whereToken

Local-first token usage analytics for coding agents.

Track token usage across Claude Code, Kimi Code, Codex, Cursor,
OpenCode, Grok CLI, Trae, and other supported tools.

Modern developers often use several coding agents at once. Each tool stores usage differently, so there is no single place to see where tokens went. whereToken discovers the data those agents already keep, normalizes it, and presents one view in the CLI, a local dashboard, and JSON.

It is designed to operate locally. Feedback and bug reports are welcome.

Features

Unified usage overview

View token usage from every supported coding agent that has data on this machine.

Agent, provider, and model breakdown

See which application issued the request, which provider served the model, and which model was used.

Historical usage

Inspect daily totals, streaks, and cache hit rate.

Local dashboard

Explore the same data in a browser interface that runs on your machine.

CLI and JSON

Query usage from the terminal, or export a normalized JSON report for scripts.

whereToken reports token counts. It does not estimate monetary cost.

Installation

Recommended: Homebrew

brew tap rainhuang0220/wheretoken
brew install wheretoken

Prebuilt binaries

macOS and Linux:

curl -fsSL https://raw.githubusercontent.com/rainhuang0220/whereToken/main/scripts/install.sh | bash

Windows:

irm https://raw.githubusercontent.com/rainhuang0220/whereToken/main/scripts/install.ps1 | iex

The script prints the installed path (usually ~/.local/bin/wheretoken). Run that line. Open a new terminal if the command is not on PATH yet.

Build from source

go install github.com/rainhuang0220/whereToken/cmd/wheretoken@latest

Release binaries and brew tap include the dashboard. go install and brew --HEAD build the CLI only. To serve the dashboard from a clone, build the web UI (cd web && npm run build) and set WHERETOKEN_WEB to web/dist.

The npm/ wrapper is not on the npm registry yet.

Quick start

wheretoken

By agent	By provider

wheretoken --today
wheretoken --since 7d
wheretoken --json
wheretoken serve
wheretoken doctor
wheretoken rebuild
wheretoken update
wheretoken uninstall

wheretoken doctor explains which agents were found and whether their usage data is complete. wheretoken rebuild deletes the local scan cache and reads agent data again. Run wheretoken --help for the complete command reference.

Dashboard

Start the local dashboard with:

wheretoken serve

The dashboard runs locally on your machine. It provides a visual overview of token usage across supported coding agents, providers, and models. Use the refresh control in the page to rescan; reloading the browser tab does not.

Supported coding agents

whereToken reads usage information from data made available by supported coding agents. Completeness varies by tool and may depend on whether the application is signed in.

Coding agent	Usage data	Authentication
Claude Code	Full	Not required
Kimi Code	Full	Not required
Codex	Full	Not required
OpenCode	Full	Not required
Grok CLI	Full	Not required
Cursor	Partial	Required for token columns
Trae / Trae CN / TRAE SOLO	Partial	Required

Cursor and Trae must be signed in on this machine for token columns. Encrypted Trae storage is reported, not decrypted.

When a coding agent does not expose reliable usage information, whereToken reports the data as unavailable rather than treating it as zero. The dashboard labels each agent authoritative, degraded, estimated, or unavailable.

See docs/data-sources.md for how each agent is read and docs/token-accounting.md for the normalized token model.

Not currently supported

Windsurf, GitHub Copilot, Cline, and Lingma are not currently supported because whereToken does not yet have a reliable usage source for these tools.

How it works

Coding agents
      ↓
Local files and, for some agents, their own usage APIs
      ↓
Source-specific adapters
      ↓
Normalized usage data
      ↓
CLI / Dashboard / JSON

whereToken discovers usage information from supported coding agents, normalizes source-specific records into a common representation, and exposes the result through the CLI, dashboard, and JSON output. Later scans reuse a local file index as a cache only; wheretoken rebuild deletes that index and reads the agents again.

It distinguishes the coding agent you use from the provider that served the model.

A request made through Claude Code using a MiniMax model is reported as:

• Agent: Claude Code
• Provider: MiniMax

Privacy & Security

Local-first

whereToken is designed to operate locally and does not require a whereToken cloud service.

Data collection

whereToken does not upload usage data, session history, or credentials to a whereToken server. There is no telemetry.

Data sources

Usage information is read from data made available by supported coding agents. Most sources are local application data.

Cursor and Trae may access those applications' own APIs using credentials already stored by the corresponding application, to obtain token columns that are not present in the local files.

Credentials

whereToken does not ask users to paste API keys into the application. When an integration requires authentication, it uses local data or credentials already managed by that application.

Security policy

For security issues and the project's security policy, see SECURITY.md. Do not include API keys, session tokens, or other secrets in bug reports.

Limitations

whereToken is currently in alpha.

• Release binaries are currently unsigned (docs/macos-signing.md)
• An npm package is not currently published
• Some agents expose only partial usage information
• Some integrations require the corresponding application to be signed in
• The dashboard UI is currently Chinese-first
