CodeBurn

Your AI coding bill is one number. CodeBurn tells you which project, which model and which task spent it, and how much was wasted. It reads the session files your tools already keep on disk, with no account, no API keys and nothing to set up. Works with Claude Code, Codex, Cursor, Copilot, Gemini and 36 more. Desktop app, menu bar, Windows tray and terminal. Free, open source, and your data stays on your machine.
