What OpenUsage is
OpenUsage tracks how much of your AI subscriptions you have used: Claude, ChatGPT, Cursor, Antigravity, Copilot and Grok sign in with OAuth; Ollama, OpenCode, OpenRouter and Z.ai use API keys. It shows only the limits and dollar values each provider's own API reports, stores tokens in its own Keychain service and updates itself through signed Sparkle updates.
