Herdr website [1] has one of the best demos I have seen, one that I think would blow away those who aren’t nearly as AI-brained as I am. Why are we locked into old, boring UIs when I can just ask the agent for something like cows in a pasture or Windows 98?
News to me, I guess. I have never seen anything like these demos. Most themes in software I use change colors or rearrange existing UI elements rather than create kanban boards and floating interactive cows where they did not exist before.
I mean one where you can say to herdr, make that look like Windows 98. Still can’t think of a good example that’s not already from Windows 98 unfortunately.
I got access around a week ago but found it quite unintuitive and found myself sticking to herdr for now, but was probably a bit quick to judge. What makes tern great for you?
Anyone using this or similar with self-hosted models/engines (not on local machine)? Didn't immediately see anything about that anywhere in the documentation.
Telemetry does not include any data from your terminals, or names of files, folders or projects. In fact they even provide an example JSON payload for you to inspect in the settings dialog.
I was wondering this, too. The desktop appears to be based on herdr-core, and naturally I'd have imagined Herdr Server (terminal) to migrate to herdr-core as well. In fact I'm not even sure why they built herdr-core when they had Herdr Server ..
I also built a similar thing a many. And in my experiments (even though iroh is great) iroh took significantly longer to reconnect vs mosh and ethernal. And actually plain old autossh was the best XP for me to close laptop get on traincopen again on mobile Internet.
So eventually I removed everything other than autossh.
Seeing as how many people are building similar things I'd love to share more. Maybe wanna ad each other respectively to the repo's ?I can share some of my benchmark results
For me connect time is not really a concern, it happens once when I open the app. In my project I'm wrapping agents using ACP and presenting an actual GUI, so latency doesn't really have a perceptible impact. Running Claude Code in a console over any kind of remote connection is gonna feel bad.
Rather than for network performance I'm using iroh because I don't want to need a direct network path to the machines running my agents. Yeah I have Tailscale but that's more work to set up and I don't want my app to depend on users have a TS network.
To elaborate on my usecase that herdr didn't so at all the the beginning but still does not do well: I have many vm's in different clouds working on different projects with different secrets that I want to keep isolated ( now also at home lan machines which when im travel get aliased to their tail scale address)
So my biggest requirements are around making isolation between environments convenient but safe from supply chain attacks .
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.
Your comment is so comically dumb.. Herdr is yet another recently vibe coded ai helper in a niche category. You wouldn't miss anything about frontier ai or coding agents if you don't use herdr and/or terminal multiplexers in your workflow.
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.
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.
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.
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
Glad to see the desktop app and after did some research seems its like rex and with some once feature and it even have a Win98 easter egg if you can find it:)
Currently I am not switch to it because I just have my own app talk to the herdr daemon via my apps builtin tailscale and it works great
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.
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 they need to “allow” this specifically. Every new pane opens in a shell prompt. You must start the agent from there, so you can start each agent with different keys/accounts already.
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.
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.
Fantastic news, I may have to switch back (or combine this with Paseo on my phone). I hope the RAM usage is a lot better as Paseo tends to OOM now and again (the desktop app).
+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.
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.
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 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.
I guess there is some nuance here. Would I pay for a very good agent multiplexer that makes me a lot more productive? Sure, same reason I pay for other apps or services.
But for Herdr specifically? Probably not. There are tons of similar free alternatives and even vibe coding your own is very easy with all the open source code of both herdr and all the alternatives available.
> Would I pay for a very good agent multiplexer that makes me a lot more productive?
That is not the question I am asking.
> But for Herdr specifically? Probably not.
So no then.
That is why they went for VC money since the author knew that donations weren't enough to maintain it in the open.
> There are tons of similar free alternatives and even vibe coding your own is very easy with all the open source code of both herdr and all the alternatives available.
Why would I waste tokens vibe coding something that would go unmaintained in 6 months (because it is "free") over a properly funded project that will last much longer than that?
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.
Herdr is truly awesome. Game changing almost. If you think of all the overly complex agent setups[1] and overly complex software factories[2] to write code... herdr and a pick-your-coding-agent replaces all that with a very simple one thing which just works.
