A native macOS monitor for Codex CLI and Claude Code. See live limits, reset times and a forecast from local history, so you know if your current pace reaches reset. Grok and GitHub Copilot are included too. Usage history stays on your Mac.
See remaining allowance, reset times and countdowns for both providers.
Projects your week from your history to estimate when you'll run out, with what-if scenarios. No card required.
Reads Codex and Claude Code straight from your machine.
Your usage history stays on your Mac. Provider names, allowance values and usage history are not sent to ReserveGauge.
A live menu-bar dot shows when Claude Code and Codex are running, how many at once, and turns green when they finish.
Live 5-hour and weekly limits for Codex and Claude Code, straight off your Mac. No account, no setup.
It uses your historical usage patterns to forecast the rest of your week. It accounts for your daily rhythm, the hours you're asleep, and any recent spike in activity, so the projection matches how you work.
It shows whether your current pace lands you on, under, or over your limit, and warns you early if you're set to run out before the reset, so you can spend your full allowance and finish on the deadline.
Both providers, live gauges, the forecast chart, what-if scenarios and daily spend, one menu-bar click away.

If an account was depleted when you last used it, ReserveGauge keeps its last known usage and expected reset time visible. It can remind you when that expected reset is due.
ReserveGauge does not poll signed-out accounts or switch accounts. Expected reset times come from the last reading. Sign in to confirm current availability.

Tracks Claude Code (your terminal/IDE coding agent) and Codex, not the claude.ai chat app.
Works on Team & Enterprise Claude plans too: ReserveGauge tracks your personal Code allocation (e.g. Max 5x). The shared team pool isn't shown, as Anthropic doesn't expose it to the app.
ReserveGauge reads limits from the providers' own APIs using the login already on your Mac, then computes and stores your usage history locally. Provider credentials go only to that provider. Provider names, allowance values and usage history are not sent to ReserveGauge.

Tracks the Claude Code and Codex coding agents in your terminal or IDE. It does not track the claude.ai or ChatGPT web apps, those are separate products the providers don't expose usage for.
OpenAI Codex, Anthropic Claude Code, xAI Grok and GitHub Copilot are live today (Codex and Claude Code with their 5-hour and weekly limits, Grok with your monthly credit usage, Copilot with your monthly premium requests). Cursor is planned.
Gemini's limits are server-side and the Gemini CLI doesn't expose a usage or quota endpoint we can read locally, so there's nothing to forecast. We'll add it if Google exposes that data.
No. ReserveGauge tracks Claude Code and Codex, the coding agents in your terminal or IDE. The claude.ai chat app and the ChatGPT website are separate products on separate meters, and the providers don't expose that usage to apps. If you only use the Claude or ChatGPT website, ReserveGauge won't show any usage.
Yes, it works on Team and Enterprise plans, tracking your personal Claude Code allocation (e.g. Max 5x). The shared team pool isn't shown, as Anthropic doesn't expose pooled usage to the app.
Yes. ReserveGauge reads your limits directly from the providers' own APIs using the login already on your Mac, then computes and stores your usage history locally. Provider credentials go only to that provider. Provider names, allowance values and usage history are not sent to ReserveGauge.
