This Tmux "Rewrite" Is Actually Brilliant

TL;DR

• DevOps Toolbox (Omer, a self-professed tmux power user with published tmux plugins) reviews Herder (herdr.dev) — the Rust "tmux rewrite" agent-native terminal multiplexer — and, despite arriving maximally skeptical of "multiplexers for agents," mostly converts.
• What won him over isn't the agent features but the package: beautiful defaults (vs "terrible tmux default setups"), a self-explanatory hint bar and keybind popup, mouse-first everywhere, marking-copies-to-clipboard, an 11MB binary that installs via curl in under a second, and a full CLI wrapping a JSON API for scripting.
• The genuinely novel ideas: workspaces as an organizational layer between tmux sessions and windows ("sessions in tmux never felt like first-class citizens"); an agents panel that auto-detects running agents (Pi, OpenCode) with status colors and notification sounds; --remote attach that reads your SSH config; and live handoff — migrate a running session to an updated or remote server keeping layout and history ("tmux-resurrect on steroids").
• Rough edges: agent renaming is CLI-only with opaque IDs and JSON output, no floating panes, no last-tab jump; and he's unmoved by mobile use ("I'm not one to believe anyone actually codes through their phone") and by 50-agent-swarm LinkedIn slop.
• Verdict: keeps tmux locally, adopts Herder as the daily driver on his home-lab box where the agents actually run — the second independent Herder endorsement in the archive after DHH made it the center of his 16-thread setup.

Key moments

• [00:01] The skeptic's opening — "too many projects claiming to be the tmux killers or the multiplexer for agents"; AI-slop-on-GitHub jab lands in the first 20 seconds (frame_0001.jpg).
• [01:21] What Herder is — agent runtime in your terminal; comparison table vs tmux, Zellij, and "worktree orchestrators"; persistent sessions, remote SSH attach, agent state, direct attach.
• [03:16] The creator — Can Çelik, Turkish developer, full-time on Herder, also contributes Pi extensions (LinkedIn profile shown, frame_0015.jpg: "founder, herdr.dev — terminal native runtime for AI coding agents").
• [03:45] Install — one curl, 11MB binary, sub-second install; first-run settings pane, sidebar + empty workspace (frame_0033.jpg shows the herdr status bar).
• [05:03] The sleeper feature — the self-explanatory bottom bar: "I always wanted to build this for tmux and never got around to it... my god, it's good."
• [05:58] Sponsor — Arcade, an actions runtime for agent authorization (frame_0031.jpg).
• [07:03] Workspaces explained — an in-between layer "letting you containerize a bunch of windows and splits without detaching"; "I used tmux for probably 4 years before hearing about sessions."
• [08:20] Agents panel — running Pi auto-registers as an idle entry; task progress reflects live; done = color coding + notification + configurable sounds ([09:11]).
• [11:49] Remote & mobile — herder --remote box reads SSH config and attaches ("that's brilliant"); works via Termius on iOS (frame_0045.jpg) but "this is tiny... I don't see the huge appeal."
• [14:52] Live handoff — transfer a running session to a new/updated/remote server keeping layout and terminal history; only works with Herder's own updater, not Homebrew/mise.
• [15:51] The billion-dollar question — verdict: tmux stays local, Herder becomes the home-lab daily driver where the agents live ([16:17]).

Hook pattern: skeptic's-conversion setup. No cold-open montage — he opens with values ("I'm a big believer in simplicity... sleek, fast, and yes, fun") and immediately establishes hostile priors: AI slop on GitHub, "too many projects claiming to be the tmux killers," and his on-record dismissal of a previous agent multiplexer ("just not worth the hassle"). The hook is the implicit promise that something overcame this skepticism — "slowly... I started thinking, hey, these splits are actually nicer than what I currently have" [00:39]. Credibility-through-reluctance: the review's persuasive power is pre-loaded in the first 60 seconds by how hard he was to win.

