A 48k-star project with a new face: the Herdr desktop app gets 2,000 stars in a week, stars you can't borrow

What it is: a desktop terminal window for people running several Claude Code or Codex sessions at once. One window manages agents across several machines, and the interface lets the agents modify it themselves.

Why it took off: the original command-line herdr already had 48k stars and a large base of long-time users. The official site's homepage was switched entirely to the desktop version, and with 367 points on HN's front page plus a round of press and videos, existing users starred it en masse. The timing also got ahead of Rex, a same-architecture product, going public.

CHow you could follow: stop building yet another agent terminal workbench. If there's a parent project, copy its migration playbook; if not, build mods within the herdr ecosystem, borrowing the look and name of a hot product (herdr-t3 got 139 stars in five days), or fill gaps long-time users keep complaining about, like session migration or mobile access.

Grade C: the stars come from the parent brand and existing users, which followers can't capture. The category is already held by Orca, T3 Code, and Rex. The only things that can be followed are ecosystem mods and small clients, and most get only dozens of stars, while big gaps can be absorbed by the official team at any time. Publicly known / widely discussed

Data (updated daily) · Repo created 2026-10-16 · 2,314 stars · 7 days +1,138: GitHub · stars
Data 2026-10-30 → 2026-11-08 (10 days, 10 observations). Points before 10-28 come from deeply / archive backfill, not every day has one

herdr-app is Herdr's new official desktop client, managing Claude Code and Codex running on several machines from one window. It launched in Oct 29 and reached 2,051 stars in a week (GitHub, 11-06). But this wasn't a new project growing on its own: behind it is an older project with 48k stars, nearly 2M installs, a YC batch spot, and a $6M seed round. For anyone trying to earn open-source stars, the useful part of this piece is how it moved old users onto a new product, and how much the plugin authors around it each got.

An HN post that wasn't by the author

On Oct 2026 30 00:42 (UTC), HN user cherioo posted a link titled "Herdr has released native app" pointing straight to the GitHub repo. The poster wasn't the author. The post ended up with 367 points and 271 comments.

The top comments were almost all from existing users. One person named flippant wrote: "I switched from tmux, which I'd used for ten years, to herdr this year and never looked back." Another found an easter egg: "There's a Windows 98 mode with Minesweeper, Solitaire, and Clippy!" Later he added: "Oh, and it can modify itself."

The day before the post, the repo had 65 stars. The snapshot the next day showed 832, a gain of 767 in one day.

What it is

In plain terms: a terminal window for people running several coding agents at once. If you run a few Claude Code or Codex sessions locally and across several SSH servers, herdr-app puts them all in one window, and the sidebar shows which are still running, which are stuck waiting for you, and which have finished. Close the window and the terminals keep running in the background, managed by a separate daemon called herdr-core.

Its hook is in the interface: the whole UI is a set of JavaScript mini-programs (officially called mods) that you can have an agent modify directly. The official homepage shows windows each redesigned by a user's agent, plus a Herdr 98 skin. Someone on HN called it "one of the best demos I've seen": "Other apps' themes only change colors and move things around; they don't conjure up a kanban board and cows wandering across the screen out of nothing."

Written in Rust, Apache-2.0 licensed, installable on Mac, Linux, and Windows.

Where the 2,000 stars came from

Date	Stars	What was happening at the time
10-29	—	Official launch; the official homepage was switched entirely to a desktop landing page, with the old command-line version moved to herdr.dev/tui
10-30	65	HN front page, 367 points
10-31	832(+767)	The HN wave landed the same day
11-01	1,176	heise, eesel.ai, Flavio Copes, and several YouTube reviews ("Herdr Desktop App Is INSANE") followed in turn
11-06	2,051	Daily gains dropped to 105, a typical launch spike followed by a long tail

(Star counts come from GitHub daily snapshots.)

The main cause is just one thing: old users migrating. The parent project, herdrdev/herdr, is a command-line version created in March and now at 48,283 stars. The official site shows nearly 1.97M installs and 2,009 community plugins. The author, Can (Ogulcan Celik), built it largely alone; in August it announced a YC batch, and in September a $6M seed round led by Bessemer. For a project of this size, when a new client ships, existing users starring it on the way is not a lot of stars: 2,000.

A supporting clue: as early as September, someone in the community had already built a desktop version of herdr with the same technology (penso/herdr-gpui, 2,128 stars), and it also gained 214 in a single day when the official version launched. The same crowd was clicking.

It also hit a specific timing window. Mitchell Hashimoto, creator of Ghostty, had a new company building Rex, an architecture nearly identical, which began invite-only Mac beta testing in Oct 5 and popularized the idea of "agent terminal + native window." Someone on HN said outright: "Feels like they wanted to get ahead of Rex." herdr-app got the same thing out as open source, on all platforms, before Rex's official release.

