Show HN: Claudeometer – Share and pool Claude usage across a team (macOS, OSS)

A developer released Claudeometer, an open-source macOS menu-bar app that displays live Claude AI usage quotas and burn rates. The app also enables team sharing and quota borrowing through a self-hosted relay, with end-to-end encryption for credentials.

A native macOS menu-bar app that shows your Claude usage like a battery — live quota, burn rate, and graduated alerts so you never get surprised by a limit. ⌁ 62% 🙂 ← in your menu bar, color shifts green → red as you climb Live quota in the menu bar — the 5-hour rolling window as a percentage, with a mood emoji and a color that gradually shifts from green to red as usage climbs. Detailed popover — click the menu-bar icon for:- the 5-hour window hero with burn rate +X%/hr and an ETA to full, 7-day , Sonnet , Opus , and OAuth apps quotas,- a 24-hour pace sparkline built from locally-stored history , Claude Code · Hot sessions — your most token-heavy sessions in the last 5h,- extra-usage spend when enabled . - the Graduated notifications — alerts at 50% , 75% , 90% panic , and 100% of the 5-hour window, each firing once per window. Local history — usage snapshots are stored locally for up to 30 days ~/Library/Application Support/Claudeometer/history.json and pruned automatically. Everything stays on your machine. The app sends no telemetry anywhere. brew tap SGSI/claudeometer brew trust sgsi/claudeometer one-time: Homebrew 6.0+ requires trusting third-party taps brew install --cask claudeometer Homebrew clears the macOS quarantine flag during install, so the app opens with no Gatekeeper warning . Download the latest Claudeometer.dmg from the releases page https://github.com/SGSI/claudeometer/releases/latest , open it, and drag Claudeometer to Applications . The app is not yet signed/notarized, so a raw download triggers macOS Gatekeeper on first launch. To get past it, run once: xattr -dr com.apple.quarantine /Applications/Claudeometer.app …or try to open it, then go to System Settings → Privacy & Security → Open Anyway . On first launch macOS may ask for access to the Claude Code-credentials Keychain item — allow it. If the app says the token is expired, click Login in the ••• menu or run claude in a terminal once. Claudeometer reads the OAuth token that Claude Code stores in the macOS Keychain under Claude Code-credentials , then calls: https://api.anthropic.com/api/oauth/usage https://api.anthropic.com/api/oauth/profile The token and quota data never leave your machine. ⚠️ These Anthropic endpoints areundocumentedand may change or break at any time. Claudeometer is an unofficial tool and is not affiliated with Anthropic. The "Hot sessions" list and pace history are derived from your local Claude Code logs in ~/.claude/projects . Claudeometer can also share and pool Claude usage across your teams : create or join teams public or private, with a name and password , see everyone's live usage on a per-team board, and borrow a teammate's Claude quota for a fixed window when you're out. Borrowing is scoped to teams you share, and a lent credential is end-to-end encrypted to the borrower — the relay only ever brokers opaque ciphertext and never sees a token. Team mode talks to a small self-hosted relay relay/ — a Go + SQLite service; see relay/PROTOCOL.md . The relay URL is deliberately not baked into this repo. Point the app at your own relay with either: - an environment variable: CLAUDEOMETER RELAY URL=http://your-relay:8080 , or - a one-line file at ~/Library/Application Support/Claudeometer/relay-url containing the URL. With neither set, Claudeometer stays a personal usage meter — no team prompts, no network. Don't want to host your own relay? Reach out and I'll share mine — connect with me on LinkedIn or email sanketwable123@gmail.com , and I'll send you a hosted relay URL to point the app at. Requirements: macOS 13+ and a recent Swift toolchain Xcode 16+ . chmod +x scripts/build-app.sh ./scripts/build-app.sh open build/Claudeometer.app The app bundle is produced at build/Claudeometer.app .
