Chrome extension
A color-coded badge in your Chrome toolbar, updating while you browse. Free, no account. On Microsoft Edge, install it from the Edge Add-ons listing; everything below works the same.
Install it
Open the Chrome Web Store listing and click Add to Chrome.
Click the puzzle-piece icon in the toolbar and pin Claude Monitor so the badge stays visible.
Make sure you're signed in to claude.ai in the same browser; that's the only "login" it needs.
How to use it
The toolbar badge shows your live session percentage, colored by how close you are to the limit. Click it to open the popup with the full picture: your 5-hour session, weekly usage across all models, per-model caps (Fable, Opus, Sonnet and Claude Design when your plan has them), usage credits and daily routine runs, each with its exact reset time. Choose from several layouts and themes in the popup. Desktop alerts at 80% and 95% are optional: click Turn on in the popup's "Get alerts" notice, or tick alerts in Settings, and allow notifications when the browser asks. With alerts on, it also tells you when a session that crossed the warning threshold resets.
See your limits above the chat box
The optional usage bar shows your session and weekly limits right above claude.ai's chat box, in chats, projects and Claude Code. The quickest way to turn it on is the welcome page that opens when you install the extension: click Show my limits inside Claude. Later, open Settings from the popup and tick Show a usage bar above the chat box, and allow access if the browser asks. It's off by default, and you can turn it off again in Settings at any time.
On the Free plan
Since August 2026 claude.ai shows no usage to Free accounts, so the popup has no numbers to show until the bar is on. Turn it on (the popup's Free plan notice has a Turn on button that does the same), then send any message on claude.ai: your limits arrive with Claude's reply, and the badge, popup and alerts update after each message. More in the Free plan guide.
Firefox add-on
The same monitor, the same popup, for Firefox. Free, no account.
Install it
Open the Firefox Add-ons listing and click Add to Firefox, then Add to confirm.
The icon appears in your toolbar. If it's tucked away, open the extensions menu and pin it so the badge shows.
Make sure you're signed in to claude.ai in the same browser.
How to use it
It works exactly like the Chrome version: a color-coded badge shows your live session percentage, and one click opens the popup with your session, weekly and per-model caps, credits and routine runs, each with its reset time, plus layouts and themes. The usage bar, the Free plan reading and the optional desktop alerts at 80% and 95% work the same way too.
Windows app: UsagePeek AI
A native app that lives in your system tray and polls your usage on its own, so your limits stay current even with every browser closed. It can also resume your Claude Code projects when your session limit resets. More about it on the UsagePeek AI page. Full site: usagepeek.com.
Install it
Open the Microsoft Store listing and click Get. It's a 7-day free trial, then a one-time purchase, no subscription.
It installs in one click and adds itself to your tray, and updates arrive through the Store automatically.
Sign in once
The app reads your usage through your own Claude login:
The first time it runs, the app opens a Log in to Claude window with the claude.ai sign-in page.
Sign in the way you always do, with Google or email.
The window closes on its own, and the tray icon starts showing your session percentage.
Closed that window before signing in? Right-click the tray icon and choose Log in to Claude.
What you'll see
The tray icon shows your session percentage, colored by how close you are to the limit:
Click the icon for the full popup: Current Session (the 5-hour window) and Weekly · all models, each with its reset time. When your plan reports them, it also shows the per-model caps (Fable weekly, Opus weekly, Sonnet weekly, Claude Design), which the app shows with the weekly reset time, plus Daily routine runs and Credits. Make it yours with 4 layouts, 6 themes and a floating widget you can drop anywhere on screen and keep above other windows. Two global keyboard shortcuts work anywhere in Windows: Ctrl+Shift+U shows or hides the widget and Ctrl+Shift+M changes its design (both can be changed in Settings).
Usage alerts
Get a heads-up before you hit a limit. The app sends a Windows notification when a limit crosses a threshold: a warning at 80% and a critical alert at 95% by default. Out of the box it watches Current Session and Weekly · all models; you can add the per-model caps under Alert on. Each threshold fires once and can fire again only after that usage drops back below it. In Settings → Alerts you can change Warn at % and Critical at %, or untick Enabled to turn alerts off.
Auto-resume Claude Code
The standout feature. Queue up your Claude Code projects and, when your 5-hour session window resets, the app resumes each one you armed, in a terminal or in the Claude desktop app. This part assumes you already use Claude Code.
claude command, so you need Claude Code installed first: follow the official Claude Code install guide.
claude in a folder, it asks you to sign in with your Anthropic account and to trust the folder. Accept that once per project. You accept those prompts yourself; the app only relaunches Claude Code.
Open Claude Code manually (once)
Before queuing a project, make sure it runs on its own: open a terminal (Windows Terminal or PowerShell) in the project folder and type claude. Complete the sign-in and folder-trust prompts if they appear. Once it launches cleanly, it's ready to queue.
Build the queue
Click the tray icon, open Settings (the ⚙ button) and expand Auto-resume.
Click + Add project and pick your project from the list of Claude Code projects on this PC, or choose Browse for a folder… and select the folder you launch Claude Code from.
Choose a session: Latest session, or a specific one from the list.
On the new entry, choose where it resumes: Desktop app (the default) or Terminal. Keep its checkbox ticked to arm it. An entry fires once; the ⟳ button makes it repeat on every reset, and ▶ launches it right away.
When the session limit resets, the armed entries launch in queue order. Each Terminal entry opens its own terminal window running claude --resume (or claude --continue for Latest session) with the entry's prompt.
If it shows nothing or stops updating
For the Chrome, Firefox and Edge extensions. Try these in order; the first one fixes most cases.
Sign in to claude.ai again. The extension reads your usage through your claude.ai login. When that session expires, the badge turns gray or the popup says Signed out: data is stale, and the extension waits longer and longer between retries. Open claude.ai in the same browser, sign in, then open the popup and click the refresh button (the circular arrow): a manual refresh skips the wait.
Check that the extension is turned on. Browsers sometimes switch an extension off, for example after an update. Open
chrome://extensions(edge://extensionsin Edge,about:addonsin Firefox), find Claude Monitor and make sure its toggle is on.Reinstall it. If it is still stuck, turn it off and on again, or remove it and add it back from the store. Your limits come from your Claude account, so they return on the first refresh; if you remove it, only the local history and your settings start over.
Still not working? Email [email protected] and tell us your browser and what the popup shows (a gray badge, a "?", an error or old numbers).
Good to know
It's private, everywhere
In the extension, your usage data stays in your browser: no account, no analytics, no telemetry. It never stores or sends your prompts, replies, projects or files. The Windows app has its own privacy policy at usagepeek.com/privacy.
What you need
A Claude.ai account, and either desktop Chrome, Firefox or Edge, or Windows 10/11. Auto-resume additionally needs Claude Code. WebView2 is built into Windows 11.
