Your usage stays on your Mac.
WhatsMyUsage reads the logins your AI tools already keep and asks each vendor for your usage. It keeps raw readings for 30 days and daily summaries for 13 months, in plain files on your Mac. There's no WhatsMyUsage account, and no WhatsMyUsage server in between.
No WhatsMyUsage server
Your Mac asks each vendor directly, so your logins and usage never pass through us. Crash reports go to Sentry unless you turn them off in Settings › General.
Reads your existing logins
Credentials are read where your tools keep them, and token counts come from your agents' own records. Logins go only to the vendor they belong to. API keys you enter are kept in your Keychain.
No account
Nothing to sign up for. Install it and connect your agents.
History you can clear
Raw readings are kept 30 days, daily summaries 13 months. They survive updates and removing an agent; Settings › General › Clear usage history… deletes them.
Questions
What does WhatsMyUsage do?
It puts the usage limits of your AI tools in your Mac's menu bar: how much is left, when each limit resets, and whether you're on pace to run out first. It can warn you before that happens.
Which agents does it support?
68 in total. Claude, Codex, Cursor and Grok Build have dedicated integrations. 64 more, from Copilot and Gemini to OpenRouter, connect through the login your tool keeps on your Mac, a browser session, or an API key. Search the full list in the first step, at the top of the page.
How do the warnings work?
WhatsMyUsage records how fast each limit drains and projects when it will run out. If that's before the reset, you get a warning 15, 30 or 60 minutes ahead. It also tells you when paid extra usage starts and when a capped limit is back. All three are on from the start, and macOS asks for permission the first time you open the panel. Quiet hours, off unless you turn them on, pause alerts from 22:00 to 08:00.
What do the dollar amounts mean?
Credits and extra balances are the amounts your provider reports. API value in Stats is what your tokens would have cost at each model's API prices, cached input included, so you can see what your plan is worth to you. Where a provider doesn't report dollars, WhatsMyUsage estimates them from pay-as-you-go rates. Treat those as orientation, not a bill.
What are the system requirements?
macOS 14 Sonoma or later, on Apple silicon or Intel.
Where does my usage data come from?
From your Mac. The app reads the credentials your tools already store and asks each vendor's own usage endpoint for the same numbers their dashboards show. Token counts come from the logs Claude Code, Codex and Grok Build keep on your Mac, including Codex's compressed archives, and from your Cursor account's usage events. Your logins and usage never pass through a WhatsMyUsage server.
How long is my history kept?
Raw readings for 30 days, which pace forecasts need, and one summary per agent per day for 13 months, which Stats use. Both stay in ~/Library/Application Support/WhatsMyUsage and survive updates, reconnects and removing an agent. Settings › General › Clear usage history… deletes them.
Do I need to create an account?
No. There's no sign-up and no WhatsMyUsage cloud. Install it and connect your agents.
Why pay when free trackers exist?
Free trackers exist, and they're good. WhatsMyUsage is for people who want the answer, not the setup. It warns you 15, 30 or 60 minutes before a limit runs out, timed from your own pace, and tells you the moment a limit is hit and paid extra usage starts. Its settings come with defaults that are already right. It's $4.99 once with no account, support is an email to the developer, and direct purchases can be refunded within 14 days.
Is there a free trial?
No. The window at the top of this page shows the app's own panel on your setup, and if it's not for you, direct purchases get a full refund within 14 days.
How do I buy it?
Buy it here for $4.99 as a one-time purchase through Polar, or on the Setapp store for the same price with no Setapp membership. A direct purchase comes with a license key for one Mac at a time. To move it to a new Mac, deactivate the old one in Settings.
Can I get a refund?
Yes. Email contact@getwhatsmyusage.com within 14 days of a direct purchase for a full refund. Setapp purchases follow Setapp's refund policy.
