cctrack

A cost tracker for Claude Code. Parses your local JSONL logs, calculates spend per session/project/model, and serves a real-time dashboard — all from a single binary.

Features

• Cost tracking — today, this week, this month, and projected monthly spend
• Session explorer — browse every Claude Code session with token and cost breakdowns
• Project breakdown — see spend grouped by project, with monthly trends
• Model breakdown — usage and cost per model (Opus, Sonnet, Haiku)
• Activity heatmap — visualize when you're using Claude Code most
• Request timeline — per-request token usage within each session
• Real-time updates — file watcher + WebSocket push when new activity is detected
• Budget tracking — set a monthly budget and see progress against it
• Single binary — Go CLI with an embedded Vue 3 SPA, no separate frontend server needed

Installation

cd cctrack
cd web && npm install && npm run build && cd ..
go build -o cctrack .

Usage

Start the dashboard

cctrack serve

Opens a web dashboard on http://localhost:8877 with real-time cost tracking. Parses logs on startup and watches for new activity.

cctrack parse

Scans ~/.claude/projects/ for JSONL log files and updates the SQLite database.

Quick status

How it works

1. Claude Code writes JSONL logs to ~/.claude/projects/<project>/<session>.jsonl
2. cctrack scans these files, extracts token usage from assistant messages, and deduplicates by requestId
3. Costs are calculated using Anthropic's published per-token rates for each model
4. Data is stored in a local SQLite database (~/.config/cctrack/cctrack.db)
5. The serve command starts an HTTP server with a REST API and embedded Vue SPA
6. A file watcher detects new log activity and pushes updates via WebSocket

Configuration

Config is stored at ~/.config/cctrack/config.json:

{
  "log_dir": "~/.claude/projects",
  "db_path": "~/.config/cctrack/cctrack.db",
  "port": 8877,
  "monthly_budget_usd": 200,
  "open_browser_on_serve": true
}

All settings can also be changed from the dashboard's settings page.
