About TokenTelemetry
TokenTelemetry is an open-source developer tool designed to give you deep visibility into what your AI coding agents think, cost, and do. Instead of requiring complex setups, TokenTelemetry works by reading the session logs that your AI coding agents already write directly to your disk, transforming them into a comprehensive local dashboard.
With support for 13+ popular agents—including Claude Code, Codex, Cursor, Copilot, Gemini CLI, Antigravity, Grok, OpenCode, Cline, Qwen, Pi, and Hermes—the tool tracks crucial metrics such as token usage, cost accumulation, step-by-step trace replays, subagents, skills, and Model Context Protocol (MCP) calls.
Built with developer privacy and simplicity in mind, TokenTelemetry requires no SDK, no code changes, and no cloud account. It can be installed with a single command, keeping all of your data entirely secure and local on your machine.
Pros of TokenTelemetry
- Supports 13+ popular AI coding agents out of the box (Claude Code, Cursor, Copilot, Cline, etc.)
- Requires zero SDK integrations, code modifications, or cloud accounts
- Complete local-first architecture ensures all session data stays on your machine
- Provides granular insights including token consumption, costs, and step-by-step trace replays
- Open-source developer tool with a simple one-command installation
Cons of TokenTelemetry
- Relies entirely on existing session logs written to disk by the supported AI agents
- Limited to local dashboards without native cloud-sharing or team synchronization features mentioned
