Brink

Brink

Know when you're on the brink. A tiny panel that lives on the right edge of
your screen and shows your Claude Code, Codex and Cursor usage limits
at a glance — and, on macOS, which project spent them. For macOS and Windows.

Move the mouse to the thin strip on the right edge → the panel slides out.
Hover a ring → a card shows the session limit, weekly limits and reset times.
One line at the bottom answers the follow-up question: *what used it?*

No Dock icon, no menu bar clutter. Just the edge.

Features

- What used it — break the limit down by project, over the current session, the
  week, this month or all time. Built from the transcripts Claude Code already
  writes; reads token counts only, never message content. macOS only for now.
- Three looks: Black, Liquid Glass and System. On macOS 26+ the glass is
  Apple's real, adaptive Liquid Glass (.glassEffect): it turns light or dark from
  what's behind it, so type stays legible over a white web page and a dark wallpaper
  alike. On macOS 13–15 it falls back to a frosted NSVisualEffectView blur.
- Notch-style tab that flares into the screen edge; rings scale on hover; the detail card glides between rings
- Notifications when a limit fills up — and again the moment it resets (scheduled for the reset time, so it arrives even if the app is idle)
- 10 languages — follows your macOS language automatically (English, Türkçe, Deutsch, Français, Español, Português (Brasil), Italiano, 日本語, 简体中文, 한국어); override in the menu
- Rings for each provider, colored by usage (green → yellow → red; Claude ring in Claude orange)
- Detail card with Current session, All models and per-model weekly limits (e.g. Fable / Opus / Sonnet)
- Auto-refresh every 2 minutes, manual refresh from the context menu
- Launch at login toggle (System…