Concepts surfaced

• agent-native-multiplexer: the emerging tool category — a terminal multiplexer whose first-class objects are running AI agents (status panel, done-notifications, direct attach), not just panes.
• beautiful-defaults: the actual moat — self-explanatory UI, discoverable keybinds, mouse-everywhere; wins converts where feature checklists don't ("it has the user experience in mind").
• workspace-layer: an organizational tier between sessions and windows that "containerizes" tabs/splits without attach/detach ceremony — fixing tmux sessions' second-class ergonomics.
• live-handoff: migrating a running terminal session (layout + history) to an updated binary or remote server — persistence as a first-class operation.
• cli-wrapping-api: every UI action available as a scriptable CLI call returning JSON — the tmux heritage worth keeping.
• slop-content: (recurring theme) his framing device — GitHub AI-slop projects and "swarm of 50 agents" LinkedIn posts as the noise Herder had to overcome.

[00:02] I'm a big believer in simplicity, especially when it comes to software,
[00:04] especially when it comes to software, and even more so when it comes to my
[00:06] and even more so when it comes to my workflow. Simplicity doesn't mean raw
[00:08] workflow. Simplicity doesn't mean raw dogging. It means sleek, fast, and yes,
[00:10] dogging. It means sleek, fast, and yes, fun. In world where the ease of
[00:12] fun. In world where the ease of producing AI slop and posting it on
[00:14] producing AI slop and posting it on GitHub, yes, it's not even pushing
[00:16] GitHub, yes, it's not even pushing anymore, it's pretty much like posting
[00:18] anymore, it's pretty much like posting on LinkedIn at this point, there's just
[00:20] on LinkedIn at this point, there's just too many projects claiming to be the
[00:22] too many projects claiming to be the team mux killers or the multiplexer for
[00:24] team mux killers or the multiplexer for agents. I've tried tmux, which seems to
[00:26] agents. I've tried tmux, which seems to be extremely popular these days. I
[00:28] be extremely popular these days. I covered it in a video, but the gist of

[00:31] it is just not worth the hassle, at least in my opinion. And this was
[00:33] least in my opinion. And this was exactly my thought trying Herd out. I
[00:35] exactly my thought trying Herd out. I mean, sure, another two way with
[00:37] mean, sure, another two way with notifications, oh wow. But slowly, while
[00:39] notifications, oh wow. But slowly, while playing around and then working with it,
[00:41] playing around and then working with it, I started thinking, "Hey, these splits
[00:43] I started thinking, "Hey, these splits are actually nicer than what I currently
[00:45] are actually nicer than what I currently have in tmux." And then the mouse
[00:47] have in tmux." And then the mouse control and the side panel and
[00:48] control and the side panel and notification, it just kept telling me,
[00:50] notification, it just kept telling me, "Hey, I'm a tmux rewriting rust that's a

[04:20] Configuring everything from alerts through with themes, and more. And there
[04:22] through with themes, and more. And there we have it, a pane on the side that
[04:24] we have it, a pane on the side that doesn't have much yet and an empty
[04:27] doesn't have much yet and an empty workspace. One must give it to Herder,
[04:29] workspace. One must give it to Herder, it has beautiful defaults unlike the
[04:31] it has beautiful defaults unlike the terrible tmux default setups and it is
[04:33] terrible tmux default setups and it is very focused on being self-explanatory
[04:36] very focused on being self-explanatory with guiding through keystrokes and
[04:38] with guiding through keystrokes and options from the bottom. The default
[04:40] options from the bottom. The default control B works both for tmux and Herder
[04:43] control B works both for tmux and Herder and another nice surprise is the
[04:44] and another nice surprise is the question mark pane with keybinds listed
[04:47] question mark pane with keybinds listed and available when you need it. Ever
[04:49] and available when you need it. Ever since finding out about Zellij a couple
[04:50] since finding out about Zellij a couple of years back, I found myself wanting to
[04:52] of years back, I found myself wanting to make tmux a bit more like Zellij. I
[04:55] make tmux a bit more like Zellij. I mean, I wanted to keep my setup but
[04:56] mean, I wanted to keep my setup but adding missing features. Some of these
[04:58] adding missing features. Some of these I've added as plugins that I have on my
[05:00] I've added as plugins that I have on my GitHub and maintain like session
[05:02] GitHub and maintain like session management and floating panes. But one
[05:04] management and floating panes. But one that I always wanted to build and never
[05:06] that I always wanted to build and never got around to is a self-explanatory bar.
[05:08] got around to is a self-explanatory bar. And while I don't think Herder dev even
[05:11] And while I don't think Herder dev even lists this as one of its selling points,
[05:13] lists this as one of its selling points, my god, it's good. You almost always get
[05:16] my god, it's good. You almost always get a hint on where to go next, what
[05:18] a hint on where to go next, what keystrokes or combos to use to create a
[05:19] keystrokes or combos to use to create a new workspace, tabs, splits. There's
[05:21] new workspace, tabs, splits. There's even a pop-up with all the binds should
[05:23] even a pop-up with all the binds should you feel lost. And on top of all these,
[05:26] you feel lost. And on top of all these, the mouse [music] just works everywhere.
[05:28] the mouse [music] just works everywhere. Whether you're renaming a tab, switching
[05:30] Whether you're renaming a tab, switching a split, or attaching to another
[05:32] a split, or attaching to another workspace. And this is exactly how it
[05:34] workspace. And this is exactly how it starts. Herder suggests we create a
[05:36] starts. Herder suggests we create a workspace using our prefix which is
[05:38] workspace using our prefix which is still control B and shift N. And there
[05:41] still control B and shift N. And there we have it, my familiar shell in a very
[05:43] we have it, my familiar shell in a very familiar setting on top that resembles
[05:45] familiar setting on top that resembles the famous catpuccin plugin for tmux as
[05:48] the famous catpuccin plugin for tmux as you can see from my Tmux line on top,
[05:50] you can see from my Tmux line on top, which by the way is my setting and seems

