Mussh

For the coding agents you run in Herdr

Separate chats for your coding agents.

10 coding agents each get their own chat on your phone. Read replies, answer approval requests and check project diffs without digging through terminals.

Android and iPhone. Chat needs Herdr, the runtime your coding agents run on.

The chat screen: you ask Claude Code why the checkout test fails on CI; it edits the cart code, runs the tests and explains the float rounding fix with a code snippet. Asked for the result, it replies that 14 of 14 tests pass.

27 supported agents. 10 have a chat view on Android and iPhone; the others have fleet status and a live terminal. See the full list.

Read the agent, not the scrollback

Most of the time you only need to read an answer, approve a command or look at a diff. These are the screens for that.

The fleet screen for the host studio: one agent waiting for an approval and one done under Waiting for you, then two working and two idle, grouped by status.

1 / 4 · Fleet

Every agent at a glance

See who's waiting for you, who's working and who's done. Open an agent's chat or live terminal from your fleet.

An approval panel over the chat: the agent asks to run the webhook tests with npm test, with the options Yes, Yes and always allow access to the project folder, and No.

2 / 4 · Approvals

Approve with one tap

Read the permission request and answer it. The app only sends your answer if the question is still on screen.

The review changes screen: three changed files with 14 lines added and 5 removed; cart.ts is expanded to show the integer-cents fix.

3 / 4 · Changes

Changes, file by file

Check added and removed lines before you send the next prompt. Browse files and git history without changing the repository.

The terminal on the host studio: git log and git status in colour, with Esc, Ctrl, Tab and arrow keys below.

4 / 4 · Live terminal

The terminal, when you want it

Open the agent's own terminal in colour, with Esc, Tab, Ctrl-C and arrow keys. Pinch to change the font size.

Take a look around

Swipe between screens, or focus the screenshot and use the left and right arrow keys. You can also choose a screen by name. Nothing advances automatically.

Keep the work moving

Tools for the next prompt, the next decision and the work in between. Available on Android and iPhone.

  • Listen to an answer

    Read answers aloud with your phone's system voice. Pause, resume or stop, and optionally read new completed answers automatically while the chat is open.

    See the voice controls

  • Fleet notifications

    See which agent needs you and open it from a notification while the app keeps its connection. These aren't push alerts when the app is closed.

    Open a notification

  • Readable chat

    Messages, Markdown and code for 10 agents. Tool calls fold into a line with their result.

    Follow a conversation Queue a follow-up

  • Photos in your prompt

    Attach photos from your camera, gallery, files or clipboard. See the thumbnails before sending; uploads go straight to your own computer over SSH.

    Preview an attachment

  • Terminal and real keys

    Use a full-colour SSH terminal and the agent's live panel, with Esc, Tab, Ctrl-C and arrow keys on hand.

    Open the key panel

  • Review the changes

    Open changed files and their diffs, with line numbers and added or removed lines. Review without editing files or changing the checkout.

    Inspect a real diff

  • A file reader, not just a file list

    Read Markdown, highlighted code and diffs, view images, and check recent commits without changing the agent's files.

    Explore the file reader

  • Pair with one QR code

    Run the app's pairing command on your computer and scan its code. Confirm the phone's key before connecting. Pairing supports Linux, macOS and Windows.

  • Dictate a prompt

    Speak into your phone's own speech recognition instead of typing. Edit the text before sending; the microphone is only on while you dictate.

    Find the microphone

  • Your own computers

    Fleet, approvals, chat, files and change review on Linux, macOS and Windows. Windows uses its own OpenSSH Server, without WSL.

    Connect your computer

  • Switch projects and agents

    Find workspaces, tabs and sessions in the drawer. See the project's git state and switch chats without moving the view on your computer.

    See the workspace drawer

  • Make it comfortable to read

Connected in three steps

  1. Install Herdr and the app

    Herdr keeps your coding agents running on your computer and shows which one needs you. Install Herdr on your computer, keep it running and turn on the SSH server. Get Mussh from Google Play or the App Store.

  2. Scan the QR code

    Copy the pairing command from the app, run it on your computer and scan the code. Confirm the phone's key there and you're in. On Windows the command runs in PowerShell.

  3. Talk to your agents

    Open your fleet, tap an agent and chat. Answer its questions, check the changes, and open the terminal when you want to see everything.

Your machine, your key. The app talks to your computer over SSH. The phone's key never leaves the phone, and you can revoke it from your computer at any time. There's no Mussh account and no server in between.
