Phone control for Codex
Pairs a phone to a Mac-hosted Codex session so instructions can be sent from mobile while responses stream back to the app.
Remodex
Remodex is an open-source bridge and mobile app for controlling Codex from your phone while execution stays on your Mac. iPhone-first, with an Android beta.
What Remodex is
Remodex is a local-first open-source bridge plus mobile app for controlling Codex from a phone. Codex still runs on your Mac; the app pairs over a secure session and sends instructions through the bridge while responses stream back in real time.
The basic setup is intentionally lightweight: install the bridge with `npm i -g remodex@latest`, run `remodex up`, then pair from the app by scanning the QR code shown inside the app. The source says you need Node.js 18+ and Codex CLI already installed and logged in on your Mac.
Core features
Secure paired session
Uses an authenticated end-to-end encrypted channel with X25519, Ed25519, AES-256-GCM, and replay protection after pairing.
Local execution on Mac
Runs Codex, git actions, and workspace actions on the Mac rather than on the phone, keeping execution local to the machine that already has the tooling.
Background bridge on macOS
Supports launchd-based background operation on macOS so the bridge can keep running after the terminal closes.
Git workflow controls
Includes local Git actions such as status, commit, push, pull, branch switching, stash, checkout, and log.
SSH from iPhone
Can open a native SSH session from the iPhone, with key material stored in the iOS Keychain.
Where it fits
Remote control while away from the desk
Use Remodex when you want to start, guide, or review Codex work from your phone instead of returning to the Mac for every prompt.
Mobile Git operations
Use it for local Git maintenance on the Mac when you only have your phone handy, such as checking status, switching branches, or pushing commits.
Phone-based SSH access
Use the SSH session feature when you need a shell connection from the phone and want the key material kept in the iOS Keychain.
Self-hosted or private-network setups
Use the self-hosting path if you want the relay under your own control or prefer a private-network setup such as Tailscale for iPhone access.
Android beta testing
Use the Android beta flow if you want to test the Android client while following the Google Group and Play testing enrollment steps in order.
Pros and Cons
Pros
- Lets you steer Codex from an iPhone while the actual execution stays on your Mac.
- Uses authenticated end-to-end encryption with replay protection after pairing.
- Supports practical local workflows, including Git operations and SSH access.
- Can keep the bridge alive on macOS through launchd after the terminal closes.
- Offers self-hosting options through a custom relay or local source checkout.
Cons
- The current source emphasizes iPhone support, while Android is presented as a beta.
- Codex must already be installed and working on the Mac before pairing; Remodex does not manage OpenAI credentials.
- The bridge runs on the Mac, so this is not a standalone mobile Codex client.

What do I need before I start?
You need Node.js 18 or newer, Codex CLI installed and already working on your Mac, and the Remodex iOS app on your iPhone. The source also says Android beta access is available through Google Groups and Google Play testing.
How do I install and pair it?
Install the bridge with `npm i -g remodex@latest`, then run `remodex up` on your Mac. Open the app, follow onboarding, and scan the QR code from inside the app.
Can I use Git or SSH from my phone?

Can I self-host Remodex?
Yes. The repo is described as self-host friendly, with support for setting `REMODEX_RELAY` to your own relay or using `./run-local-remodex.sh` from a source checkout. For iPhone self-hosting, Tailscale is recommended as the private-network path.