No sign of paid ads, a Product Hunt push, or star farming. About 15% of the stars are forks, with 190 open issues, suggesting real people are installing and modifying it.

Existing users are also complaining

In the same HN thread, there were plenty of unhappy voices, concentrated on one problem: the new and old versions don't interoperate. The new app runs on the new herdr-core and can't see sessions running in the old command-line version. One person wrote: "Other than the team and the name, the two have nothing in common." Others complained that all the keybindings changed; one found the panels empty after a laptop restart while the old version was fine; and another spent 10% of a week's quota having an agent write a mod just to switch the default shell to Homebrew's bash.

These show that 2,000 stars doesn't mean 2,000 users switched over. The official side hasn't published how many real installs the desktop version has.

Who it's competing with

This category has grown so large that someone on HN said "there are thirty million of them, and they all look the same":

Project	Stars	How herdr-app differs
Orca	117k, +6,524 in the last 7 days	A heavy workbench that organizes work by task and worktree, with a mobile app; some find it "too heavy and slow"
T3 Code	48k, +16,516 in the last 7 days	Skips the terminal and uses a chat-style interface
Superlogical Rex	Closed source, free	Nearly identical architecture, more polished, Mac only for now; both use the same agent state protocol
cmux	29k, +102 in the last 7 days	Mac only, no matter how many machines
Paseo, Conductor, vibe-kanban, claude-squad	9k to 29k	Most of them have mostly stopped climbing

On raw stars alone, Orca and T3 Code are an order of magnitude bigger than herdr-app, and they're also growing faster lately. herdr-app's 2,000 stars show that the Herdr brand has a loyal user base. They don't show it has won this category.

How many stars the people around it picked up

For anyone chasing stars, the more useful thing to look at is the third-party projects in the herdr ecosystem. In the week after the desktop release, a batch of mods and plugins suddenly appeared on GitHub (GitHub search, 11-06):

herdr-t3: reworked herdr-app into T3 Code's layout, 11-01 created, 139 stars. It borrowed another hot project's name.
Git Graph, the Redline code review tool, Cloudflare deploy status, agent viewing on mobile (herdr-anywhere), and a pixel RPG skin: each one got 28 to 33 stars.
Command-line versions built for the new core (hc-tui and similar): 11-04, 11-05 at least three people are building these, and all sit at 0 stars.

Earlier third-party clients (the mobile client Collie, the iOS client Heeler, and others) reached a few hundred to nearly 2,000 stars. The community desktop version, herdr-gpui, got 2,128 stars, and then the official version absorbed its feature requests.

The pattern is clear: riding a hot ecosystem can easily get you a few dozen stars. Getting to a thousand means filling a big gap ahead of the official team, and the official team could fill it themselves at any time.

If it were you

The one-line take: don't build yet another agent terminal workspace. herdr-app's stars came from its parent brand, not from you. What you can learn is its playbook, and what you can follow is the small gaps in its ecosystem. The ceiling is low.

Who this fits: people who already run an open-source project with several thousand stars and a stable user base and are deciding whether to ship a second-generation product, or people who want to spend a weekend getting a few dozen stars and build some reputation in the agent tooling crowd.

Who this doesn't fit: anyone hoping to build an agent desktop workspace from scratch and get to ten thousand stars with it. Orca and T3 Code are already here, Rex is backed by Ghostty's author, and the window has already closed.

How to do it:

If you have a parent project, copy its migration playbook: replace the whole homepage with the new product and move the old one to a subpath; have the install script handle dependencies too; and use a demo that shows the interface letting agents modify it as the launch hook, something people get at a glance.
Make customization itself the marketing: user-made skins and layouts go on the homepage, and every one of them is a share.
If you want to ride stars in the herdr ecosystem, don't build the command-line version everyone else is building (three people already are, and all sit at 0 stars). Follow the herdr-t3 approach: bring in the look of another hot product and put its name in yours. Or fill the gaps that long-time users complain about most: migrating old sessions, mobile, reconnecting after network drops.

How to get users (stars): when you post a mod, @ the official accounts in herdr's discussions and on X. If the official team reposts it, you get a wave. Put the borrowed hot project's name in yours (T3, Git Graph). A Show HN post does less than posting during the few days around the official team's next major release.

When the window is: the ecosystem's star-riding window follows the official release schedule. The peak is one to two weeks after the desktop release, and it clearly cools after mid-November. The moment Rex formally launches and opens its Windows version, the conversation will be taken by it.

Signs you've misread it: your mod has fewer than 20 stars two weeks after posting; the official team ships mobile or old-session migration itself and absorbs the gap you filled; or herdr-app's daily gains fall to single digits and the discussions go quiet, which means this ecosystem's heat has passed.

