claudometer 1.1.0

Live Claude usage limits (session & weekly) on your taskbar / menu bar — so you never hit a limit by surprise.

Claudometer

Your Claude usage limits, always visible — right on your taskbar.
A tiny desktop widget that shows your live session & weekly usage, so you never hit a limit by surprise.

Why

Claude's Pro / Max / Team plans enforce a rolling 5‑hour session limit and weekly limits. Use Claude Code heavily and it's easy to burn through them mid‑task — then get rate‑limited at the worst moment. Checking today means opening the /usage panel and remembering to look.

Claudometer keeps that number on‑screen all the time, as clean floating text that sits on your taskbar by default — sampling its color so it blends right in:

🖱️ Put it anywhere

The strip is a free‑floating, always‑on‑top widget — not locked to the taskbar. Drag it to a screen edge, over a window, or onto a second monitor, and it remembers the spot. (On macOS the native menu‑bar item is the default; the same floating widget is available with app.py bar — see Platform support.)

• Session 61% — your current 5‑hour window, with a live countdown to reset.
• Weekly 18% — your 7‑day, all‑models usage.
• A color dot (🟢 <50% · 🟡 50–80% · 🔴 >80%) that flips to a clear "limit reached" when you're maxed out, plus a graceful offline state:

Click it for the full breakdown — per‑meter reset times, per‑model usage, light/dark:

What you get

• 🎯 Pace yourself — spot a limit before you hit it.
• ⚡ Zero context‑switch — the number's already there; no panel to open.
• 🔒 Zero setup — reuses your existing Claude login. Nothing to configure.
• 🪶 Featherweight — ~0.03% CPU idle, ~50 MB RAM. You won't notice it.
• 🔔 Alerts — optional desktop toast when you cross 80% / 90%.
• ⏭️ Resume — one click picks up interrupted work when your limit resets (auto‑resume optional).
• 🖥️ Out of the way — auto‑hides over fullscreen movies/games (or set it to always show).
• ⚙️ Tunable — a built‑in settings panel (no file editing) for theme, meters, alerts, accent, cost view, and more.

Threshold alerts — a desktop toast the moment you cross a limit you set:

Estimated cost (opt‑in) — today's tokens + a rough dollar figure in the popover (a local estimate, not a bill):

Always‑visible mode — keep it readable even over a fullscreen movie or game:

Install

Requires a Claude Pro / Max / Team subscription, signed into Claude Code at least once (that's where the login lives).

Easiest — one command, any OS:

pipx install claudometer      # no pipx?  →  python -m pip install --user pipx
claudometer

Update later with pipx upgrade claudometer.

Windows:

scoop install https://raw.githubusercontent.com/ali-dev178/claudometer/main/packaging/scoop/claudometer.json

…or download the installer (ClaudometerSetup.exe, offers "start on sign‑in") or the portable Claudometer.exe from Releases.

macOS:

brew install --cask ali-dev178/claudometer/claudometer

…or download Claudometer.dmg from Releases and drag it to Applications.

From source (Python 3.9+):

git clone https://github.com/ali-dev178/claudometer.git && cd claudometer
pip install -r requirements.txt
pythonw.exe app.py bar    # Windows (no console)   ·   python3 app.py   # macOS

Unsigned downloads: on first launch, Windows ("More info → Run anyway") or macOS (right‑click → Open) may ask you to confirm. Installing via pipx / scoop / brew skips that.

Windows 11 tip: new taskbar items can get tucked away — drag Claudometer where you want it; it remembers the spot.

Resume when your limit resets

Hit the session limit mid‑task and everything stalls? Claudometer watches your usage recover and helps you pick right back up.

• Tier 1 — notify + one click (default, safe). On reset, a notification appears; click Resume to open a terminal in the interrupted session's folder running claude --resume — you stay in control.
• Tier 2 — auto‑resume (opt‑in, off by default). After a "resuming in 20s — click to cancel" window, it resumes unattended so work continues while you're away.

⚠️ Tier 2 runs Claude Code with nobody watching. It's off unless you set resume_auto = true, and it's guard‑railed: a turn cap plus the safer acceptEdits mode by default (full --dangerously-skip-permissions only if you also opt in). Enable it only for work you trust to run on its own.

Configure

In‑app (recommended): click ⚙ Settings in the popover (or right‑click the strip → Settings…). Adjust theme, meters, accent, poll interval, alerts, cost view, fullscreen behavior, and resume — changes apply instantly and save to ~/.claudometer.toml for you.

