You meant ClaudeMeter. Missing one e.
"Claudmeter" is the most common misspelling of ClaudeMeter, a free open-source macOS menu bar app that shows your real Claude Pro and Max plan usage by reading the same server endpoint that claude.ai/settings/usage renders. Here is what it is, how to install it, and how it differs from ccusage.
The product is ClaudeMeter, spelled with an "e" after "Claud".
Domain: claude-meter.com. Source: github.com/m13v/claude-meter. Install: claude-meter.com/install. It runs as a menu bar app on macOS 12+ and a browser extension for Chrome, Arc, Brave, and Edge. MIT licensed, no telemetry.
What ClaudeMeter shows you that nothing else does
The claude.ai usage endpoint returns eight utilization floats. The Settings page renders four of them as bars. The other four pin to 1.0 with every visible bar still green; that is the silent 429 path. ClaudeMeter parses the full payload and renders all eight, plus the metered-overage balance, plus a per-bucket reset clock.
The four fields below the horizontal line (seven_day_oauth_apps, seven_day_omelette, seven_day_cowork, extra_usage) are the ones the Settings page hides. They are the most common source of the "rate limit reached" popup that arrives when your visible bars look fine.
Install in 30 seconds
1. brew install the menu bar app
brew install --cask m13v/tap/claude-meter. macOS 12 or newer. The cask tap is m13v/tap (Homebrew formula at github.com/m13v/homebrew-tap).
2. Load the browser extension once
Download the extension zip from https://github.com/m13v/claude-meter/releases. In chrome://extensions, enable Developer mode, Load unpacked, point at the unzipped folder. Pin the icon.
3. Visit claude.ai once
The extension calls /api/organizations/{org_uuid}/usage on a 1-minute alarm with your existing cookies. The menu bar lights up within a minute. No keychain prompt if the extension is the active source.
Other ways people spell it
For the record, the brand has been typed as "claudmeter", "claudemeter", "claude meter", "claude-meter", "clude meter", and "clawd meter" in real queries that reached this site. They all refer to the same project at claude-meter.com. The canonical spelling is ClaudeMeter (one word, two e's); the domain hyphenates because the unhyphenated one was taken.
"Clawd meter" is the phonetic one. Claude the model is pronounced "clawd" (it rhymes with "broad", not "loud"), so anyone who heard the name spoken in a video or a podcast before they ever saw it written tends to spell the tool "clawd meter". It is not a separate product. If you came here searching for "clawd meter", the tool you want is ClaudeMeter, the menu bar app and browser extension described above: brew install --cask m13v/tap/claude-meter, then load the extension.

ClaudeMeter vs ccusage in one paragraph
ccusage reads ~/.claude/projects/<project>/<session>.jsonl and sums input plus output tokens against a price card. It is the right tool for "what would these prompts have cost on the API?" ClaudeMeter reads the eight server-side utilization floats Anthropic actually enforces against your plan, the same numbers your Settings page shows. Local token sum and server plan quota are two different data sources. Most heavy users run both. The deeper comparison lives on /vs-ccusage.

Frequently asked questions
Is claudmeter a real product, or did I misspell it?
You missed one e. The product is ClaudeMeter, spelled c-l-a-u-d-e-m-e-t-e-r, hosted at claude-meter.com with the source at github.com/m13v/claude-meter. People type 'claudmeter' often enough that Google Search Console shows it as a recurring impression source for the real domain. Everything below uses the correct spelling.
What does ClaudeMeter actually do?
It is a free, open-source macOS menu bar app plus a browser extension. It reads the same JSON that claude.ai/settings/usage renders ('/api/organizations/{org_uuid}/usage') and shows you your rolling 5-hour window, your weekly quota, your Sonnet and Opus per-model weekly caps, and your extra-usage (metered overage) balance. The menu bar icon stays live; the popover gives you the numbers plus per-bucket reset clocks.
How do I install ClaudeMeter?
Two commands plus one click. (1) brew install --cask m13v/tap/claude-meter installs the menu bar app. (2) Open https://github.com/m13v/claude-meter/releases, download the extension zip, and Load unpacked in chrome://extensions. (3) Visit claude.ai once so the extension can call the usage endpoint with your existing cookies. Within a minute the menu bar lights up with your live numbers. Full instructions live at https://claude-meter.com/install.
Is ClaudeMeter free? What is the catch?
Free, MIT licensed, zero telemetry. The catch is that the claude.ai usage endpoint is undocumented; Anthropic could change the response shape and the project would need a one-line patch to src/models.rs to keep up. There is no paid tier, no account to make, no email to give. The single network destination is claude.ai itself, called once per minute on a chrome.alarms tick (POLL_MINUTES = 1 in extension/background.js).
ClaudeMeter vs ccusage, which one do I want?
They answer different questions, so most heavy users run both. ccusage reads ~/.claude/projects/<project>/<session>.jsonl and tells you what your Claude Code prompts would have cost at API token prices. ClaudeMeter reads the server-truth plan utilization floats that Anthropic enforces, the same numbers claude.ai/settings/usage shows you. Local token sum and server-side plan quota are different data sources for different decisions ('how much would I spend on API?' versus 'how close am I to a 429?').
Does ClaudeMeter work on Windows or Linux?
Not today. It is macOS 12+ for the menu bar binary (Rust core, SwiftUI shell). The browser extension itself is Chrome, Arc, Brave, and Edge; Safari is not supported because Manifest V3 sideload behavior differs there. A Windows or Linux port would mostly be a tray-icon shell on top of the existing Rust core. Open an issue on the GitHub repo if you want it.
What is the GitHub repo for ClaudeMeter?
github.com/m13v/claude-meter. The Rust core lives in src/, the SwiftUI menu bar shell in macos/, and the browser extension in extension/. README.md has the install steps and the undocumented usage-endpoint details. Issues and pull requests are welcome.
Is it spelled 'clawd meter' or 'claude meter'?
It is ClaudeMeter, c-l-a-u-d-e. 'Clawd meter' is a phonetic spelling: the model name Claude is pronounced 'clawd' (rhyming with 'broad'), so people who heard the name before they read it tend to write 'clawd'. There is no product called 'clawd meter'; it is the same free, open-source macOS menu bar app and browser extension at claude-meter.com. Search for 'clawd meter', 'claudmeter', or 'claude meter' and you land on the same project either way.
Does claudemeter need a password or my Anthropic API key?
Neither. The browser extension calls /api/organizations/{org_uuid}/usage with credentials: 'include', meaning it reuses the same session cookie your browser already has from being logged in to claude.ai. It POSTs the parsed snapshot to a loopback bridge on 127.0.0.1:63762 that only the menu bar app on your own machine can reach. No password, no API key, no manual cookie paste.