[07:28] session in Tmux, it's not exactly that. It's just another layer you never knew
[07:30] It's just another layer you never knew before. There's tabs and splits as any

[07:34] other Tmux or Zellij user knows, and there are sessions, none of which are

[07:48] sessions. You very much can, but this is unnecessary. And while some would claim
[07:50] unnecessary. And while some would claim it's redundant, I don't know what it is
[07:52] it's redundant, I don't know what it is about it. It just feels more right.
[07:54] about it. It just feels more right. Sessions in tmux always felt like
[07:56] Sessions in tmux always felt like they're not first-class citizens. Some
[07:58] they're not first-class citizens. Some users either don't use them regularly
[08:00] users either don't use them regularly because the tooling is just bad. Some
[08:02] because the tooling is just bad. Some are just unaware. I used tmux for

[08:06] probably 4 years before hearing about sessions in the first place. Okay, back
[08:09] sessions in the first place. Okay, back to Herder. When you hit prefix c, Herder
[08:11] to Herder. When you hit prefix c, Herder will create a new tab. But, what do you
[08:13] will create a new tab. But, what do you know? Such a small yet genius option, a
[08:16] know? Such a small yet genius option, a name pop up. Set the name and let it
[08:18] name pop up. Set the name and let it run. And now, it's time to put the lower
[08:20] run. And now, it's time to put the lower part of the sidebar to use because
[08:22] part of the sidebar to use because that's what most of us are here for
[08:24] that's what most of us are here for after all, running an agent.
[08:26] after all, running an agent. Immediately, it creates an entry under
[08:27] Immediately, it creates an entry under the agent section telling me there's an
[08:29] the agent section telling me there's an idle pie used on some tab. I tried Codex
[08:32] idle pie used on some tab. I tried Codex as well for fun, but I guess Mr. Altman
[08:35] as well for fun, but I guess Mr. Altman and Tim Cook have some stuff to figure
[08:36] and Tim Cook have some stuff to figure out. In the meantime, I wanted to rename
[08:39] out. In the meantime, I wanted to rename my workspace. [music]
[08:40] my workspace. [music] I couldn't find it and thought what the
[08:42] I couldn't find it and thought what the hell? It's a mouse-first terminal, isn't
[08:44] hell? It's a mouse-first terminal, isn't it? Well, right click on it and what do
[08:46] it? Well, right click on it and what do you know? Workspace is now renamed. Your
[08:48] you know? Workspace is now renamed. Your mouse works for everything else.
[08:50] mouse works for everything else. Switching tabs, adding them, and
[08:51] Switching tabs, adding them, and changing stuff around. In tmux, while
[08:54] changing stuff around. In tmux, while motions are already muscle memory for
[08:56] motions are already muscle memory for me, none of this is available. And I get
[08:58] me, none of this is available. And I get why newbies want an easier starting
[09:00] why newbies want an easier starting point. Herder may very well be it.
[09:03] point. Herder may very well be it. Prefix n and p for next and previous
[09:05] Prefix n and p for next and previous will switch tabs back and forth. Let's
[09:07] will switch tabs back and forth. Let's make my local tmux go away to get the
[09:09] make my local tmux go away to get the complete immersive feel of Herder as our
[09:12] complete immersive feel of Herder as our main UI. When you give the AI a task,
[09:14] main UI. When you give the AI a task, the agents [music] pane knows on its own
[09:16] the agents [music] pane knows on its own how to reflect the working progress. And
[09:18] how to reflect the working progress. And a new pie will add itself to the same
[09:20] a new pie will add itself to the same list, allowing for easy control of,
[09:22] list, allowing for easy control of, well, the herd. When a task is done, you
[09:24] well, the herd. When a task is done, you get both a color coding on the agents
[09:26] get both a color coding on the agents panel as well as a UI notification on
[09:29] panel as well as a UI notification on the bottom. Both are configurable,
