A fuel gauge for all your AI coding subscriptions

What it does Pulse is a free, open-source native macOS app (Swift/SwiftUI) that docks a thin rail of rings against any screen edge — or sits in the menu bar. Each ring is one AI coding service: Claude Code, Codex, Cursor, Copilot, Grok, Kimi, DeepSeek, and roughly seventy others. Hover a ring and a card breaks down every quota pool, reset countdown, and window status. It runs on your existing provider logins — no Pulse account, no Pulse server, nothing sent home.

The interesting bit The honesty discipline is the standout: every percentage is the number the provider itself reported, the few estimates are labeled as estimates, and where a service reports nothing, Pulse says so instead of inventing a figure. That’s rarer than it should be in this category. There’s also an optional local ledger (“Token Spend”) that scans logs and databases from 54 client sources on your Mac and prices your tokens at published API rates — subscription charges excluded, unknown prices left blank rather than guessed.

Key highlights

• 77 providers as rings, with multiple accounts per provider and custom labels
• Optional burn-rate forecast with an estimated time-to-exhaustion when your pace won’t outlast the window (off by default)
• A --json flag prints the last readings from cache, so tmux/sketchybar/shell polling costs nothing
• Auto-collapses to a sliver when idle; opt-in notifications at 75/80/90/95% and on resets
• Extensions let your own program feed one account’s usage in as a ring, no fork required

Caveats

• macOS 14 Sonoma or newer only; no Linux or Windows story
• “Start usage windows after a reset” sends a single “hi” through the provider’s own CLI to start the clock — the README itself warns this may be treated as getting around usage limits
• Token Spend depends on local records; Cursor and Trae need a prior export, and coverage varies by source

Verdict If you juggle several AI coding subscriptions on a Mac and have ever been blindsided by a rate limit mid-task, this earns its spot on your screen edge. Single-tool users and other platforms can skip it.
