simple-usage-monitor is a command-line interface (CLI) tool designed for real-time monitoring of token usage and cost estimates when working with Claude Code, all directly within the terminal. This utility enhances productivity by eliminating the need to switch between various dashboards or web interfaces, allowing users to stay focused on their coding tasks.

Key Features

• Live Usage Data: View current token counts for input, output, and cache as you work.
• Cost Tracking: Monitor expenses associated with token usage, featuring tiered pricing models tailored to your subscription.
• Session Management: Keep track of session limits based on the selected plan to avoid unexpected charges.
• Privacy: All computations are conducted locally, ensuring that usage data remains confidential and secure.

Supported Models

• Opus 4.5
• Sonnet 4.5
• Haiku 4.5

While additional models provide detailed token counting, dollar cost metrics are currently limited to the supported models.

Getting Started

To begin using simple-usage-monitor, simply run the command:

sumonitor