[09:31] the bottom. Both are configurable, including sounds that I can hear in my
[09:32] including sounds that I can hear in my headphones now that beep when an agent
[09:35] headphones now that beep when an agent is ready or waiting. Marking text
[09:37] is ready or waiting. Marking text immediately gets copied to the
[09:38] immediately gets copied to the clipboard. That's a default behavior
[09:40] clipboard. That's a default behavior that also makes a lot of sense. Even
[09:42] that also makes a lot of sense. Even splits look better on the default Herder
[09:44] splits look better on the default Herder than they are compared to Tmux, which is
[09:46] than they are compared to Tmux, which is another plus for Zellij, I guess. Prefix
[09:49] another plus for Zellij, I guess. Prefix and arrows or V motions will easily get
[09:51] and arrows or V motions will easily get you around them, changing the focus
[09:53] you around them, changing the focus while highlighting the border. Just like
[09:55] while highlighting the border. Just like Tmux, Zellij will zoom in or back out of
[09:58] Tmux, Zellij will zoom in or back out of it again. Prefix Q is comparable to Tmux
[10:00] it again. Prefix Q is comparable to Tmux detach, setting you back in your
[10:02] detach, setting you back in your terminal session, where Herder again
[10:04] terminal session, where Herder again attaches you back in side with
[10:06] attaches you back in side with persistency as expected. Here's Neofetch
[10:08] persistency as expected. Here's Neofetch [music] and Htop because we're fancy and
[10:10] [music] and Htop because we're fancy and a little pie on the side. Both look
[10:12] a little pie on the side. Both look great for experienced users, but also
[10:14] great for experienced users, but also very accessible to newbies with the
[10:16] very accessible to newbies with the mouse everywhere. You'll also notice a
[10:18] mouse everywhere. You'll also notice a small configurable label for agent panes
[10:21] small configurable label for agent panes that help with orientation. I mentioned
[10:23] that help with orientation. I mentioned earlier that Herder is also a CLI
[10:25] earlier that Herder is also a CLI wrapping an API you can use in many
[10:27] wrapping an API you can use in many ways. One of which is listing the
[10:30] ways. One of which is listing the sessions, the current one running,
[10:31] sessions, the current one running, listing the working directory, and the
[10:33] listing the working directory, and the socket path. There's [music] no session
[10:34] socket path. There's [music] no session new command, and if you do search the
[10:36] new command, and if you do search the docs, you'll find a reasonable
[10:37] docs, you'll find a reasonable explanation saying workspaces are pretty
[10:40] explanation saying workspaces are pretty much all you need. When you need better
[10:42] much all you need. When you need better isolation, go right ahead, but I cannot
[10:45] isolation, go right ahead, but I cannot really think of a proper use case at
[10:46] really think of a proper use case at this point. Other, of course, from
[10:48] this point. Other, of course, from posting slop on LinkedIn talking about
[10:50] posting slop on LinkedIn talking about my swarm of 50 agents rebuilding the
[10:52] my swarm of 50 agents rebuilding the web. Anyway, another Herder's big
[10:54] web. Anyway, another Herder's big selling point is its cross-platform.
[10:56] selling point is its cross-platform. Lots of projects claim the same, but
[10:58] Lots of projects claim the same, but again, same curl command and the same
[11:00] again, same curl command and the same 1-second run does the trick for my Linux
[11:03] 1-second run does the trick for my Linux box on my home lab. Herder runs and now
[11:05] box on my home lab. Herder runs and now I have Herder inside Herder inside Tmux,
[11:08] I have Herder inside Herder inside Tmux, which is a vortex of issues you'd
[11:10] which is a vortex of issues you'd probably want to avoid. Here's a clean
[11:12] probably want to avoid. Here's a clean setup on my remote machine, still in my
[11:14] setup on my remote machine, still in my Tmux, just for context of understanding
[11:17] Tmux, just for context of understanding where we're at. Now, the major thing
