Track your AI token burn. In real time.

Custom metrics turn System Gauge into a live dashboard for your coding agent spend. Point a widget at a local URL and watch the numbers update on your desktop.

  • Monitor token usage across LLM APIs

    Track consumption across Claude, GPT, Gemini, and any other API. See your burn rate right on your desktop.

  • Track spend and rate limits

    Stay ahead of budget overruns. Glanceable cost tracking without switching to a billing dashboard.

  • Powered by a simple local web server

    Custom metrics read from a URL you provide — run a lightweight local server that exposes your stats, and System Gauge handles the rest. Any data source that can serve a number works.

  • Built for developers using AI coding agents

    Cursor, Claude Code, GitHub Copilot — if it burns tokens, System Gauge can track it.

Frequently asked questions

What metrics does System Gauge monitor?

System Gauge monitors CPU usage, memory pressure, network throughput (upload and download), disk space, battery level, thermal pressure, and process count. You can also add custom metrics to track anything else, like AI token usage or API costs.

Does it support custom metrics?

Yes. Custom metrics fetch data from a URL you configure — typically a lightweight local web server that exposes your stats as a number. System Gauge polls the URL and displays the value in a desktop widget alongside your built-in system metrics. Developers use this to track AI coding agent token usage, API costs, CI pipeline status, and more.

Can I monitor AI token usage with System Gauge?

Yes. Set up a simple local web server that exposes your token counts or API spend as a number, then point a custom metric at its URL. System Gauge will display it in a desktop widget that updates automatically. Works with Claude, GPT, Gemini, and any other LLM API — perfect for developers running AI coding agents like Cursor, Claude Code, or GitHub Copilot.

How do I customize the widgets?

Open System Gauge settings and go to the Widgets tab. Choose small, medium, or large widget sizes. Click any slot to change the metric, and drag slots to reorder. Changes appear on your desktop within seconds.

Does it use a lot of battery or CPU?

No. System Gauge is built with native SwiftUI and WidgetKit. It uses minimal CPU and has negligible impact on battery life. Widgets update efficiently through the system's built-in widget scheduling.

What version of macOS do I need?

System Gauge requires macOS 15 (Sequoia) or later.

How much does System Gauge cost?

System Gauge is a one-time purchase of $4.99 on the Mac App Store. There is no subscription and no additional in-app purchases. All future updates are included.
