Remodex

Remodex provides a bridge that lets a developer control a locally running Codex instance from an iPhone. The system consists of a Node.js bridge installed on a Mac and an iOS client; the bridge exposes Codex functionality while the phone sends commands, files, and skill references. Communication is secured with an X25519 key exchange and AES‑256‑GCM encryption, and pairing is performed by scanning a QR code, eliminating the need for accounts or cloud services.

The iOS app offers interactive modes for live steering of active runs, including fast and plan modes, and supports queuing follow‑up prompts without restarting Codex. It also implements a full Git workflow from the phone—commit, push, pull, branch, stash, and diff inspection—allowing developers to manage code directly from their pocket. Additional commands such as @files, $skills, and /subagents let users reference files, invoke custom skills, and spawn parallel agents.

Setup is a three‑step process: install the bridge via a single npm command, start it to display a QR code, and scan the code with the iPhone app. The bridge runs locally, keeping the repository on the developer’s machine, and all sessions are end‑to‑end encrypted with replay protection. Remodex is open source, experimental, and designed for developers who want secure, on‑device remote control of Codex without relying on external services.