[11:19] where we're at. Now, the major thing about this is not the cross-platform
[11:20] about this is not the cross-platform support, the quick installation, and all
[11:22] support, the quick installation, and all that. These are all great, but they're
[11:24] that. These are all great, but they're not special. It's the unified experience
[11:26] not special. It's the unified experience with awesome features and awesome
[11:27] with awesome features and awesome defaults, from theme through layout and
[11:30] defaults, from theme through layout and binds to color coding and agent support
[11:32] binds to color coding and agent support out of the box everywhere. Beyond
[11:34] out of the box everywhere. Beyond everything else, Herder is easy and
[11:37] everything else, Herder is easy and that's something that I absolutely love.
[11:40] that's something that I absolutely love. Being allergic to software friction, it
[11:42] Being allergic to software friction, it slowly turns out as a real gem. It's a
[11:45] slowly turns out as a real gem. It's a beautiful opinionated multiplexer, if
[11:47] beautiful opinionated multiplexer, if nothing else. Now, here's another trick
[11:49] nothing else. Now, here's another trick it has up its sleeve. Up until now, I
[11:51] it has up its sleeve. Up until now, I was used to SSHing into my box, like so.
[11:54] was used to SSHing into my box, like so. Then, tmux [music] attach or Herder in
[11:56] Then, tmux [music] attach or Herder in our case and I get myself in for work.
[11:59] our case and I get myself in for work. Herder knows your SSH config and can
[12:01] Herder knows your SSH config and can connect remotely. Double hyphen remote
[12:03] connect remotely. Double hyphen remote box or your [music] IP and bam, we're
[12:06] box or your [music] IP and bam, we're in. Detach and you're back to your local
[12:09] in. Detach and you're back to your local shell. That's brilliant. And if you were
[12:11] shell. That's brilliant. And if you were wondering about these seemingly
[12:13] wondering about these seemingly clickable fold icons on the bottom of
[12:15] clickable fold icons on the bottom of our agents pane, yes, it collapses and
[12:17] our agents pane, yes, it collapses and you can have an even cleaner canvas to
[12:18] you can have an even cleaner canvas to work on. So, works perfectly on
[12:20] work on. So, works perfectly on localhost, just as perfect on my Linux
[12:22] localhost, just as perfect on my Linux box, but it's advertised as
[12:24] box, but it's advertised as mobile-friendly. Now, I'm not one to
[12:26] mobile-friendly. Now, I'm not one to believe anyone actually codes through
[12:27] believe anyone actually codes through their phone, but speaking to agents,
[12:30] their phone, but speaking to agents, absolutely. And while the next is
[12:32] absolutely. And while the next is doable, I still think the best way to
[12:34] doable, I still think the best way to achieve that is through Pi's Telegram
[12:36] achieve that is through Pi's Telegram gateway, which I've been using for
[12:37] gateway, which I've been using for months and you can find on the Pi agent
[12:39] months and you can find on the Pi agent video on the channel. All that said,
[12:41] video on the channel. All that said, check out the responsiveness of Herder.
[12:43] check out the responsiveness of Herder. No affiliation to Termius, but it just
[12:46] No affiliation to Termius, but it just works on iOS devices. SSH into the same
[12:48] works on iOS devices. SSH into the same box I have for my home lab and there I
[12:51] box I have for my home lab and there I am. Run Herder from my phone, auto
[12:53] am. Run Herder from my phone, auto completion, which is nice and boom, I'm
[12:55] completion, which is nice and boom, I'm in again. Now, responsive, sure, but I
[12:58] in again. Now, responsive, sure, but I mean, this is tiny. If anyone can do any
[13:01] mean, this is tiny. If anyone can do any kind of work like that, be my guest.
[13:03] kind of work like that, be my guest. Maybe on a landscape iPad with 13 in of
[13:06] Maybe on a landscape iPad with 13 in of a screen. Nevertheless, it works. I must
[13:09] a screen. Nevertheless, it works. I must say, I don't see the huge appeal here,
