Know how much Claude Code, Codex and Cursor you have left — without opening a single usage page.
A free, open-source macOS monitor that sits on the edge of your screen and shows every AI coding limit at a glance.
macOS 14 Sonoma or newer · Apple Silicon & Intel · English · 简体中文 · 繁體中文 · 日本語 · 한국어
- Seventy-six services at a glance — Claude Code, Codex, Cursor, GitHub Copilot, Antigravity, Kiro, Grok, DeepSeek, Kimi Code and many more, each as its own ring.
- No Pulse account, no Pulse server — it uses the logins you already have, and nothing is sent back.
- Real numbers only — every usage percentage is the one the service itself reported. The few estimates are marked as such, and where a service reports nothing, Pulse says so instead of guessing.
- Native and quiet — Swift and SwiftUI, Liquid Glass on macOS 26. Dock it left, right, along the top or along the bottom beside the Dock, let it fold to a sliver when idle, or keep it in the menu bar.
Recently added: usage in the menu bar with a dashboard for each account, starting usage windows after a reset, and animated bot marks. What's new.
If Pulse has saved you from a surprise rate limit, a ⭐ helps other people find it.
- Download the latest
Pulse-x.y.z.dmgfrom Releases. - Open the disk image and drag Pulse into your
Applicationsfolder. - On first launch, choose the services to monitor. All start unchecked; Pulse reads their credentials and checks usage only after you click Done. Closing the chooser leaves monitoring off; you can also enable a service in Settings. Upgrades keep your choices and ask once about newly supported services detected on your Mac.
- Pulse lives in the menu bar. If your menu bar is crowded, right-click the floating rail — or the collapsed sliver — and choose Settings…; you can also assign a global shortcut for it under Settings › General › Shortcuts.
Note
macOS Gatekeeper First Launch:
Pulse is an open-source project without an Apple Developer certificate. On first launch, macOS may block the app:
- Option 1 (GUI): Launch Pulse, dismiss the alert, open System Settings → Privacy & Security, and click Open Anyway.
- Option 2 (Terminal):
Updates are offered in-app through Sparkle. macOS may request browser keychain access again after an update.
xattr -cr /Applications/Pulse.app
- Colours that follow usage — green through amber to red, or a colour of your own for each account.
- Used or left —
75% usedor25% left, with an optional clock arc for how much of the window has passed. - Live activity — a turning dot while an agent is working, and optional animated bots that react to each account.
- Every limit and its reset on one card, in continuous or segmented bars.
- Detailed card — the plan, when it was read, what each limit is worth, and recent usage from this Mac's records.
- Burn-rate forecast — tells you when your pace will run out before the window does.
- In the menu bar — the fullest ring as a figure, a small ring or split limits, with an optional dashboard.
- Any edge — left, right, top, beside the Dock, or anywhere at all; it folds to a sliver when idle.
- Notifications you choose — a limit crossing a line, spent, reset, failing checks, a low balance, a provider outage.
- Six languages — English, Simplified and Traditional Chinese, Japanese, Korean and Russian.
- Optional extras — global shortcuts, following the active display, hiding from screenshots.
- Token spend — what 54 local clients have used, priced at public API rates, by day, model and agent.
- Estimates in your currency — dollars, yuan, Hong Kong or New Taiwan dollars, yen, won or roubles.
- Monthly and yearly recap — shareable cards built from the same records.
- Service status — 44 providers' own status pages, and a notification when one reports an outage.
- Connection diagnostics — where each figure came from, and the servers' own replies.
- For power users — several accounts per provider, extensions for your own sources,
Pulse --jsonfor scripts.
Everything in detail: Docs/features.md.
76 services, each read the way the product itself works — its own usage endpoint, the editor's login, a local language server, or a key you paste — and every percentage is the one the service reported. The full list, and how each is read.
- No Pulse account, no Pulse server — your Mac talks to the services you use, under your own logins.
- Five kinds of connection, all listed — those services, their public status pages, models.dev for model prices, ExchangeRate-API only when you pick a currency other than the dollar, and GitHub/Sparkle for updates.
- Your keys stay on your Mac, encrypted, and the usage records Pulse reads never leave it.
Pulse is built with native Swift and SwiftUI. Building the current sources needs the full Xcode (not the Command Line Tools), including the macOS 26 SDK; the app runs on macOS 14+.

open build.noindex/Pulse.appswift run Pulse is a quick way to build and run without a bundle, but notifications and in-app updates only work from the bundled app. See Docs/build-from-source.md for toolchain setup. Shipping a release: Docs/releasing.md.

Pulse was inspired by a UI concept shared by Vinz (@hivinz_) on X in August 2026. Pulse is an independent implementation with its own interactions, functionality, animations, and visual details. Vinz is not affiliated with or responsible for Pulse.
Pulse is free and open source, built in spare time.
If it saved you from a surprise rate limit, you can buy the author a coffee — every cup keeps the rings spinning.
