OpenUsage

OpenUsage is an open-source AI usage tracker that monitors AI coding subscription metrics directly from a macOS menu bar to prevent unexpected service limits.

OpenUsage is a native macOS application that tracks usage metrics for AI coding subscriptions. It provides visibility into token limits and subscription costs by displaying data directly in the menu bar. Users can track multiple accounts for services like Claude, Codex, Cursor, Devin, and Grok alongside other providers. The application functions by reading existing credentials on the machine and syncing history via iCloud. It includes a local API and CLI to integrate status data into editors or agents without requiring authentication tokens. It is built with Swift and SwiftUI and operates as an open-source utility.