[13:11] say, I don't see the huge appeal here, but if you want, go right ahead. So,
[13:13] but if you want, go right ahead. So, back to our localhost. Maybe Codex is
[13:16] back to our localhost. Maybe Codex is malicious. I'm joking, please don't sue
[13:18] malicious. I'm joking, please don't sue me. Open code runs beautifully as well
[13:20] me. Open code runs beautifully as well and lists itself in the agents pane. If
[13:22] and lists itself in the agents pane. If you're unsure about your agent or run an
[13:24] you're unsure about your agent or run an even more obscure option than mine, then
[13:26] even more obscure option than mine, then the integration status on the CLI will
[13:29] the integration status on the CLI will tell you where you're at. You can rename
[13:31] tell you where you're at. You can rename agents like so. Now, this is kind of
[13:34] agents like so. Now, this is kind of hard to understand both because of the
[13:35] hard to understand both because of the complicated IDs and also the JSON
[13:38] complicated IDs and also the JSON results, and on top of all that, the
[13:39] results, and on top of all that, the mouse don't really save you here. You
[13:41] mouse don't really save you here. You can click around switching agents, which
[13:43] can click around switching agents, which is great. You can't rename them. So,
[13:44] is great. You can't rename them. So, Herder has a little bit of way to still
[13:46] Herder has a little bit of way to still go and rough edges to work on. What you
[13:48] go and rough edges to work on. What you can do, however, is attach directly to
[13:50] can do, however, is attach directly to an agent, kind of like skipping the
[13:52] an agent, kind of like skipping the entire UI {slash} layout and speaking
[13:54] entire UI {slash} layout and speaking directly to it. Herder agent attach to
[13:57] directly to it. Herder agent attach to the name, assuming you got it right, and
[13:59] the name, assuming you got it right, and you have it directly attached to a full
[14:01] you have it directly attached to a full window, no Herder UI inside. Okay, time
[14:04] window, no Herder UI inside. Okay, time to talk about configuration. It's not
[14:06] to talk about configuration. It's not hard to get that {dot} config {slash}
[14:08] hard to get that {dot} config {slash} Herder holds a config file, in this
[14:10] Herder holds a config file, in this instance, a terminal configuration that
[14:12] instance, a terminal configuration that can have all your preferences. Using the
[14:14] can have all your preferences. Using the CLI with the default config flag outputs
[14:17] CLI with the default config flag outputs a default file for you to get started. I
[14:19] a default file for you to get started. I can change all the standard settings,
[14:21] can change all the standard settings, including the prefix, which I'll try not
[14:23] including the prefix, which I'll try not to conflict with tmux at the moment. the
[14:26] to conflict with tmux at the moment. the configuration, you'd want to run it
[14:27] configuration, you'd want to run it through the CLI, to which you'll get a
[14:29] through the CLI, to which you'll get a response that approves or denies the
[14:30] response that approves or denies the change. Beyond standard bits, you can
[14:33] change. Beyond standard bits, you can actually turn keys into commands,
[14:35] actually turn keys into commands, initiating triggers, and that's really
[14:37] initiating triggers, and that's really cool. I can decide that prefix LG pops
[14:39] cool. I can decide that prefix LG pops lazy git. Hit the combo and boom, lazy
[14:42] lazy git. Hit the combo and boom, lazy git is in the house. To be fair, you can
[14:44] git is in the house. To be fair, you can basically do the same in tmux quite
[14:46] basically do the same in tmux quite easily. It's more about structuring the
[14:48] easily. It's more about structuring the configuration of every key, which makes
[14:50] configuration of every key, which makes things nicer to the user. Herder also
[14:52] things nicer to the user. Herder also comes with a handoff option, should you
[14:54] comes with a handoff option, should you want to transfer for a session and have
