About
AI coding assistants have become a real cost, but the invoice is one line. CodeBurn reads the session logs your AI coding tools already write on your machine and turns them into itemized cost analytics: by project, model, session, day, and pull request. Everything runs locally. No API keys, no account, no data leaving your machine. - Works with 40 tools: Claude Code, Codex, Cursor, Copilot, Gemini, Kimi Code, Qwen, and more - Overview with spend, streaks, activity heatmap, and an efficiency score - Every session listed with its cost, models, turns, and tokens - Pull request attribution: what each PR cost to build - Spend flow from model to project, plus an hour-by-weekday punchcard - Optimize: findings that show where money is being wasted - Model comparison: head-to-head cost and efficiency
