How to check your Claude Code and Codex usage limits
Short answer: Claude Code and Codex each have a 5-hour limit and a weekly limit. You can check them inside each tool, or keep both on screen with Pikori, a free Mac menu bar app.
The two limits
On a Claude subscription, Claude Code shares a 5-hour limit that starts with your first message and a weekly limit across all your sessions. Codex works the same way on a ChatGPT plan: a short limit that refills every few hours, and a weekly one.
The limits are measured as a share of your plan, not as a token count. That is why counting tokens in local log files rarely matches what the tools tell you.
Check them inside the tools
- Claude Code: run
/usagein a session to see how much of each limit you have used and when it resets. - Codex CLI: run
/statusto see your current limits.
Both only tell you when you ask. If you work in long sessions, it is easy to hit the limit in the middle of a task.
Keep both in your menu bar
Pikori shows both limits for Claude Code and Codex in one panel, next to your clock:
- What is left of the 5-hour and weekly limits, as bars, with the exact reset time.
- Codex limits are read from the Codex app on your Mac every 30 seconds, so an early reset shows up quickly.
- Claude limits come from Claude Code's own status line, the same numbers Claude Code uses.
- A notification when a limit drops to 10%.
- Old readings fade and show their age, so you never mistake a stale number for a live one.
Everything stays on your Mac. Pikori has no account and no analytics. It is free, for macOS 13 or later on Apple silicon and Intel.
Why Pikori and claude.ai show different numbers
Pikori shows what is left by default; claude.ai shows what is used. 65% left is 35% used. You can switch Pikori to show usage in Settings. Use on the website shows up in Pikori after your next Claude Code message.
