QuotaLantern

QuotaLantern sits in the system tray and shows how much of the fullest window you have used across Codex, Claude, Gemini and other providers. The icon's ring follows a single recent, named window — never a total or an average — and every state has its own shape: stale readings are dashed with a clock and missing ones are dotted, instead of showing 0%.

The overview has one card per provider, with a bar for each window, the next reset, where the data came from and how old the reading is. API costs are shown in currency and never feed the ring. There is no telemetry: each adapter reads its credential where the provider already keeps it, and the installer copies none. Inspired by Peter Steinberger's CodexBar.