There are many ways to do what herdr does, like tmux, and rex, but in a nutshell:
You launch cli things (claude code, cli tools etc) anywhere inside a herdr process. On your own laptop you magically stay connected to all of them and can monitor, send commands etc. And those processes can talk to each other and control each other too if u want!
For a single person with herdr+tailscale, you can make your own evolving software thingamajig across all the possible computers u have access to (pls don't call it a factory, we didn't call your fingers a factory in the dinosaur days did we).
p.s if someone from cloudflare reads this, would love to have a herdr process in a worker so it appears on my laptop as a thing i can do stuff with. while idle it goes dormant, i send a keystroke and it wakes up, stays awake for a bit.
p.p.s herdr team if u read this can you have a built in so i can instantly launch a vm in one of the many provide a instant vm (or sandbox or whatever the cool kids call it these days). I have been using the railway TS sdk to quickly spin up and throw away sandboxes, but why not just integrate <choose-your-sandbox-provider> in herdr and that is one way to charge money - pay herdr or provide my API key for vm/sandbox provider. Bonus points if it can sleep and charge less. Sort of like fly's sprites but more awesome.
I have multiple projects running in different locations/timezones - so I don't often need to have an agent running on a pc elsewhere - but just being able to smartly use herdr (also using rex) to set up a persistent service on those computers removes all the friction which used to exist with ssh keys and other things.
So I could do all these things before, tools like herdr make it easier, smoother.
Now tmux and ssh keys enabled all this before. So in a sense, nothing new here. but its a bit like dropbox - i used rsync back then, dropbox just made it easier to setup sharing and use without thinking.
My current anecdotal example: if you're building cross-platform native apps, you need to run agents on macOS and Windows, because xcodebuild only runs on macOS and the Windows SDK is only available on Windows.
The tabs mechanism didn't do it for me so I rolled my out (self-plug at [0]).
While it's not "agent-first" thanks to rich MCP I often use direct terminal control from one orchestrator agent to drive another one, and I haven't seen any generic solution like that.
Since I'm moving my work VM yesterday I even started working on ssh persistence using planted cross-compiled PTY host library. If anyone's interested check it out, I expect to roll it out within a week or so.
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.

Same, but the cost of maintaining a fork fell through the floor in recent years. If a decent fork gains momentum, i can probably even stop spending tokens on mine.
It's such a good experience. Try it out, later we fork if they pull anything funny.
It's open source so if that changes you can always fork? I already have some personalizations accruing on my fork.
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.

Herdr is great, one of the exceptionally few TUI applications I actually use daily
On the note of libghostty it does get me very excited about the new multiplexer thing Hashimoto is building with it
This thing, presumably: https://www.superlogical.com/rex/docs/installation
Rex (by Hashimoto/Superlogical) is good. It’s really, really good. Feels and looks great.

Got my invite today. My jaw dropped.
Does herdr have a mobile app like Orca?

Can you use Zed with your regular Claude subscription?
I've been using Orca for this as it's the most popular on GitHub and seems to have more features. Is there anything notable that this offers over it?

It works great so far. I can just ask it to update its layout whenever i think something better is possible. I wont be going back, but the one thing that might change that is a mobile app.
I'd love to give it a spin if you ever publish it.
The Herdr website [1] has one of the best demos I have seen, one that I think would blow away those who aren’t nearly as AI-brained as I am. Why are we locked into old, boring UIs when I can just ask the agent for something like cows in a pasture or Windows 98?
[1] https://herdr.dev
We're not, plenty of applications support custom themes.
I have never used an application where I can type in anything close to "make this look like Windows 98" and it just works.
For all applications that support theming you can ask an agent "make this look like windows 98"
don't quite understand how typing it into a popup instead of an agent makes it revolutionary
News to me, I guess. I have never seen anything like these demos. Most themes in software I use change colors or rearrange existing UI elements rather than create kanban boards and floating interactive cows where they did not exist before.
I mean one where you can say to herdr, make that look like Windows 98. Still can’t think of a good example that’s not already from Windows 98 unfortunately.
In this vein I’ve started using Tern (https://stencil.so/tern), but it’s closed beta, from the creator of Oh My Pi.
