A native macOS menu-bar app that forecasts your Claude Code, Codex, Grok and GitHub Copilot usage from your real history, so you know if you'll make it to reset. Usage history stays on your Mac, with no account or usage telemetry.
Where you stand right now: usage %, resets and countdowns for Codex and Claude Code.
Projects your week from your history to estimate when you'll run out, with what-if scenarios. 14-day free trial.
Reads Codex and Claude Code straight from your machine.
Your usage history stays on your Mac. No account or usage telemetry.
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.

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. ReserveGauge receives no usage data or usage telemetry.
Costs less than one stranded, mid-task limit hit.
For the Claude Code & Codex CLIs (terminal/IDE), not the claude.ai or ChatGPT web apps.

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. ReserveGauge receives no usage data or usage telemetry.
Free to download with the live gauge, forever. Pro (the forecasting engine) is £12.99 one-time with a 14-day free trial and free updates. If you buy and it's not for you, reply to your receipt within 14 days for a full refund.
Yes. One Pro licence activates on 2 Macs, so your laptop and desktop are both covered. Moving to a new Mac? Open ReserveGauge → Settings → Remove on the old one to free a seat. Need more than 2 Macs? Just buy another licence (£12.99) for the extra pair.
macOS 14 or later on Apple Silicon. It's a notarised native menu-bar app, about 3MB, installed from a DMG.
