I built Pulse because I run Claude, Codex, Grok and Antigravity (I know) and wanted to see every limit at a glance, without a menu bar or /usage. Always there but I can toss it around the screen when I need to.

What it does:

  • A small rail of rings at the edge of your screen, one per account. The outer ring is usually the 5-hour session, the inner the weekly limit and the center disc for limits like Fable and Argon. Hover for percentages, click for full details and reset times.

  • An alert you can't miss at 98%, 99% and 100%, and a forecast line when your pace would hit a limit before it resets.

  • A Codex pet you can chat with by text or live voice, using your own Codex CLI.

  • Battery alerts, and break reminders with a full-screen break screen.

It runs on your own subscription sign-ins: no API keys, no accounts with Pulse, no backend of its own. Free and MIT-licensed, signed and notarized, with updates through Sparkle. macOS 26 or later, Apple silicon.