This space seems to be heating up, everyone wanting to build the single pane of glass for agentic work.
There's still space for innovation and UIUX improvements so why not I say
Wow, that site is gorgeous
I got access this week and I am blown away at how much better it makes oh-my-pi, and omp was already great!
I got access around a week ago but found it quite unintuitive and found myself sticking to herdr for now, but was probably a bit quick to judge. What makes tern great for you?
I've got access weeks ago, seems I've completely misunderstood what it does!
Anyone using this or similar with self-hosted models/engines (not on local machine)? Didn't immediately see anything about that anywhere in the documentation.
> 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)
Telemetry does not include any data from your terminals, or names of files, folders or projects. In fact they even provide an example JSON payload for you to inspect in the settings dialog.
How does it compare to Rex? (I use Rex but haven’t tried herdr so cant compare yet)
I've been waiting for Rex access! How are you using it, have you installed on different servers?
I have more faith in team behind Rex so not putting the time in for Herdr.
The relevant question: is herdr going to be sunset by herdr-app backed by herdr-core?
To me this is a valid signal.
I was wondering this, too. The desktop appears to be based on herdr-core, and naturally I'd have imagined Herdr Server (terminal) to migrate to herdr-core as well. In fact I'm not even sure why they built herdr-core when they had Herdr Server ..
Anyway, the best comment I could find is that one here where even the main dev doesn't know the direction .. https://github.com/herdrdev/herdr-app/issues/63#issuecomment...
Lack of vision and fragmentation is concerning
I've been building something similar except it uses iroh for P2P instead of SSH. Would really like to use this but I don't want to use SSH.
edit: nevermind I see it presents a console rather than wrapping the agent with a native GUI. This won't work well on high latency connections.
I also built a similar thing a many. And in my experiments (even though iroh is great) iroh took significantly longer to reconnect vs mosh and ethernal. And actually plain old autossh was the best XP for me to close laptop get on traincopen again on mobile Internet.
So eventually I removed everything other than autossh.
Seeing as how many people are building similar things I'd love to share more. Maybe wanna ad each other respectively to the repo's ?I can share some of my benchmark results
For me connect time is not really a concern, it happens once when I open the app. In my project I'm wrapping agents using ACP and presenting an actual GUI, so latency doesn't really have a perceptible impact. Running Claude Code in a console over any kind of remote connection is gonna feel bad.
Rather than for network performance I'm using iroh because I don't want to need a direct network path to the machines running my agents. Yeah I have Tailscale but that's more work to set up and I don't want my app to depend on users have a TS network.
To elaborate on my usecase that herdr didn't so at all the the beginning but still does not do well: I have many vm's in different clouds working on different projects with different secrets that I want to keep isolated ( now also at home lan machines which when im travel get aliased to their tail scale address)
So my biggest requirements are around making isolation between environments convenient but safe from supply chain attacks .
I wonder what usecase you were optimizing for
This sounds cool and a great use case for Iroh
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 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 not exactly obscure. I would argue your effort to follow ai hasn’t been that effective.
Your comment is so comically dumb.. Herdr is yet another recently vibe coded ai helper in a niche category. You wouldn't miss anything about frontier ai or coding agents if you don't use herdr and/or terminal multiplexers in your workflow.
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.
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.
Yes, become too big not to be acquired.
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
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.
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.
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.
I've been using a Collie on Android to connect to my herdr server, it's very good
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.
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.
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
Glad to see the desktop app and after did some research seems its like rex and with some once feature and it even have a Win98 easter egg if you can find it:)
Currently I am not switch to it because I just have my own app talk to the herdr daemon via my apps builtin tailscale and it works great
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.
I think it's just you https://www.ssllabs.com/ssltest/analyze.html?d=herder.dev&la...
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 they need to “allow” this specifically. Every new pane opens in a shell prompt. You must start the agent from there, so you can start each agent with different keys/accounts already.
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.
I hope they release a mobile app too
Me too in the meantime I'm using https://github.com/moezakura/mux-pod but the UI is terrible
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.
Fantastic news, I may have to switch back (or combine this with Paseo on my phone). I hope the RAM usage is a lot better as Paseo tends to OOM now and again (the desktop app).
