As developer workflows consume multiple AI subscriptions and API tokens across Anthropic, OpenAI, Cursor, and xAI, tracking remaining quotas and weekly reset cycles becomes a chaotic chore.
The open-source OpenUsage menu bar utility provides a lightweight, zero-cloud architecture for aggregating multi-provider quota telemetry in real-time.
1. Reverse-Engineering Quota Telemetry Safely
- Zero-Credential Storage: Reads session cookies directly from secure local macOS Keychains without transmitting keys to external servers.
- Dynamic Reset Projections: Accurately predicts token replenishment intervals to help developers pace high-throughput batch jobs.
