Your AI coding agents bill you monthly and tell you nothing. TokenFlow reads the logs Claude Code, Codex, Cursor and Cline write on your machine, prices every branch, and posts the cost on the pull request as a comment plus a status check — so a change over its declared budget fails before it merges. A guard hook brakes a session while it is still running, and an MCP server hands the same numbers to the agent spending the money. Local-first, zero dependencies, MIT. Nothing leaves your machine.

TokenFlow turns local logs from Claude Code, Codex, Cursor, Cline, and Hermes into honest token and cost analytics -12 dashboard views, a native macOS menu bar app, forecasts, and anomaly alerts. Zero dependencies; nothing leaves your machine. Nothing leaves your machine.