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
+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.
How does it compare to CMUX?
It works great in Ghostty not sure if I need another standalone app. I’ll definitely try it out but my expectations are low.
There is a Windows 98 mode w/ minesweeper, solitaire, and clippy!
Edit: oh neat! Its self editing.
How does it compare to cmux and wave terminal?
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.
Another desktop application without a screenshot in the Readme.. sigh..
Their website has lots of screenshots
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.
is this similar to zmx?
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.
u can do all this with react and tailwind tho lol.
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?
I guess there is some nuance here. Would I pay for a very good agent multiplexer that makes me a lot more productive? Sure, same reason I pay for other apps or services.
But for Herdr specifically? Probably not. There are tons of similar free alternatives and even vibe coding your own is very easy with all the open source code of both herdr and all the alternatives available.
> Would I pay for a very good agent multiplexer that makes me a lot more productive?
That is not the question I am asking.
> But for Herdr specifically? Probably not.
So no then.
That is why they went for VC money since the author knew that donations weren't enough to maintain it in the open.
> There are tons of similar free alternatives and even vibe coding your own is very easy with all the open source code of both herdr and all the alternatives available.
Why would I waste tokens vibe coding something that would go unmaintained in 6 months (because it is "free") over a properly funded project that will last much longer than that?
The cost of maintenance is never "free".
Are you asking the same question to emacs users?
Yes. So you donated to Emacs as a user?
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.
Rex will as well apparently
herdr has native support for remote machines. Both the CLI and the new app have this.
At work I do much of my work on a ec2 box via ssh with herdr
I love herdr, nice work team!
Herdr is truly awesome. Game changing almost. If you think of all the overly complex agent setups[1] and overly complex software factories[2] to write code... herdr and a pick-your-coding-agent replaces all that with a very simple one thing which just works.
There are many ways to do what herdr does, like tmux, and rex, but in a nutshell:
You launch cli things (claude code, cli tools etc) anywhere inside a herdr process. On your own laptop you magically stay connected to all of them and can monitor, send commands etc. And those processes can talk to each other and control each other too if u want!
For a single person with herdr+tailscale, you can make your own evolving software thingamajig across all the possible computers u have access to (pls don't call it a factory, we didn't call your fingers a factory in the dinosaur days did we).

p.s if someone from cloudflare reads this, would love to have a herdr process in a worker so it appears on my laptop as a thing i can do stuff with. while idle it goes dormant, i send a keystroke and it wakes up, stays awake for a bit.
p.p.s herdr team if u read this can you have a built in so i can instantly launch a vm in one of the many provide a instant vm (or sandbox or whatever the cool kids call it these days). I have been using the railway TS sdk to quickly spin up and throw away sandboxes, but why not just integrate <choose-your-sandbox-provider> in herdr and that is one way to charge money - pay herdr or provide my API key for vm/sandbox provider. Bonus points if it can sleep and charge less. Sort of like fly's sprites but more awesome.
Can you explain more about why you need to distribute agents between computers? Why not just run them on your local computer?
It depends on use cases.
I have multiple projects running in different locations/timezones - so I don't often need to have an agent running on a pc elsewhere - but just being able to smartly use herdr (also using rex) to set up a persistent service on those computers removes all the friction which used to exist with ssh keys and other things.
So I could do all these things before, tools like herdr make it easier, smoother.
Now tmux and ssh keys enabled all this before. So in a sense, nothing new here. but its a bit like dropbox - i used rsync back then, dropbox just made it easier to setup sharing and use without thinking.
My current anecdotal example: if you're building cross-platform native apps, you need to run agents on macOS and Windows, because xcodebuild only runs on macOS and the Windows SDK is only available on Windows.
Because they use resources (tests, etc) and once you have a few running it impacts you.
The tabs mechanism didn't do it for me so I rolled my out (self-plug at [0]).
While it's not "agent-first" thanks to rich MCP I often use direct terminal control from one orchestrator agent to drive another one, and I haven't seen any generic solution like that.
Since I'm moving my work VM yesterday I even started working on ssh persistence using planted cross-compiled PTY host library. If anyone's interested check it out, I expect to roll it out within a week or so.
