Neon Meter Host

Desktop host app for showing live AI usage on the Neon Meter CoreS3 device. It is the companion app for the SunboX/neon-meter project.

Device

Screenshots

The menu bar quota display is enabled by default and shows remaining Session (S) and Weekly (W) capacity for the active provider. Its gauges use the same remaining-capacity color buckets as the Neon Meter CoreS3 display. You can hide or show the menu bar gauges from the tray context menu; hiding them only removes the status-bar display while provider sync and device updates continue.

Quick Start

npm install
npm start

No credential setup is required in the app. Neon Meter uses credentials already managed by Claude Code or Codex on the local machine.
