I've been using Claude Code, Codex, Gemini (now Antigravity) at the same time for half year now, ever since I dipped my toe into agentic coding. I'd say in general Claude Code and Codex are equally powerful, Gemini is lagging behind.

One thing I appreciate with Codex is, OpenAI nowadays sometimes just gives you quota resets you can bank, so when you use up weekly quota before the week ends, you could just reset the quota, to continue using Codex. I've been much less anxious about Codex quota because of this perk. I just used one reset in the bank yesterday, and still have 3 resets left. Whereas with Claude, when you've used 95% quota 3 days before the week ends, you'd be much more anxious.

On the other hand, Claude Code's /remote-control mechanism is extremely helpful when I am running it in the cloud and wants to monitor it or control it on my phone. Codex currently doesn't support this kind of usage. Codex only allows you to use your phone to connect to a session on your desktop, not in the cloud.

Yes - Anthropic badly needs this same "here's a reset, use it when you want".

It's vastly better this way. Sure, it may impact the bottom line but it's a huge customer satisfaction win.

When Anthropic randomly resets me and I've only used 2%, that's worthless. When OpenAI tells me I have 3 resets available to use whenever I want - it's wonderful.

Codex is supported well on iPhone/iPad, it’s inside the ChatGPT app.

It’s amazing how much work you can get done on your phone now, especially if you already have a design mapped out in your head.

I have used claude and codex extensively but only from their CLI app (heavily sandboxed using rootless podman, network filtering, etc), so I don't really know what I'm missing with the GUI apps.

One killer feature that Claude has, and AFAIK Codex still lacks, is the ability to start a session in the terminal and then hand it off (actually just remotely control it), from the iOS app.

Last time I tried Codex on iOS it required a ton of set up to link a github project etc. The way claude lets me remote into a session I've already started on my actual machine is much better IMHO.

They’ve addressed that. Codex in the ChatGPT app on iOS is way better than Claude Code now.

You sign in the Codex app on your Mac same on iOS and are able to completely control your sessions - fork, side chats, plugins - everything.

It’s really great i often work through it. And you can connect any number of Codex instances on any number of macs and then manage them all through the iOS app.

maybe I'm misunderstanding but I don't want to sign into the app on a mac - I want to run the CLI on a headless linux server and control the sessions from my iPhone. Does Codex allow that now?

		You can do it too. There are two ways: 1. Run `codex remote-control --help` directly on your Linux server. 2. From the desktop app, connect to your Linux box, start Codex there, and make it remotely controllable. Either approach will get you set up.

Hmm, I don't have a desktop computer. I prefer my laptop be used for other purposes, and can sleep when not in use, instead of running a coding agent 24x7. That's why I prefer running coding agents in the cloud.

		You can do that too. Start working locally, then just do /handoff to transfer your session to the cloud and then work through the Codex app on your phone.

I've been using codex app server. Works great.

Hmm, thanks. Didn't know about this. But looks like a bunch of hassle to set it up?

if you don't want to hassle with it, use desktop app, you either can make it remote controllable or you can control other devboxes.

Finding the right docs/flags took longer than anything else. 15 mins from zero to productive on my phone.

		One thing I noticed you can't use codex installed via npm, but it will tell you that. Ymmv I'm a pretty simple user and do things in small manageable chunks. I try keep context < 10% before I fire off a task so I don't use many skills etc.
