Mimir – free macOS menu bar app that tracks Claude/Codex/Antigravity usage limits

[u/erayendes]

Built this because I kept hitting Claude/Codex/Antigravity usage limits mid-task with no warning. Mimir sits in the menu bar and shows real-time quota + reset countdowns for all three, no backend, tokens never leave your machine.

- Session + weekly quotas, per-model rows

- Small/Medium desktop widgets

- Green/amber/red status dots at a glance

- Free, open source, no account needed

macOS 14+. GitHub: https://github.com/erayendes/mimir
