Your Claude bill or plan meter shows one number. It never tells you which project, which model or which habit ate it. This free, open-source tool, past 11,000 GitHub stars, reads the session files Claude Code already saves on your computer, prices every token, and shows you where it all went. Then it finds the waste and can fix it for you. No account, no sign-up: it all runs on your own computer.
Here's what it shows, how to set it up in a minute, and what it can't see.
What it does for you
- Breakdown: today's spend and the last 30 days, cut by project, model, task and even git branch.
- Sessions: click any total to see the session and the exact turns that were expensive.
- Optimize: lists what costs tokens without earning them (a file Claude rereads every turn, a tool you installed and never use, an instructions file long enough to ride along in every request), each with a grade, the fix and the saving.
- Fix and undo: it can apply those changes for you, backs up files first, and takes any change back.
- Plan left: shows how much of your Claude plan is used and whether the month is on pace to run past it.
- Guard (optional): warns a Claude Code session once it passes $5 and stops it at $15; you set the limits.
