QuotaMeter is a Chrome extension designed for tracking AI service usage limits and API costs in a unified dashboard. This free tool helps users, particularly developers and AI enthusiasts, to monitor their subscription quotas and spending efficiently. It supports a variety of services including Cursor, Claude, Codex, GitHub Copilot, and Google Gemini, offering detailed insights into usage limits and billing cycles. The clean interface features color-coded progress bars for easy visualization of remaining quotas.

Key features include smart notifications that alert users before reaching their limits, ensuring proactive management of quotas. The extension automatically refreshes data every 15 minutes, optimizing resource use during idle periods. For added convenience, a macOS menu bar app is available, which allows users to check their quotas without opening Chrome. Privacy is prioritized as all data remains local, with encryption for sensitive information.
