Claude Usage Monitor

What it does

A free, open-source browser extension that puts your Claude limits in your toolbar: 5-hour session, weekly all-models pool, per-model caps (Opus, Sonnet, Design), routine runs and extra credits, all with live reset countdowns. Local-only, reads no chats. Chrome and Firefox.

Never hit your Claude limits unexpectedly. Track your 5-hour session, weekly limit, and per-model caps for Fable, Opus & Sonnet in real time — with desktop alerts at 80% and 95%.

A color-coded badge in your toolbar shows your live session and weekly usage, and desktop alerts warn you at 80% and 95%. One click opens the rest: per-model caps like Fable's new weekly cap, routine runs, and your detected plan. A desktop extension for Chrome and Firefox — open this page on your computer to install. Scroll down to try the live demo. Go ahead, try it — toggle metrics, switch themes, change the layout, hit refresh. It's the real popup, not a screenshot. On pay-as-you-go, the top banner tracks your monthly extra-usage spend and remaining prepaid balance, with a live percentage bar, real currency symbols (€/£/$) and a reset countdown. Your rolling 5-hour window,…from claude-monitor.com

  I kept hitting Claude's 5-hour limit without realizing it, so I made this menu bar app to track it. Shows a color-coded ring (green/orange/red) and countdown to reset. Built it in Swift/SwiftUI, just for myself initially. Right now you have to manually grab your sessionKey from browser DevTools, which is annoying but works. Stores it in macOS Keychain so it's secure. Been actively working on it, already at v1.3.0 with much better UX now. It's open source (MIT) and works with all Claude platforms (web/CLI/desktop/mobile) since they share the quota. Currently…

  Claude Code Usage Monitor – real-time tracker to dodge usage cut-offs2025 · github.com · ▲245

  I kept slamming into Claude Code limits mid-session and couldn’t find a quick way to see how close I was getting, so I hacked together a tiny local tracker. Streams your prompt + completion usage in real time Predicts whether you’ll hit the cap before the session ends Runs 100 % locally (no auth, no server) Presets for Pro, Max × 5, Max × 20 — tweak a JSON if your plan’s different GitHub: https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor It’s already spared me a few “why did my run just stop?” moments, but it’s still rough around the edges. Feedback, bug…

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
