But what if the code is on my laptop? Alongside the tools needed to work with it

Case in point, I have a Rust project with a target/ directory with about 10GB. Compile times from scratch takes about 10 minutes. (I do not love this)

With this mobile app I need to upload the code to the cloud, right? Or does OpenAI expects me to compile huge projects on my phone?

No, the phone connects to your local device. This isn't "codex web" on mobile. Basically you work through your desktop on your phone. So to be clear, there are security risks (you can wipe your entire desktop from your phone).

Not if you use Linux; app not available yet.

The announcement doesn't make this very clear, but I think this talks to the Codex CLI, not the Codex App? (Or possibly both)

For now it appears that it talks only to the Codex App. Some users in this thread are saying that apparently the Codex CLI will support it on the next official release.

Codex App can connect to codex-cli via ssh. So you can use Codex App on a Mac with your projects/compilation etc. on Linux

You can run Codex Desktop on Linux. It's on AUR already. Granted, just a repacked ASAR from Windows version but still does work quite well. Haven't tested connection to mobile yet but the integration with cloud environments already works.

Not sure about how it works with Codex now, but with Claude you can just start a terminal session of claude code with your code checked out locally on your computer, and then enable remote control which lets you control that session from your phone.

So basically, it is like you are typing on your terminal on your computer from your phone.

basically yeah. the codex/claude desktop apps work the same way

The processes you're controlling are on your computer, similarly to Claude remote control.

I tried Codex web. It kinda sucks and OpenAI doesn't seem to be promoting it? Look elsewhere if you want a Linux VM in the cloud. (I quite like exe.dev and they do have good mobile support.)

It's beyond terrible. Like they're routing to gpt4o mini with low effort behind the scenes. Just let us pick the model and the effort.

I just use tailscale and remote desktop.
