Claude Code and Codex on your phone
Run Claude Code and Codex on your computer or server and use them from your phone: chat, approve commands and take voice calls in MausBot's free phone app.
MausBot runs the real Claude Code and Codex CLIs on your computer or server, on your own Claude or ChatGPT plan, and its iOS and Android companion apps let you use them from your phone. You message a bot, watch it work, answer its approval cards, and stop it if it goes wrong. MausBot is free and open source.

How it works
- Install MausBot on your computer, and sign in to Claude Code or Codex there, as you would in a terminal.
- Create a bot on Claude Code or Codex and give it a project folder.
- Pair the phone app by scanning the QR code in MausBot.
- Message the bot from your phone. When it asks to run a command or edit a file, the card shows on your phone: Allow or Deny.
What to know first
- The phone is a remote: Claude Code and Codex run on your computer, server or My Cloud, which has to be on.
- Sign in to Claude or ChatGPT on that computer, not on the phone. My Cloud needs its own sign-in once.
- Notifications arrive while the app is connected.
Frequently asked questions
- Is this the real Claude Code, or a copy?
- The real one. A Claude bot in MausBot runs the claude CLI on your machine, one process per thread, with your own login. A Codex bot runs the codex CLI the same way.
- Does it use my Claude Pro or Max plan?
- Yes. MausBot uses the login the CLI already has, so usage counts against your own plan or API key. Nothing goes through a MausBot account.
- Can I use Codex from my phone too?
- Yes. Codex bots work the same way, on your ChatGPT login or an OpenAI API key. One bot can be on Claude Code and the next on Codex.
- What if my laptop is closed?
- Then the phone can't reach it. On MausBot Cloud, from $15 a month, your bots run on My Cloud: sign in to Claude or ChatGPT there once, and your phone reaches them with your laptop closed.
