Herdr OS · for the Rabbit R1

Your agents,a herd inyour hand.

Herdr OS turns a Rabbit R1 into a pocket companion for every Claude Code, Codex, Pi and OpenCode coding agent on your machines. Glance at the herd, answer what's waiting, and talk back, without opening a laptop.

The herd

One sheep per agent. Wool in its maker's colors.

The plain sheep is the companion. It speaks for the herd; the branded ones speak for themselves. A sleeping sheep is idle, and the words always say so too.

Four rules

Orange is you.Your voice, your attention, anything waiting on you. Nothing else is ever orange.
Wheel moves. Button talks. Touch approves.Three controls, three jobs, no overlap, so muscle memory never sends the wrong thing.
A spoken yes never approves.Voice drafts, a finger decides. The side button can't answer a question by accident.
No invented numbers.Every model, token count and subagent comes from the agent's own session files. If nothing records it, the R1 doesn't show it.

01 · Glance

It sleeps until someone needs you.

The R1 rests on the lock screen with a quiet count of who is working. Wake it and the companion tells you, in one breath, what happened while you were away.

  • Asleep
  • Spoken briefing
  • Pasture

02 · Answer

Every question arrives as the sheep that asked it.

Approvals float above the agent in its own colors. Your choice glows orange, and the R1 names exactly where the answer goes before anything is sent.

  • Sheep asks
  • Bound to the question
  • Touch approves

03 · Talk

Hold the button. It answers out loud.

Walkie-talkie mode gives each agent a channel on the wheel. Your voice goes out in orange; its reply fills the screen in its brand color and is spoken back to you.

  • Push to talk
  • Channels on the wheel
  • Spoken replies

04 · Show it

Point at the whiteboard. The agent sees it.

Snap a photo with the R1's camera. It lands on the agent's own machine, next to the code, and the agent reads it like any file.

  • Camera
  • Saved where the code is
  • Thread

05 · Supervise

Subagents, tasks and a live terminal.

See every subagent's latest step, every background command's last lines, and the terminal itself, sanitized, scrollable on the wheel.

  • Subagents
  • Background tasks
  • Ghostty terminal

06 · Steer

Change models from your palm.

Pick Opus, Sonnet or GPT and the effort to match. Herdr OS types the harness's own command, so nothing is faked. Or say a new task and choose who takes it.

  • Model picker
  • Effort
  • New task

Every machine

Every agent. Every machine. One glance.

Past six agents the pasture folds into a flock per host. Tap one and it opens as its own field; turn the wheel and walk the whole flock.

Keeps time

The sky follows your clock.

Dawn, day, dusk and night. The sheep's colors and your orange never change with it; only the field does.

How it works

Reads the sourceEach harness's own files.

Model, effort, context, subagents, background commands and the conversation come from the session files and stores the agents already write.

Answers are boundTo the exact question.

Every decision carries a fingerprint of what you were shown. If the agent moved on, a stale answer is refused, not delivered.

Private by defaultNothing leaves your network.

The R1 pairs with a bridge you run, over your own Tailscale tailnet, with a one-time code and scoped tokens you can revoke.

From stock to herd

Your R1, from the box to Herdr OS.

Six steps, about forty minutes. Chrome does the flashing for you over USB: plug the R1 in and follow the installer. It erases the R1 and voids Rabbit's warranty, so it says so before every step that does.

Install from ChromeDownloads
  1. On the R1 and rabbit hole10 min
    Turn on developer mode and ask Rabbit to unlock

    In rabbit hole, under settings, r1, void the warranty to enable developer mode, then choose device modification, unlock. Rabbit's servers allow the unlock; nothing changes on the R1 yet.

  2. Chrome does it2 min
    Unlock the bootloader

    Plug in the powered-off R1. The installer catches its preloader, puts it in fastboot and unlocks it. This wipes the R1.

  3. Chrome does it10 min
    Flash LineageOS

    Turns verified boot off, wipes data the way Rabbit's restore does, removes Rabbit's launcher partition and writes the LineageOS GSI to the active slot.

  4. Chrome does it3 min
    Root with Magisk

    Patches the R1's own boot image with Magisk, on the R1, and flashes it back. You get the unpatched image as a download, to undo it.

  5. Chrome does it3 min
    Install Herdr OS

    Installs the Magisk module and the app, makes Herdr OS the home screen, sets the R1's defaults and reboots into the asleep screen.

  6. On your computer5 min
    Run the bridge, scan the code

    Install the bridge where Herdr runs and start it; `herdr-bridge enroll --tailscale --qr` prints a code the R1 scans. Your speech key goes in on the R1, never through the website.

    npm i -g @herdr-os/bridge && herdr-bridge serve --tailscale

Everything the installer sends.

The installer checks every file against these SHA-256 sums before it sends anything to your R1. Preview builds are signed with the developer's key; signed releases will update themselves.
