OpenUsage
The only AI usage tracker that's truly yours
Overview
OpenUsage is a free, open-source macOS menu bar app that consolidates usage and spend tracking across your AI coding tools in one place. Monitor remaining quota for Claude, Codex, Cursor, Copilot, Devin, Grok, OpenRouter, Z.ai and Antigravity without opening nine separate dashboards, with session, weekly and monthly metrics and alerts before you hit a limit. Built natively in Swift and SwiftUI, with a plugin architecture for adding providers and a local API at localhost:6736 for wiring usage data into your own tools.
