About CodeBurn
CodeBurn is a free, open-source utility designed to help developers track and optimize their AI coding expenditures. As AI-powered development tools become a standard part of the software engineering workflow, tracking the actual financial cost and token usage of these services can be difficult. CodeBurn solves this by reading the session files that your existing tools already write.
The tool supports over 40 popular AI coding assistants, including Claude Code, Cursor, Codex, and Copilot. By analyzing local session files, CodeBurn breaks down every single token and dollar spent, categorizing the cost by specific tasks, LLM models, projects, and pull requests.
Key features of CodeBurn include:
- The Optimize Tab: Quickly identifies common sources of waste, such as cache bloat and retry taxes, applies automated fixes, and tracks exactly how much money those fixes saved.
- Complete Local Privacy: Because everything runs entirely on your local machine, there are no accounts to create and no data uploads required. Your code and session data remain entirely secure.
- Open Source & Free: Published under the MIT license, CodeBurn is completely free and is already trusted by more than 150,000 developers worldwide.
