Analyze your own Claude Code session cost, in the browser

Pick your ~/.claude/projects folder (or any .jsonl session files). The analysis runs entirely in this tab: nothing is uploaded, no request is made; it reads only the usage fields and content lengths, exactly like the published anatomy.

On macOS, in the picker press ⌘⇧G and paste ~/.claude/projects. Large folders (hundreds of MB) take under a minute.

The kit: measure your own sessions and the market, weekly

Session cost anatomy for your own logs (quota_report.py): the exact report on this site, on your machine, one command; reads only usage fields and lengths.
Demand simulator (demand_sim.py + priors + calibration): live connectors for GitHub, npm, VS Code Marketplace, WordPress.org, Hacker News, Apify, MCP registry, Hugging Face; scores what a solo newcomer reached at each attach-point in the last 24 months, calibrated against six real product outcomes before it scores anything.
This week's datasets: every table on this site as JSON and TSV, the plugin marketplace catalog, the issue gap maps, the 50-candidate scoring run with every verdict and its deciding number.

$39, one time. Regenerated weekly for a year; the download link you get keeps serving the newest build. MIT.
