Claude 用量与限额 – Claude Code Usage

一眼掌握 claude code usage：会话与每周限额、重置计时器，以及工具栏上的实时量表——无需点击。

Run out of capacity mid-task and your momentum is gone. Claude Code Usage is a lightweight toolbar popup that shows, in one click, exactly how much you have left across the 5-hour session window and the 7-day weekly window — no terminal, no dashboards, no surprises. It reads your real claude code usage straight from your claude.ai account and turns it into a clear picture: a session progress bar, a weekly progress bar, a live gauge on the toolbar icon, and a precise reset countdown. Pin it once and you always know where you stand before a heavy session begins. ⚡ Everything in one popup - Session meter — how much of the 5-hour window you have spent. - Weekly meter — your remaining allowance over the rolling 7-day window. - Reset timer — when the next reset lands, down to the minute. - Extra usage — the overflow meter appears when your plan includes it. - Toolbar gauge — your remaining limit, visible with zero clicks. 🧩 Zero clicks: the icon is the meter You do not even have to open the popup. The toolbar icon itself is a tiny live gauge of the 5-hour window: it fills as you work and slides from soft coral to deep red as you approach a cap, with the exact percentage one hover away. Glance, decide, keep coding. Different models burn your quota at very different rates — Opus is powerful but heavy, Sonnet is faster and lighter, and Haiku is the cheapest of the three. Watching this claude code usage monitor during a heavy Opus run shows the window draining in real time, so you can drop to Sonnet before things stall. If you have ever slammed into the claude code max opus limit mid-refactor, you know exactly why that glance matters. 📊 Stay ahead of every claude code limit 1. Spot claude code usage limits and claude code token limits before they bite. 2. Watch the 5-hour rate limit and the weekly cap fill up in real time. 3. Get a heads-up while you are approaching a limit, not after it stops you. 4. Know when does claude code usage reset, without guessing. 📐 Every cap in one place Several limits apply at the same time, and missing any one of them quietly stalls your work. The popup pulls them into a single view so nothing stays hidden: your claude session limit on the rolling 5-hour window, your weekly limit across a full seven days, and the extra usage balance when your plan has one. Seeing your claude usage limits laid out this clearly means a silent ceiling never catches you halfway through a long refactor. Anyone who has hit a claude rate limit error mid-generation knows the sting of losing momentum at the worst possible moment. A quick look at the color-coded gauge warns you while there is still room to react — pause, switch to a lighter model, or wrap up cleanly before the claude 5 hour limit resets. No terminal, no command line, and no context switch to break your focus. 🔋 Works with your plan ➤ Pro and Max are fully supported, including claude code pro limits and the claude max plan usage limits. ➤ Check your overall claude limits, your pro plan limits and the max token limit without opening settings. ➤ It tracks plan quota rather than claude api cost, so the numbers always match the official usage page. 🛠️ Setup in 60 seconds 1️⃣ Install from the Chrome Web Store. 2️⃣ Sign in to claude.ai in the same browser — no claude setup token to paste, no extra login. 3️⃣ Pin it — your personal claude code usage tracker now lives in the toolbar. 🔒 Private by design Everything stays in your browser. The extension speaks only to Anthropic's own servers to read the numbers it shows, and nothing goes anywhere else. Your data is cached locally on your own machine and is never shared. 🔁 Always up to date The popup refreshes on its own every few minutes, so the numbers you see are current, never a stale snapshot from an hour ago. Hit refresh before a big run, watch the progress bars move while a long job runs, and let the toolbar gauge change color as you climb toward a cap. When a window rolls over, the reset countdown restarts automatically, so you never have to do the math by hand or reload anything. 💡 Why developers keep it pinned - A faster, friendlier alternative to checking ccusage and claude code cli usage in the terminal. - Keep your claude usage and overall claude limits visible at all times — without a single click. - See heavy Opus runs drain the weekly window in real time, and switch to Sonnet in time. - Plan big refactors around the rate limit instead of getting blocked. - Track the session window and the weekly window together, in real time. - Pace context-heavy jobs ahead of a reset, never after it. 👤 Perfect for - Engineers shipping with an AI coding assistant every single day. - Data and ML folks running long jobs that burn through tokens fast. - Teams pacing work across the 5-hour and 7-day windows. - Anyone on Pro or Max who hates being surprised by a cap. ❓ Frequently asked questions Q: Does it show both windows at once?
