CodeBurn is a free, open-source tracker for AI coding costs. It reads the session files your tools already write - Claude Code, Cursor, Codex, Copilot, 40 in all, and shows every token and dollar by the task, model, project, and pull request that used it. The Optimize tab finds waste like cache bloat or retry tax, applies the fix, and tracks what it actually saved. Everything runs on your machine: no account, no uploads. MIT-licensed and genuinely free, used by 150k+ developers across the world.
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.
Hi everyone, I'm Resham, the maker of CodeBurn.
I built it because I was spending a lot on AI coding tools and could not answer a simple question: where did the money go? Claude Code, Codex and Cursor each showed me a bill, and none of them told me which project, which model or which task had spent it, or how much of it was wasted.
Every one of those tools keeps a session file on your machine. CodeBurn reads those files and turns them into one picture. What you spent today and this month, by tool, by model, by project, by branch and by task. Click any number and you see the sessions behind it. The Optimize page finds the waste and tells you the fix. The Plans page shows your limits before you hit them.
It runs on your machine. There is no account, no API key and no proxy. Your code and prompts stay on your computer.
What is in this launch:
- A desktop app for macOS, Windows and Linux
- A macOS menu bar, a Windows tray and the Capacity Dock, so today's cost and your plan limits are always one glance away
- Compare two periods side by side, and see what each branch cost
- 41 supported tools, in six languages
- npx codeburn if you just want the terminal
Next is CodeBurn Teams, the same picture for a whole team. Beta testing starts soon at codeburn.app/teams.
I read every comment. Tell me what is missing, what is wrong, and which tool you use that we do not read yet.
