Codex Relay - Remote Codex App

Codex Relay is a third-party mobile companion for following a Codex workflow through a relay server running on a computer.

Our take

Consider for authorized local access to existing work.

Conversation views, follow-up prompts and approval responses connect phone review to an active desktop workflow.

Keep in mind: A running local server and network connection are required; this app is not an independent on-phone coding model or proof of OpenAI endorsement.

What you can do

  • Follow conversations and responses
  • Send follow-up prompts
  • Respond to input or approval requests
  • Attach images
  • Review workspace activity
  • Manage the connected relay

Good for

  • Developers already using a suitable local Codex setup

Consider alternatives for

  • Users expecting standalone code execution or included model access

Limitations & considerations

  • Captured minimum: iOS 16.4.
  • A running local server and network connection are required; this app is not an independent on-phone coding model or proof of OpenAI endorsement.

Privacy & permissions

The relay can expose code, images and action approvals; restrict server access to authorized devices and review each requested action.
