Open-source Claude/Codex/Cursor limits tracker for Mac (github.com)

A new open-source macOS application, CreditWatcher, has been launched to monitor subscription usage limits for Codex from OpenAI, Claude Code from Anthropic, and Cursor in a streamlined, read-only format. Designed as a lightweight menu bar app using native Swift, it eliminates the need for Node.js during runtime. This tool allows users to keep track of their API usage across three different providers locally, ensuring no telemetry or data is sent externally. Prebuilt installers are available on GitHub, offering easy access for users looking to manage their AI tool utilization effectively. CreditWatcher’s significance lies in its commitment to privacy and user autonomy, providing a secure way to track usage without compromising sensitive credentials. By storing OAuth tokens and session data locally, it minimizes security risks often associated with cloud-connected applications. Key technical features include a 60-second cooldown for refreshing data to avoid overwhelming provider APIs and the ability to visualize usage via a rich terminal interface or a menu bar popover. This tool not only enhances management capabilities for AI/ML developers but also exemplifies local-first software design principles, bridging usability with security.