Why herdrdev/herdr-app took off

One line

herdr-app is Herdr's official native desktop client (Rust + GPUI, running on the new herdr-core daemon). It manages several terminal coding agents such as Claude Code and Codex in one window, and the interface itself can be modified by the agents. It didn't appear out of nowhere. It's the "second-generation client" from herdrdev/herdr, a project that already had 48k stars, claimed nearly 2M installs, got into YC, and raised a 6M seed round. The 2,000 stars mostly came from the parent project's existing users and one concentrated burst of exposure on launch day (official X announcement, HN front page, and a batch of secondary articles and videos). It isn't an independently breakout new product.

1. Basic data

Repo created 2026-10-16, officially released 2026-10-29. What we observed on the GitHub repo: 10-30 65 stars → 10-31 832 (+767) → 11-01 1,176 → 11-06 2,051 stars / 304 forks. Daily additions after launch fell from 767 steadily to 105, a classic launch spike followed by a long tail (source: GitHub repo_day).
Fork/star ratio is about 15%, slightly above the median for new repos of similar size (about 11%). The likely reason is that it's pitched as "copy the layout or mod and change it yourself." There are also 190 open issues, which suggests real people are using it. No suspicious signals.
The parent project herdrdev/herdr (TUI version) was created 2026-03-27. Wayback snapshots: 07-30 22,394 → 08-25 32,184 → 09-26 40,870 → 11-06 48,283 stars. The herdr.dev/tui page showed 1,967,496 installs and 2,009 community plugins (eesel.ai screenshot 2026-11-01). The same org also has herdr-core, with 410 stars.
The author is Can (Ogulcan Celik), who built it alone. 2026-08-06 he announced entry into YC F26 (at the time 25k stars and 340k downloads), and 2026-09-08 he announced a 6M seed round led by Bessemer (herdr.dev/blog).

2. Competitors

Product	Form	Launched	Scale	How herdr-app differs
Orca(stablyai/orca)	Open-source desktop ADE	2026-03	116,539 stars, +6,524 in the last 7 days	Task- and worktree-driven, feature-heavy, with mobile support. HN users said Orca was "too heavy and slow." herdr takes the approach of few primitives and free customization
T3 Code(pingdotgg/t3code)	Open-source GUI	2026-02	48,044 stars, +16,516 in the last 7 days	No longer talks to agents through a terminal. Uses a chat-style GUI with an official mobile app. herdr insists on "terminal-first"
Superlogical Rex	Closed-source native app, free	Announced 2026-07-29, 10-05 macOS public beta	Hashimoto's new company, launch post on HN with 796 points	Nearly identical architecture (a daemon holds the PTYs, plus GUI and CLI, and SSH remote). herdr-app's agent-state protocol, OSC 7501, was defined by Rex. Rex is more polished, herdr has more features, is open source, and runs on all platforms
cmux(manaflow-ai/cmux)	Open-source macOS terminal	2026-01	28,710 stars, only +102 in 7 days	Mac only, built on Ghostty, with a browser panel and notifications. No background persistence or multi-machine management like herdr's
Paseo(getpaseo/paseo)	Open-source desktop + mobile	2025-10	23,189 star	Focused on orchestrating from a phone. On the desktop side, people on HN have complained about memory blowups
Conductor	Closed-source Mac app	2025-07	Not verified	One task per workspace / branch, moving toward the cloud. herdr is local and LAN-first
Paradev (formerly Superset), vibe-kanban, claude-squad, agent-orchestrator	Open source	2025–2026	9k to 29k stars	Kanban and parallel orchestration tools, most of which have mostly stopped climbing (7 days +38 to +264)
tmux / Zellij	Long-established open-source multiplexer	2007 / 2020	50k / 36k stars	Doesn't know agent states, no agents dispatching each other
Community herdr GUI: penso/herdr-gpui	Open source	2026-09-20	2,128 star	The community built a desktop client for herdr on GPUI first, so the official app takes over that demand

Verdict: the space is crowded. By star count alone, Orca and T3 Code are an order of magnitude bigger than herdr-app and growing faster lately. So herdr-app getting 2,000 stars doesn't mean it won the category, only that the Herdr brand has a loyal user base.

