CodeBurn
Breaks down your AI coding spend by tool, model, and project from files already on your disk.
CodeBurn is a free, open-source, local-first CLI/desktop/menubar app that reads the session files Claude Code, Cursor, Codex, Gemini, Grok and 36 other tools already write to disk, then breaks every token and dollar down by task, model, tool, and project. Everything runs locally — no proxy, no API keys collected, nothing leaves your machine — and pricing data comes from LiteLLM, refreshed daily. A single `npx codeburn` opens the dashboard in seconds with no install required.
What holds up
- +Runs entirely local — no proxy or API keys needed, since it just reads files already on disk.
- +Free and open source, covering 41 AI coding tools including Claude Code, Cursor, and Codex.
- +`npx codeburn` opens a working dashboard in seconds, with no install step required.
- +Breaks spend down by task and model, showing when a cheaper model would've one-shot the same work.
Mind the limits
- −Only as accurate as the session files each tool writes — a tool without local logs won't show up.
- −Needs Node.js 22.13+ installed, so it's not usable without a working dev environment.
