Score: 7.0/10 (Innovation: 7, Technical: 6, Documentation: 8, Utility: 7)

CodeBurn is a tool that analyzes token usage across multiple AI coding assistants (Claude Code, Codex, Cursor, etc.) by reading session data directly from disk. It's interesting because it provides detailed cost breakdowns, success rate metrics, and activity classification without requiring API keys or proxies, helping developers optimize their AI coding expenses.

Target audience: backend devs, frontend devs, data engineers
