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
Frequently Asked Questions
How do I start tracking my Claude Code sessions?
You can start tracking your sessions instantly by running the command `npx langwatch claude` once.
What metrics and data points does LangWatch capture?
It tracks session costs, cache reads and writes as separate token classes, theoretical vs billed usage for your Max plan, individual spans for bash and MCP calls, and provides a full terminal replay in the UI.
Does this tool work with platforms other than Claude Code?
Yes, the tracking functionality also works for Codex.
About BDFL - Benevolent Delegator for LLMs
BDFL (Benevolent Delegator for LLMs) is an open-source terminal supervisor designed to orchestrate complex coding sessions using AI agents like Codex, Claude Code, and Ollama. Instead of relying on a single AI window, BDFL separates the workflow into specialized roles. Users interact with a 'planning agent' to create versioned, deliberate plans. Once the human user approves the plan—or specific sections of it—BDFL automatically delegates the tasks to isolated 'worker agents' that execute the code in parallel. Beyond just task delegation, the platform handles the heavy lifting of scheduling, running checks, verifying code, and managing integration. Every worker operates in an isolated environment, ensuring that code changes are properly sandboxed and reviewed before being merged. Because it operates entirely locally without any telemetry or centralized tracking, BDFL offers developers a secure, deterministic, and highly observable way to scale their AI-assisted software development.
Pros of BDFL - Benevolent Delegator for LLMs
- Orchestrates multiple AI agents (Codex, Claude Code, Ollama) and allows parallel execution of tasks within isolated worktrees.
- Supports deliberate planning with versioned plans and individual section approvals to ensure tight human oversight.
- Operates entirely locally with no telemetry, keeping runtime state, plans, and source code completely private.
Cons of BDFL - Benevolent Delegator for LLMs
- Currently limited to macOS and Linux environments, with Windows support only listed as planned.
- Requires a highly technical setup, including Node.js 20+, Git, and comfort with advanced CLI workflows.
Frequently Asked Questions
What AI models and agents does BDFL support?
BDFL supports Codex, Claude Code, and local open-source models via Ollama. You can even mix and match models, using one for the planning role and another for the execution workers.
Is my code or data sent to a centralized BDFL server?
No. BDFL operates completely locally and does not collect or publish telemetry, analytics, or runtime state. If you use Ollama with a local model, your entire workflow remains entirely on your machine.
