On Windows? Codex usage in the Windows taskbar: a native app for Windows 10 and 11, with alerts before you hit a limit.
Understanding Codex Usage Limits
OpenAI documents a five-hour limit for Plus and Standard Business (back for Plus since 25 August 2026; Pro plans currently have none) for local messages and cloud chats, and says weekly limits may also apply. Exact limits vary by plan and task. The authoritative values are the percentage used and reset time OpenAI reports for your account.
A usage limit can still interrupt active work. Because the limits OpenAI applies vary by account, plan, and task, check the provider-reported percentage and reset time instead of assuming a universal cap.
If those readings show Plus running out most days, whether to move to Pro is covered in is ChatGPT Pro worth it for Codex.
Do ChatGPT dots use your Codex limits?
Talking to a dot does not; the Codex work it starts does. Dots are OpenAI's always-on agents in ChatGPT, with their own cloud computer and browser. A dot can create Codex tasks on a computer you have connected, continue your existing local Codex tasks, and run cloud coding work in a Codex cloud environment you created. OpenAI's dots documentation (checked October 15, 2026) says conversations with your dot don't count toward your ChatGPT usage limits, but tasks your dot starts or manages in Codex count toward Codex usage limits as usual. Those tasks show up in the percentage OpenAI reports for your account, in /status and on the Codex usage page, even when you did not type the prompt yourself.
OpenAI also says plans with dots include an allowance for deeper work, with extended limits for the first month after launch. Dots are available on Pro 100, Pro 200 and Pro 500 for users over 18 outside the EEA, the UK and Switzerland, and are rolling out on Business Premium and Enterprise (off by default on Enterprise until an admin turns them on).
Method 1: Run /status inside Codex CLI
The fastest free check is the built-in slash command. Inside an active Codex CLI session, type:
/statusYou'll see the provider-reported percentage used and reset time for the limits OpenAI returns, along with session details such as the active model.
Limitations: /status only works while Codex is open and active: it's an on-demand snapshot, not an always-visible watch. You also have to remember to run it.
Method 2: OpenAI usage pages
Use the dashboard that matches what you are checking:
- Open chatgpt.com/codex/settings/usage for Codex subscription limits.
- Use platform.openai.com/usage only for metered API usage and spend.
- Run
/statusfor current limits in an active CLI session.
Important distinction: Codex subscription allowances and API billing are separate surfaces. Do not use the API usage dashboard as a substitute for the Codex usage page.
Method 3: Free CLI trackers such as ccusage
The open-source ccusage CLI supports Codex reports as well as Claude Code and other coding agents. Its current README documents ccusage codex daily.
For free checks, choose between OpenAI's Codex usage page, /status, and a terminal report such as ccusage. A menu-bar app is an optional always-visible interface.
Method 4: SessionWatcher (always-on, in your menu bar or taskbar)
Here's the friction the free options share: /status requires you to context-switch into Codex and remember to ask, while the usage pages require a browser tab. They are manual checks rather than an always-visible view.
SessionWatcher for Codex is a native app for the Mac menu bar and the Windows taskbar. It displays OpenAI-reported limit percentages and reset times, local session token totals, and estimated API-equivalent cost; that estimate is not actual ChatGPT subscription spend.
- Provider-reported limits. Percentage used and reset time for each limit OpenAI returns.
- Local token totals. Tokens recorded in local Codex session data.
- Estimated API-equivalent cost. A pricing estimate, not actual subscription spend.
- Optional desktop notifications. An app feature for reported usage; notifications do not control or prevent OpenAI limits.
- All supported tools in one app. Claude Code, Codex, Cursor, Copilot, Gemini CLI, Antigravity, opencode, Z.ai, Grok, OpenRouter, Devin, Kimi Code, and more.
Mostly waiting on the weekly limit? The Codex reset tracker is the same app pointed at reset times. Comparing apps, free ones included? See the best Codex usage trackers. Deciding between tools rather than trackers? Claude Code vs Codex compares their limits and prices.

How Codex reports usage windows
OpenAI's Codex pricing documentation, re-verified October 16, 2026, lists a five-hour limit for Plus and Standard Business (restored for Plus on 25 August 2026), says Pro plans currently have none, and says weekly limits may also apply. It does not document per-token rolling-return mechanics. Use /status or the Codex usage page for the percentage and reset time reported for your account.
Frequently Asked Questions
How do I check my Codex usage?
Run /status for current provider-reported limits, open chatgpt.com/codex/settings/usage for Codex subscription limits, or use SessionWatcher's menu bar Codex tracker for an always-visible view.
What happened to the Codex 5-hour rate limit window?
OpenAI suspended it on 12 July 2026 and restored it for Plus on 25 August 2026. Its Codex pricing documentation, re-verified October 16, 2026, lists a five-hour limit for Plus and Standard Business, says Pro plans currently have none, and says weekly limits may also apply. The full timeline is in the Codex 5-hour limit, explained. Exact limits vary by plan and task; check the percentage and reset time shown for your account.
Where is the Codex usage dashboard?
The official Codex subscription page is chatgpt.com/codex/settings/usage. platform.openai.com/usage is the separate API usage and spend dashboard.
Do ChatGPT dots count toward Codex usage limits?
Conversations with a dot don't count toward ChatGPT usage limits. Codex tasks the dot starts or manages count toward your Codex limits as usual, so they appear in /status and on the Codex usage page (OpenAI's dots documentation, checked October 15, 2026).
Why did my Codex stop working mid-session?
If Codex stops mid-session, check /status or the Codex usage page to see whether OpenAI has applied a usage limit to your account. SessionWatcher keeps reported usage visible and offers optional desktop notifications, but it does not control or prevent OpenAI limits.
Is there a free Codex usage monitor?
/status is built into Codex CLI and free. The official Codex usage page is also available, and the open-source ccusage CLI supports Codex reports. For an always-on Codex tracker, SessionWatcher is $6.99 one-time.
Does ccusage work with Codex?
Yes. The current ccusage README documents Codex reports, including ccusage codex daily.
Is there a Codex monitor app for macOS?
Yes. SessionWatcher for Codex is a native macOS menu bar app, also available for Windows 10 (2004+) and 11 in the taskbar (see SessionWatcher for Windows). $6.99 one-time, or Pro ($59 one-time, or $24/year) covering all supported tools. It shows provider-reported limits, local token totals, and estimated API-equivalent cost. One licence key works on Mac and Windows.
