Claude Code Remote Control, and other ways to use Claude Code from your phone

How Claude Code's Remote Control works, what it needs, and three other ways to reach your coding agents from a phone, including Codex and other agents.

The same Claude Code session on a computer and on a phone, through the Mirasim phone appThe same Claude Code session on a computer and on a phone, through the Mirasim phone app

The short answer

Remote Control is a Claude Code feature from Anthropic. It connects claude.ai/code or the Claude app for iOS and Android to a Claude Code session running on your computer, so you can start a task at your desk and pick it up on your phone. Claude Code keeps running on your computer the whole time.

  1. Start it on the computer

    claude --rc, claude remote-control, or /rc in a running session

  2. Open it on the phone

    Scan the QR code, or find the session in the Claude app or claude.ai/code

  3. Keep the computer on

    The phone is a window into the session on your computer

claude remote-control runs as a server that waits for connections and shows a QR code when you press the spacebar; claude --rc is a normal session you can also type into locally.

What Remote Control needs

  • A Claude Pro, Max, Ultra, Team or Enterprise plan. API keys are not supported.
  • On Team and Enterprise, an Owner turns it on first in Claude Code's admin settings.
  • Claude Code talking to Anthropic directly: it isn't available through Amazon Bedrock, Google Cloud's Agent Platform or Microsoft Foundry, or when ANTHROPIC_BASE_URL points at a gateway or proxy.
  • Your computer on, with the claude process running. If the laptop sleeps or the network drops, it reconnects when the computer is back.

Four ways to use a coding agent from your phone

Where the agent runsWhat you needAgents
Remote ControlYour computerA Claude subscription and the Claude app or claude.ai/codeClaude Code
Claude Code on the webAnthropic's cloudA Claude subscription and the Claude app or a browserClaude Code
SSH from a phone terminalYour computer or serverA terminal app on the phone and a way to reach the machineAny terminal agent
Mirasim phone appYour computer, or a team space we hostA Mirasim account; your Claude or ChatGPT sign-in, API keys or Mirasim creditClaude Code, Codex, Kimi Code and seven more

Claude Code on the web runs in Anthropic's cloud rather than on your computer, so you can start long tasks with your computer off and check back later.

Using Mirasim's phone app

  1. Make the computer a collab space

    Free; only an end-to-end encrypted relay channel is opened

  2. Install the phone app

    Android APK, or iPhone through TestFlight; sign in with the same account

  3. Pick the computer

    Its sessions are there, from every agent

On the phone you can read sessions, send messages, images and files, answer the agent's questions and permission requests, and get notified when your turn finishes.

The code stays on your computer, no ports need opening, and the phone doesn't have to be on the same Wi-Fi. Mirasim can keep the computer awake while tasks run, and a team space we host keeps running after you close your laptop.

Questions

Can I use Remote Control with an API key?
No. Anthropic lists Pro, Max, Ultra, Team and Enterprise plans, and says API keys are not supported.
Does Remote Control work for Codex?
No, it's a Claude Code feature. To follow Codex and Claude Code sessions from the same phone, use the Mirasim phone app.
Does my computer need to stay on?
For Remote Control and for Mirasim on your own computer, yes. Claude Code on the web and a Mirasim team space we host keep running without it.
Can teammates follow the same session from their phones?
In Mirasim, yes: turn on Share with members and teammates send into the same session. Personal Claude and ChatGPT subscriptions are for their owner only, so a shared session runs on a shared key or space credit.