[14:56] want to transfer for a session and have it persist on a new or even remote
[14:58] it persist on a new or even remote server instead. You basically get the
[15:00] server instead. You basically get the server fully updated, create a new
[15:02] server fully updated, create a new session, and hand off the current
[15:03] session, and hand off the current running process to the new updated
[15:05] running process to the new updated version. You can do the same with a
[15:06] version. You can do the same with a remote machine by adding the remote flag
[15:09] remote machine by adding the remote flag and target. You get to keep the layout
[15:11] and target. You get to keep the layout and terminal history. One thing to keep
[15:13] and terminal history. One thing to keep in mind, though, is that this is only
[15:15] in mind, though, is that this is only relevant to Herder's own updater. If
[15:17] relevant to Herder's own updater. If you're using Homebrew, mix, or others,
[15:20] you're using Homebrew, mix, or others, they will be the ones that are updating,
[15:22] they will be the ones that are updating, and live handoff would just not work for
[15:24] and live handoff would just not work for obvious reasons. Say what you want, this
[15:26] obvious reasons. Say what you want, this is an amazing feature that's well
[15:28] is an amazing feature that's well thought out and to me is like tmux
[15:30] thought out and to me is like tmux resurrect but on steroids. The CLI goes
[15:32] resurrect but on steroids. The CLI goes on to offer a bunch of automation
[15:34] on to offer a bunch of automation options by handing you a list of tabs,
[15:36] options by handing you a list of tabs, creating or deleting existing ones,
[15:38] creating or deleting existing ones, listing workspaces and even panes and
[15:40] listing workspaces and even panes and even sending keys to the pane you like.
[15:42] even sending keys to the pane you like. Every option is a request that's sent to
[15:45] Every option is a request that's sent to an API and then gets a JSON response
[15:47] an API and then gets a JSON response with an error success with all the
[15:49] with an error success with all the relevant metadata. For context. Okay,
[15:51] relevant metadata. For context. Okay, the billion-dollar question. Am I
[15:53] the billion-dollar question. Am I keeping it? Well, as you've seen, it
[15:55] keeping it? Well, as you've seen, it still has it rough edges. Stuff that I
[15:58] still has it rough edges. Stuff that I love about tmux like jumping to the last
[16:00] love about tmux like jumping to the last tab or tmux floats, which is a plugin I
[16:02] tab or tmux floats, which is a plugin I built for floating panes, aren't
[16:03] built for floating panes, aren't available here. But it does make an
[16:05] available here. But it does make an extremely nicer out-of-the-box
[16:07] extremely nicer out-of-the-box multiplexing experience even without its
[16:09] multiplexing experience even without its agent capabilities. It has the user
[16:11] agent capabilities. It has the user experience in mind and makes an amazing
[16:14] experience in mind and makes an amazing package, especially for remote machines
[16:16] package, especially for remote machines but not only. For that reason, this is
[16:18] but not only. For that reason, this is exactly what I'll do. I'll keep tmux
[16:20] exactly what I'll do. I'll keep tmux locally for now and run herder as my
[16:21] locally for now and run herder as my daily driver on the home lab box where I
[16:24] daily driver on the home lab box where I do have actually agents. We'll see how
[16:26] do have actually agents. We'll see how it goes whether I find more edges or
[16:28] it goes whether I find more edges or more reasons to make the switch and go
[16:30] more reasons to make the switch and go with it for the long run. In the
[16:32] with it for the long run. In the meantime, if you want to set up your
[16:33] meantime, if you want to set up your tmux exactly like mine, go ahead and
[16:35] tmux exactly like mine, go ahead and catch this classic video on the channel.
[16:38] catch this classic video on the channel. Thank you for watching. I'll see you on
[16:39] Thank you for watching. I'll see you on the next one.
