Feature request: Cross-device sync for Codex Projects and Chats #21803

Description

What feature are you requesting?

I would like Codex to support cross-device continuity for Projects and Chats when signed in with the same OpenAI account.

For example, I use Codex across two Mac computers. Ideally, I could start a Codex Project or Chat on one Mac, then open Codex on another Mac with the same account and continue the same Project or Chat from where I left off.

Why is this useful?

Many developers regularly switch between a desktop and a laptop. Today, Codex sessions and project context feel tied to the local machine, which means switching devices requires manually recreating context, syncing notes, or relying on external workarounds.

My ideal experience would be similar to ChatGPT conversation continuity: recent Codex Projects, Chats, task state, and high-level working context would be available across trusted devices.

I understand that local filesystem paths, repositories, terminal state, and approval settings may need to remain device-specific. But it would still be very valuable to sync or restore:

  • Conversation history
  • Project metadata
  • Current task state
  • Recent working context
  • Associated repository information
  • Session summaries or checkpoints

Possible implementation options

A native account-level sync feature would be ideal.

If full native sync is not currently planned, I would also be grateful for any official API, SDK, MCP integration, or supported import/export mechanism that would allow users to build this functionality themselves.

For example, an official way to access, export, restore, or synchronize Codex sessions across trusted devices would make it possible to build a personal “session hub” or workflow manager around Codex.

This request is related to, but more specifically focused on cross-device Codex continuity:

Additional context

Thank you for building Codex. It has been very helpful, and cross-device continuity would make it much smoother for users who regularly move between multiple computers.