Or edit the file by hand — copy claudometer.example.toml to ~/.claudometer.toml:

poll = 90                        # seconds between polls (60–300)
theme = "auto"                   # auto | light | dark
metrics = ["session", "weekly"]  # which meters on the strip
hide_on_fullscreen = true        # false = stay visible, even over fullscreen apps
alerts = true                    # desktop toast on threshold crossings
alert_thresholds = [80, 90]
show_cost = false                # estimated token/$ line in the popover
# accent = "#d97757"             # override the accent color

resume_notify = true             # one-click resume when the session limit resets
resume_auto = false              # Tier 2: unattended auto-resume (opt-in, risky)
resume_prompt = "Continue where you left off."
resume_max_turns = 30            # Tier 2: cap agentic turns
# resume_skip_permissions = false  # Tier 2: --dangerously-skip-permissions (else acceptEdits)

Optional environment overrides:

Env var	Purpose
CLAUDOMETER_CONFIG	Path to the config file (default ~/.claudometer.toml).
CLAUDE_CONFIG_DIR	Where to read Claude credentials (default ~/.claude).
CLAUDE_WIDGET_POLL	Poll interval in seconds (60–300), for the tray/menu‑bar.
CLAUDE_WIDGET_FAKE	Testing: "95,40,0" = session,weekly,scoped % (skips the network). Try $env:CLAUDE_WIDGET_FAKE="95,40,0"; py app.py bar to preview the red state.

On macOS / Linux the default menu‑bar / tray shows live usage; the full feature set (alerts, cost, resume, themes, settings panel) runs in the floating widget — app.py bar (see Platform support).

Run modes: app.py bar (Windows taskbar strip — default & recommended) · app.py tray (tray icon) · app.py both · app.py (auto per platform). Strip: left‑click = popover · drag = move it anywhere on screen (remembered) · right‑click = menu.

▶ Try a demo

Want to see every feature without waiting to hit a real limit? Click Settings → ▶ Try a demo (or right‑click the strip → Try a demo, or run app.py demo). Your widget switches in place (one window, not a second) into a ~50‑second offline tour covering every state — all clearly badged DEMO:

• the color dot cycling green → amber → red
• session and weekly threshold alerts (80% / 90%)
• the limit‑reached and rate‑limited states
• resume‑on‑reset — both Tier 1 (notify + one click) and Tier 2 (auto‑resume countdown)
• the estimated cost line (click the strip to see it) and the graceful offline state

Pick ◼ Exit demo to snap back to your real usage. No network, no credentials, nothing real touched.

Auto‑start on login: the Windows installer can set this up for you. Manual (from source) — Windows: add a shortcut to pythonw.exe "…\app.py" bar in shell:startup. macOS: add the standalone Claudometer.app to System Settings → Login Items, or use a LaunchAgent for a source install:

macOS LaunchAgent (source install)

~/Library/LaunchAgents/com.claudometer.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0"><dict>
  <key>Label</key><string>com.claudometer</string>
  <key>ProgramArguments</key>
  <array><string>/usr/bin/python3</string><string>/absolute/path/to/claudometer/app.py</string></array>
  <key>RunAtLoad</key><true/>
</dict></plist>

Then: launchctl load ~/Library/LaunchAgents/com.claudometer.plist

How it works

Claudometer reads the OAuth token Claude Code already stores locally (~/.claude/.credentials.json, or the macOS Keychain) and polls Anthropic's server‑reported usage endpoint — the same source the /usage panel uses:

GET https://api.anthropic.com/api/oauth/usage

So it shows true plan % from Anthropic's backend — not a local token‑cost guess (unlike tools that tally *.jsonl transcripts). Tokens refresh automatically when they expire.

• Privacy — your token is read locally; the only network call is the authenticated request to api.anthropic.com. No third‑party servers, no telemetry, no analytics.
• Footprint — ~0.03% CPU idle, ~50 MB RAM. The strip only redraws when a value changes; the popover only while it's open.

Platform support

Platform	UI	Status
Windows 10/11	Taskbar strip + click‑to‑open popover — full feature set	✅ Full
macOS	Menu‑bar item (default) or the full floating widget via app.py bar	✅ Full
Linux	Tray icon (default) or the floating widget via app.py bar	🧪 Experimental

The floating widget is one cross‑platform codebase — the same strip, drag, popover, alerts, resume, settings panel, cost and demo run on every OS. On macOS the default is the native menu bar; python3 app.py bar gives you the full floating widget.

Roadmap

Shipped: desktop alerts · config file + in‑app settings panel · estimated‑cost view · standalone binaries + release CI · pipx / Scoop / Homebrew installs · cross‑platform floating widget (macOS/Linux).

Next: usage sparkline over the session · per‑model cost breakdown · published winget listing.

Ideas and PRs welcome — open an issue.

Contributing

pip install -r requirements.txt && py app.py bar   # run it
pip install -r requirements-dev.txt && pytest        # run the tests (also in CI)

usage_core.py = data/auth (no UI deps) · render.py = all the Pillow drawing · settings.py / cost.py / resume.py = config, cost estimation, session‑resume · the platform adapters (widget_bar.py, menubar_mac.py, tray_windows.py) are thin. The tests/ suite (~385 checks on the core logic) runs on every push via CI; regenerate the README images with py assets/make_assets.py.
