Switching agents and models inside one task

Run one command, scan with your phone, and keep coding from anywhere.

npx opentandem@latest remote

Quick start

1. Run this on the computer where your coding agents live. It can be your laptop, a Mac mini
under the desk, or a Linux server you reach over SSH.

npx opentandem@latest remote

No Node.js on that computer? Use the installer instead:

# macOS and Linux
curl -fsSL https://opentandem.org/install.sh -o install.sh
sh install.sh remote

# Windows PowerShell
irm https://opentandem.org/install.ps1 | iex; opentandem remote

2. Scan the QR code with your phone. Sign in with your email and tap Allow to connect this computer.

$ npx opentandem@latest remote

  OpenTandem
  Scan with your phone to sign in and allow this computer:

  Waiting for your phone… (valid for 10 minutes)
  ✓ Connected to "My workspace" as MacBook-Pro
  ✓ Runs in the background and starts with your computer

3. Send a task from your phone. Open OpenTandem, pick this computer, a project folder and an
agent, and send. The agent runs on your computer; you follow its progress and open its files on the phone.

Every run updates OpenTandem to the latest version first, so there is nothing else to keep up to date.

What you get

OpenTandem starts the agent CLIs already installed on your computer, signed in with your own accounts,
inside your own project folders. All 18 agents listed at the top are supported.

Choose the right agent for the next run.

_{Agent and model switching}

Switch between supported agents and their available models from the task composer, as shown above.
The task keeps its conversation and outputs.

Switch agents and models in one place
Models reported by the connected Runner
Live quota visible beside each agent

Move to your phone and keep working on the same task.

_{Mobile and artifacts}

Mobile gives you the same task controls as desktop: continue the conversation, switch agents, track execution, and open generated images, documents, and HTML pages.

Keep the same task and context
Switch agents and models
Track progress and open outputs

Continuing a task from a phone

Know which machine is ready before you assign the task.

_{Multi-machine orchestration}

OpenTandem shows connected Runners and their live status. Send work to the machine that already has the right repository, tools, and environment.

Runner availability in real time
Project environment stays on the selected machine
One workspace tracks every execution

Choosing a ready machine for a task

Manage tasks, conversations, and outputs in one place.

_{Task management}

Organize work by project, keep conversations saved and archived, pin important tasks for follow-up, and open generated work from any device.

Organize tasks by project
Save, archive, and pin conversations
Preview task outputs across devices

Opening task outputs

Share tasks, execution progress, and finished work.

_{Team collaboration}

Projects and tasks live inside a workspace with team access. Other members can continue the same execution without rebuilding its context in another conversation.

Workspace and member management
Shared projects and task progress
Conversations and finished work in one place

Commands

Command	What it does
`opentandem remote`	Connect this computer by scanning a QR code with your phone. When it is already connected, it says so and shows a QR code that opens OpenTandem on your phone.
`opentandem list`	The Runners on this computer (one per workspace), their ids, and whether each is online.
`opentandem stop` · `start` · `restart` `[<id> \| all]`	Stop, start or restart one Runner by id (the first few characters are enough). With a single Runner the id can be left out; with several, it lists them and asks. `all` acts on the whole background service: `start all` also turns on start at login, `stop all` turns it off.
`opentandem logs [<id>] [-f]`	Show the latest log lines, or follow them.
`opentandem update`	Update the CLI and the Runner now and restart the service.
`opentandem uninstall`	Remove the service and the program. Your local conversation history stays.

Other ways to connect

Way	When to use it
Desktop app for Mac	You prefer a window over the terminal. Sign in and choose Connect.
Settings → Computers → Add a computer in the web app	You are already signed in on the web and want to copy a command for another computer.

Note for AI agents: you may run npx opentandem@latest remote for the person you are helping,
but only they can scan the QR code, sign in and allow the computer. Show them the QR code or the
link and wait. Never try to complete the sign-in yourself.
