About Claude Code usage tracking by LangWatch
Claude Code usage tracking by LangWatch is a specialized developer tool designed to give you complete visibility into what your Claude Code sessions actually cost. Built for AI engineers and developers leveraging terminal-based AI coding workflows, this tool provides granular insights into token usage, caching efficiency, and session executions.
Getting started is frictionless—you simply need to run npx langwatch claude once. From there, the tool automatically tracks every session, breaking down costs with cache reads and writes as separate token classes. It logs every bash and Model Context Protocol (MCP) call as an individual span, compares theoretical usage versus billed usage for your Max plan, and delivers a full terminal replay directly in the user interface. Additionally, it offers support for Codex.
Pros of Claude Code usage tracking by LangWatch
- Extremely easy setup with a single command (`npx langwatch claude`)
- Detailed cost breakdown including cache reads and writes as separate token classes
- Tracks every bash and MCP call as individual spans
- Provides a full terminal replay in the UI and supports Codex as well
Cons of Claude Code usage tracking by LangWatch
- Requires integration with LangWatch for tracking and UI visualization
- Focused primarily on terminal-based coding assistant workflows like Claude Code and Codex

About Vizhi
Vizhi (derived from the Tamil word for "eye") acts as a specialized mission control dashboard for monitoring and managing your Codex CLI sessions. Developed by indie developer Ravi Shankar, Vizhi is designed to keep an eye on active execution sessions so developers don't have to constantly tab back and forth into their terminal windows.
The tool provides deep integration with hardware controllers like the Logitech MX Creative Keypad, enabling users to keep track of up to six live sessions simultaneously. Through this physical interface, developers can perform quick action executions, such as one-press session approvals, and issue local voice prompts powered by Whisper.
For developers who do not own a hardware keypad, Vizhi provides a local browser dashboard that offers visibility and control over active sessions. As an open-source developer tool available on GitHub, Vizhi fits seamlessly into terminal-centric AI development workflows.
Pros of Vizhi
- Monitors up to six live Codex CLI sessions simultaneously
- Integrates with Logitech MX Creative Keypad for tactile, one-press approvals
- Supports local Whisper voice prompts for easy command input
- Offers a local browser dashboard for users without a physical keypad
- Open-source developer tool available on GitHub
Cons of Vizhi
- Full physical experience requires a specific device (Logitech MX Creative Keypad)
- Designed specifically around Codex CLI workflows rather than general terminal tasks
