cctrack 0.1.0

Claude Code cost tracker — scans JSONL logs and reports token usage + estimated cost

cctrack

A lightweight CLI tool that scans Claude Code JSONL logs and reports token usage and estimated cost. Zero dependencies, runs anywhere Python 3.10+ is available.

Install

# Run directly (no install needed)
uvx cctrack

# Or install globally
uv tool install cctrack

Usage

# Scan local logs and print report
cctrack

# Last 7 days only
cctrack --days 7

# Aggregate with remote machines via SSH

What it does

1. Walks ~/.claude/projects/ and ~/.sandy/sandboxes/ for JSONL log files
2. Parses assistant events with token usage
3. Deduplicates by requestId (last event wins, matching Claude Code's semantics)
4. Calculates cost using Anthropic's published rates per model
5. Prints daily breakdown with input/output/cache token splits and monthly summaries

Remote aggregation

With --remote, cctrack SSHs to each host (one call per host) and streams back all JSONL content for local parsing. Requires SSH key auth.

# Aggregate this machine + DGX server + laptop
cctrack --remote dgx macbook-air

Rate card

Prices per million tokens, from Anthropic's pricing page:

Model	Input	Output	Cache Read	Cache Write
Opus 4.6 / 4.5	$5.00	$25.00	$0.50	$6.25
Opus 4 / 4.1	$15.00	$75.00	$1.50	$18.75
Sonnet 4.x	$3.00	$15.00	$0.30	$3.75
Haiku 4.5	$1.00	$5.00	$0.10	$1.25
Haiku 3.x	$0.80	$4.00	$0.08	$1.00

Unknown models fall back to Sonnet rates.

Origins

This is a Python rewrite of the Go-based cctrack dashboard. The Go version provides a full web dashboard with real-time updates, session explorer, and project breakdown. This Python version strips it down to the essentials: a single command that parses logs and prints a cost report. The JSONL parsing logic, deduplication strategy, and rate card are ported directly from the Go implementation.
