How to check your Codex usage.
Codex enforces two rate-limit windows, and running into one mid-task is the worst way to find out. Here are the three ways to see where you stand.
1. Run /status in the Codex CLI
Inside an active Codex session, type /status. It reports the remaining percentage for both windows, along with your current model and plan tier. This is the most direct check - but it only works while Codex is open, and you have to remember to run it. There is no passive display, and nothing warns you as a long-running task eats through the window.
2. Open the web usage dashboard
Your ChatGPT account's Codex settings include a usage page showing consumption against your plan. It's useful for the weekly picture, but it lives in a browser tab, lags behind real activity by a few minutes, and doesn't show your live position in the short rolling window - the one that actually interrupts sessions.
3. Keep it live in your menu bar
CodexBar Lite puts your current usage percentage in the macOS menu bar and updates it automatically. Click it for both windows - primary and secondary - with reset times and remaining credits, and get notified at 80%, 90%, exhaustion, and credit reset. No /status to remember, no dashboard tab to keep open.
It reads the session that codex login already created on your Mac (one file: ~/.codex/auth.json) and requests usage directly from chatgpt.com. No browser cookies, no Keychain, no API key, no account.
Which should you use?
| Method | Live? | Both windows? | Effort |
|---|---|---|---|
/status in the CLI | Point-in-time | Yes | Manual, per session |
| Web dashboard | Lags a few minutes | Partly | Manual, browser tab |
| CodexBar Lite menu bar | Yes, auto-refreshing | Yes, with alerts | None after install |
Free, open source, native, and minimal - your Codex login is enough.