3. Where users came from (growth tactics)

Existing users of the parent project migrating (main driver, confirmed): herdr.dev's homepage was swapped entirely for the app's landing page, with the TUI moved to herdr.dev/tui/; the app's install script also installs herdr-core. Many comments in the HN launch thread come from long-time users ("I've used herdr for months": mark_l_watson, shepherdjerred, monk_grilla, etc.).
Official X announcement (likely): Vibe Coding Radar captured a "BIG ANNOUNCEMENTS DAY" tweet from 10-29 (tweet id 2115841099575222765, author unverified). @herdrdev's earlier announcement of 0.9 got 4,381 likes (x-radar), so the account has real reach. Our X corpus only covers up to mid-September, so we don't have the launch tweet's numbers.
Hacker News front page (confirmed): "Herdr has released native app", posted 2026-10-30 00:42 UTC, 367 points, 271 comments, submitted by cherioo, not the author. The HN post landed before our 10-31 snapshot, matching the +767 peak. Herdr had already hit HN several times: 6-29 with 166 points, 7-02 with 404 points, and 8-06 with the YC announcement at 281 points.
Secondary coverage spread fast (confirmed): heise online English edition (11-02), Flavio Copes, eesel.ai, daily.dev, Nvdium, deniz.in, Glonce, MetaPatchAI, plus YouTube videos "Herdr Desktop App Is INSANE" and "Herdr's New Native Desktop App: Powerful and Gorgeous". On X, @Voxyz_ai posted a tutorial, "Claude Code + Herdr app with 10-31 workers", 10. Ecosystem players (Moshi, cmux) also published comparison pieces.
Ecosystem and plugin network effects: 2,009 community plugins, plus a circle of third-party clients (Collie, Heeler, Ovis, shepherdr, herdrm, and others ranging from a few hundred to nearly 2,000 stars). These developers naturally watch new herdr-core / app releases.
No paid ads, Product Hunt push, or star-buying found.

4. Why it took off

The brand and users were already there: a parent project with 48k stars and nearly 2M installs means a new client gets starred by existing users right away. The official app's star curve and the community herdr-gpui (which also spiked to +214 in a single day, 10-31) took off the same day, suggesting it's the same people.
Good timing: Rex 10-05 started its public beta and pushed the "agent terminal multiplexer + native GUI" pitch into the spotlight. An HN commenter flat-out said herdr "wanted to beat Rex to it." herdr-app shipped the same architecture first, open source and on every platform (Mac / Linux / Windows), before Rex's official launch.
Demand created by the TUI's ceiling: long-time users complained about the TUI's macOS text-selection bug, having to log in again after disconnects, and the inability to view diffs. The community had already built its own GPUI client (2,128 stars). The official app picks up exactly that demand.
The demo travels well: "your agent can rewrite the whole interface," "Herdr 98 (the Win98 skin includes Minesweeper and Clippy)," "every window on the homepage was built by a user's agent," and the homepage cites 427 mods. One HN commenter called it "one of the best demos I've seen."
Open source plus VC backing: Apache-2.0, YC, and Bessemer signal to developers that the project will be maintained over time. Some people, though, avoid it because it took VC money.

5. Differentiation

Versus Orca, T3 Code, and Conductor: herdr doesn't wrap agents or manage tasks for you; it handles only the terminal. Its primitives are few (machine → space → tab → pane → terminal), and the rest of the UI is JS mods that users and agents can change. Some compare it to Emacs.
Versus cmux: background persistence plus multiple SSH machines in one window, on all platforms.
Versus Rex: open source with more features and Windows / Linux support, but some on HN find Rex more polished, and both use the same status protocol (OSC 7501).
Is differentiation why it took off? Only partly. The main driver of 2,000 stars was the parent brand's existing users and the concentrated exposure on launch day. "A UI your agent can modify" gave the launch something to talk about and demo, but whether it would have taken off without the Herdr brand can't be proven. Conversely, the new app doesn't share sessions with the old TUI and can't see agents running in it, and long-time users are already complaining in HN and GitHub discussions, which could slow migration.

6. How many people know about it / follow the trend

Visibility: already widely discussed. HN front page at 367 points, heise coverage, multiple reviews, and YouTube videos. The parent project has disclosed funding (YC F26, a $6M Bessemer seed round). herdr is open source and free, so there's no public revenue.
Copycats and convergence: Superlogical Rex shares the same architecture and launched in the same period. The community also has penso/herdr-gpui, missuo/herdrm, powerfooI/roamgate (herdr-studio), devswha/ovis, and other GUI / web clients for herdr. The whole "agent desktop workbench" category is already crowded (Orca, T3 Code, Paseo, Conductor, Tern, and more).

7. What others can learn

Build core users and a plugin ecosystem with a lightweight, open-source TUI that works over SSH, then push the official GUI and swap the homepage entirely to the new product, so existing users migrate on their own.
"The UI is just files, have your agent change it": make customizability itself the demo, with a community gallery (users' layouts and mods hang directly on the homepage), so every user's creation spreads the product.
Make agent status an open protocol (OSC 7501) or socket API, so third-party agents and clients can plug in on their own.
Pair every major release with a blog post in the author's voice, and launch it on HN and X together.

8. Uncertain

Who posted the 10-29 launch tweet and its engagement (the X corpus only runs to mid-September, unverified).
How many real installs herdr-app has and how many TUI users actually migrated (no public figures).
Whether the official team will later unify the TUI and app on herdr-core; some on HN worry the TUI will be abandoned.
Whether 10-30's repo was already public (between repo creation and launch there were only 65 stars).
