✨ Features
🔒 Completely local. Reads the transcripts already on your disk. Makes zero network requests — no telemetry, no account, no API keys.
💸 Real cost estimates. Turns raw token counts into dollar figures using a transparent, editable pricing table.
🧩 Breakdowns that matter. See your burn split by model and by project, so you know exactly where the tokens went.
⚡ Prompt-cache insight. Surfaces your cache read-hit rate — the single biggest lever on what you actually pay.
🖼️ Beautiful HTML dashboard. --html writes a self-contained, offline dashboard you can open in any browser or share.
🪶 Tiny & dependency-free at runtime. A ~15 KB bundle with no runtime dependencies. Nothing to trust but the code you can read here.
🚀 Quick start
You'll need Node.js 20+ and some Claude Code usage on this machine.
Run it instantly with npx
npx github:amiinwani/whoburnedmore.com
Or clone and run
git clone https://github.com/amiinwani/whoburnedmore.com.git cd whoburnedmore.com npm install # also builds the CLI npm start # == node dist/cli.js
📖 Usage
whoburnedmore # print your burn report whoburnedmore --html # also write ./whoburnedmore.html whoburnedmore --html out.html # ...to a custom path whoburnedmore --since 30 # only count the last 30 days whoburnedmore --dir # read transcripts from a custom directory whoburnedmore --json # raw aggregated JSON (pipe it anywhere) whoburnedmore --version whoburnedmore --help
Flag What it does
--html [file] Write a self-contained HTML dashboard (default ./whoburnedmore.html).
--since Only include usage from the last N days.
--dir Point at a custom transcripts directory instead of ~/.claude/projects.
--json Print the aggregated data as JSON instead of the report.
--version / --help Print the version / help.
🔍 How it works
Claude Code stores one JSON Lines transcript per session under:
~/.claude/projects//.jsonl
Every assistant turn in those files carries a usage block — input tokens, output tokens, and the prompt-cache read/write counts — plus the model name and a timestamp. whoburnedmore streams through those files line by line, adds the counts up by model, by project, and by day, multiplies by a public pricing table for a dollar estimate, and draws the report. That's the whole trick. The code is small on purpose — start with src/scan.ts.
🛡️ Privacy
This tool is read-only and offline by design.
It only reads files; it never writes to your transcripts or deletes anything.
It makes no network requests of any kind — no analytics, no "phone home," no auto-update.
The optional HTML dashboard is fully self-contained: no external fonts, scripts, or trackers.
Your prompts and code are never parsed for content — only the numeric usage counters and the model name are read.
Want to verify? It's ~400 lines. Read src/, or run with --json and inspect exactly what it computes.
🌐 The hosted version
This CLI is the open-source, local-only sibling of whoburnedmore.com — a public leaderboard where developers compare how much they've burned across Claude Code, Codex, Cursor and more. The website is a separate, hosted product; this repository contains only the local tool and none of its backend.
🤝 Contributing
Issues and PRs welcome — see CONTRIBUTING.md. Good first contributions: add models to the pricing table, support more agents' transcript formats, or improve the dashboard.
npm install # install + build npm test # run the unit tests npm run typecheck # strict type check npm run build # bundle to dist/cli.js
