codeburn

getagentseal/codeburn is an open-source project by getagentseal: Free, local tool to track AI coding token usage and cost across 37 tools and agents (Claude Code, Cursor, Codex, Gemini and more), by model, project, and task. npx codeburn. Indexed here so it can be found — not resold.

It is free. Get it from the upstream repository: https://github.com/getagentseal/codeburn

From the project's own README (excerpt, reproduced for discovery under its MIT license):

See where your AI spend goes.

If CodeBurn shows you something your bill never did, star the repo so other developers find it, and consider sponsoring to keep 41 integrations honest.

npx codeburn

To keep it: npm install -g codeburn or brew install codeburn . Needs Node.js 22.13+.

Desktop app 0.9.25. The macOS builds are signed with a Developer ID and notarized by Apple.

The problem

Your bill gives you a month total. It does not break that down by project, by model or by task, and it does not show which part of it was wasted.

Claude Code, Codex, Cursor and the rest each write a session file every time you use them, and those files hold every token and every model call. CodeBurn reads those files and produces the breakdown.

Desktop app, macOS menu bar, Capacity Dock and the Claude glance card, one engine behind all of them.

Sixty seconds

There is no account and no sign-up. CodeBurn looks in the folders your tools already write to, prices every token, and prints what you spent.

Under the total are the tables: cost by tool, by model, by project and by task. Task means what the agent was doing, such as coding, debugging or planning, worked out from the session itself.

Arrow keys move the period, from today out to your whole history. Press p to switch between tools. Press q to quit.

See it

The desktop app is the same data with room to move around in. It opens on today: what you have spent, what the month is on pace to cost, and the last thirty days day by day.

One click from the clock, the menu bar popover shows the short version of that page. The Capacity Dock adds a ring per provider at the screen edge. Hover a ring and a glance card tells you what is running right now and which limits are…
