Keep Codex limits visible while you stay in the terminal

Codex fits the way many of us work: agent loops, shell commands, and long sessions without leaving the editor. The awkward part is checking how much quota remains. OpenAI exposes usage through authenticated endpoints, but finding them means breaking out of your flow — another tab, another login, another place to forget what you were doing.

Menu-bar monitoring for Codex

Token Gauge is a small, native menu-bar app for Mac — and the same app, on the same license, runs in the Windows system tray. It reads Codex's 5-hour and weekly rate-limits, plus token counts from the live endpoint and the local rollout logs, then shows rolling-window percentages, reset countdowns and status colors one click from whatever terminal session you're in. Switch tabs inside the popover to compare Codex with Claude, Cursor or any agent you run.

Numbers that help you plan sessions

Beyond the headline percentage, Token Gauge shows your rate-limit windows and per-model token breakdowns where OpenAI publishes them, so you can spot a heavy day before it burns a window. The reads happen on your machine and the latest values are kept locally with a timestamp, so you always know whether you're looking at a fresh poll or the last good one — no blank screen.

Unlock Codex with lifetime access

Claude Code is free without a license key. Codex, Cursor, Copilot and Antigravity come with the $7.99 lifetime license — one purchase, three devices, Mac and Windows, no subscription. Paste your key in Settings after checkout and every agent unlocks in the same popover. Codex is first-class because OpenAI exposes the rate-limit and token data we rely on, and we label any agent's fidelity honestly.

Token Gauge never reads your source code, prompts or chat history. Over the network it makes only OpenAI's own usage calls plus one Lemon Squeezy license check — that's the whole outbound surface. It isn't fully offline, but your code and prompts never leave the machine.

Codex usage tracking — FAQ

How does Token Gauge track Codex usage limits?

It reads Codex's 5-hour and weekly rate-limit windows plus token counts from the live endpoint and your local rollout logs — the same data Codex CLI itself uses — then shows live usage percentages, reset countdowns and per-model token breakdowns in the menu bar.

Does Token Gauge work with ChatGPT Plus and Pro Codex plans?

Yes. Token Gauge reads Codex usage through the same local session Codex CLI already creates on your machine, so it works with any ChatGPT or OpenAI plan that gives you Codex access — it shows whatever rate-limit windows and token counts your account exposes, with no separate login and no plan check of its own.

Does Token Gauge raise my Codex limits or get me more usage?

No. Token Gauge only reads and displays usage — it gives you visibility and timing, not more quota. It does not raise your limits or change your bill.

Is Codex usage tracking included in the free tier?

No. The free tier covers Claude Code only. Codex tracking comes with the $7.99 lifetime license, which also unlocks Cursor, Copilot and Antigravity — one purchase, three devices, Mac and Windows, no subscription.

Do I need to log in separately to see Codex usage in Token Gauge?

No. Token Gauge reads the local session and rollout logs that Codex CLI already creates on your machine, so once you're signed in to Codex CLI, usage shows up automatically — no extra login.
