VS Code: Account-Linked Cross-Device Session Sync

[darioringach]

I’d like to suggest adding an option for account-linked, cross-device session synchronization in the Codex VS Code extension. Specifically, it would be extremely valuable if chat history, editing context, and reasoning state could be securely persisted in the cloud and tied to a user’s OpenAI account rather than stored only locally. This would allow developers to seamlessly resume a Codex session on another machine (e.g., laptop, desktop, or remote environment) and maintain full conversational and architectural continuity within the same repository. Ideally, this would integrate natively into VS Code, automatically offering to resume synced sessions per workspace while still allowing users to opt out for privacy-sensitive projects. Such a feature would significantly improve multi-device workflows and align Codex with modern cloud-synced development practices.

@darioringach, if you'd like to suggest a feature, I recommend filling a feature request in our issue tracker (or upvoting an existing one). We generally prioritize features based on community upvotes.

Howdy, I implemented an experimental version of your feature. It requires a self-hosted linux server and syncs all of your codex sessions across all your enrolled devices. Its in experimental alpha at this stage

I ran into the same friction — working on one machine and wanting to check in on a session from another device. I didn't solve the full cross-device resume problem, but I built something that covers the "monitor and interact from another device" use case.

CodeVibe plugs into Codex CLI as a sidecar and streams the session to an iOS / Android app. You get the conversation history, tool calls, and approval prompts on your phone in real time. You can send prompts and approve file edits from there too.

It doesn't sync Codex's internal reasoning state or let you resume the full CLI on a different desktop — but if the main need is "I want to see what's happening and interact from my phone," it handles that.
