Claude Monitor: Session & Weekly Usage Limits από msadofschi

Never get cut off by a Claude usage limit again.

Claude Monitor, a Claude usage tracker, shows how much Claude you have left, live in your toolbar: your 5-hour session limit, your weekly limit, per-model caps like Fable 5, extra usage credits and Claude Code routine runs, each with a countdown to the minute it resets.

Stop hitting "You've reached your usage limit" halfway through a task, and stop refreshing claude.ai/settings/usage. One look at the badge tells you whether to keep going or slow down.

New: your limits right where you type

Turn on the optional usage bar and your session and weekly limits sit right above claude.ai's chat box, so you see them while you write. It follows Claude's light or dark theme and stays out of your way.

New: works on the Free plan

Claude closed its usage page to Free accounts, but every reply still carries your limits, and with the bar on, this extension reads them each time you send a message. Free, Pro, Max, Team and Enterprise are all covered.

New: in your language

The popup, settings, alerts and the on-page bar are available in English, Spanish, Portuguese (Brazil), German, French, Italian, Japanese and Korean. It follows your browser's language, with dates and amounts in your local format.

What you get

• Live session (5-hour) and weekly usage, color-coded green, yellow and red
• A countdown to every reset, down to the minute
• Per-model weekly caps, shown only for the caps your plan actually has, so you never see a phantom 0%
• Desktop alerts at 80% and 95%, or at your own thresholds, once per reset window
• Extra usage credits in real money: spent vs. monthly limit, prepaid balance and reset date
• Claude Code daily routine runs (used / limit)
• A trend line under every bar and up to 30 days of history, with export to CSV or JSON
• A clear warning when data goes stale, so an old number never passes for a live one
• Six color themes and four popup layouts
• Your plan as a badge: Free, Pro, Max 5x, Max 20x, Team

Private by design

• No account, no API key, no sign-up: it uses the claude.ai login you already have
• Your usage data stays in your browser. No analytics, no telemetry, no tracking. The extension only talks to claude.ai, with read-only requests
• Read-only: it never changes your account or spends your usage
• It never stores or sends your prompts, Claude's replies, projects or files. With the optional bar on, it scans each reply only for the usage figures Claude attaches to it
• If you uninstall it, an optional one-question survey opens on claude-monitor.com. Its address carries only the extension version and browser name; if you answer, the survey stores your answer with those, the time and your country
• Open source (MIT) and unminified, so anyone can check every line on GitHub

Permissions, and why

• Storage and alarms: keep your data and refresh it on schedule
• Notifications (optional): the 80% and 95% alerts
• claude.ai: the extension's code only sends read-only requests, to five endpoints: /api/organizations, /api/organizations/*/usage, /api/organizations/*/prepaid/credits, /api/organizations/*/overage_spend_limit, /v1/code/routines/run-budget
• claude.ai pages and scripting (optional, only if you turn on the bar): draw the bar and read the usage figures from each reply

FAQ

Does it track Claude Code usage?
Yes. Claude Code on a Pro or Max plan draws from the same session and weekly limits, so the usage you burn in the terminal shows up here too, along with your daily routine runs.

Does it work on the Free plan?
Yes, with the usage bar turned on in Settings. Your limits appear after your next message.

Can it see my conversations?
It never stores or sends your prompts, Claude's replies, projects or files. With the optional bar off, it doesn't run on claude.ai pages; with it on, a script passes over each response stream and extracts only the usage figures, without decoding anything else.

Is it free?
Yes, free and without ads.

Also on Windows

UsagePeek AI keeps your Claude limits next to the clock even with the browser closed, and reopens your Claude Code projects the moment a limit resets. Free 7-day trial.
