MeterTab lives in your menu bar and shows your real-time token usage, spend, limits and resets — across Claude Code, the Anthropic & OpenAI APIs, Cursor, Codex and more. It’s the only usage meter your AI agents can talk to.
Tracks every provider you use
MeterTab ships a built-in MCP server. Point your coding agent at it and it can read your live budget mid-run — then downshift the model, or pause, before you hit the wall. No more “you’ve reached your limit” in the middle of a task.

MeterTab reads your AI tools’ own local logs (and, if you add a key, exact billing) and turns them into a meter you actually understand.
The 5-hour and weekly windows as a single “% used” ring, with the exact time to reset ticking down.
Tokens- and requests-per-minute, smoothed, so you can feel when a run is about to eat your window.
A GitHub-style history of your activity and spend. See your habits, your heavy days, your streaks.
A breakdown of where the money goes, by model and provider — Opus vs. Haiku vs. GPT, at a glance.
Add your own provider API key and MeterTab pulls real dollar spend from Anthropic, OpenAI & OpenRouter.
No backend, no account, no analytics. Your keys stay in the Keychain. Data Not Collected.
Pro unlocks native iPhone and Apple Watch apps, home-screen and Lock-Screen widgets, and a Watch complication — all syncing your Mac’s numbers over iCloud. Glance at your remaining headroom without touching your keyboard.
The gauge is free forever. Unlock everything with a single Universal Purchase.
One-time purchase on the Mac App Store. Universal across Mac, iPhone and Watch under the same Apple ID.
MeterTab reads the log files your AI CLIs already write on your Mac (Claude Code, Codex, Cursor). You grant a folder once; it’s read-only and never leaves your device. For exact dollar figures you can optionally add a provider API key, stored in the Keychain.
MeterTab exposes a local MCP server. Add it to your agent and it can call get_budget / should_continue mid-task to downshift models or pause before hitting a limit — so a long run survives your window instead of dying halfway.
Claude Code (first-class), the Anthropic and OpenAI APIs, OpenRouter, Codex, Cursor, Gemini, Groq and Together AI. The free tier tracks up to two; Pro is unlimited.
Yes. One non-consumable in-app purchase, no subscription, and it’s a Universal Purchase — buy it once and it unlocks on your Mac, iPhone and Watch under the same Apple ID. There’s a 14-day free trial.
No. There is no MeterTab backend. Keys live in the Keychain (this-device-only). The only data that syncs to your iPhone/Watch is token counts and percentages, over your private iCloud — never keys or message content.
macOS 14 Sonoma or later for the Mac app; iOS 17 / watchOS 10 for the companions. Universal (Apple Silicon & Intel).
