CodeBurn
See exactly where your AI coding tokens are spent
CodeBurn is a free, open-source tracker that shows exactly how much you spend on AI coding tools. It reads local session files from 41 tools, including Claude Code, Cursor, and Codex, and breaks down tokens and costs by model, project, task, and PR. Its Optimize feature finds waste such as duplicate reads, bloated context, and inefficient caching, then applies fixes. Everything runs locally with no account or data uploads.
