Windows system tray app that tracks usage limits and spend for Claude, Codex, Cursor, Copilot, and other AI coding tools.

AIUsage.NET is a free, open source .NET 8 / WPF port of OpenUsage for Windows. It sits in the system tray and shows session and weekly limits, credits, and local spend estimates for AI coding subscriptions (Claude, Codex, Cursor, Copilot, Antigravity, Devin, Grok, OpenCode, OpenRouter, Z.ai), reading credentials already stored on the machine. Includes a local command-line tool and a read-only local HTTP API for scripting and other apps to consume the same usage data.
