TokenTelemetry — See exactly what your Claude Code, codex, gemini cli and 6 more coding agents sessions cost, think, and do (100% local, open source)

[VasiHemanth]

Hey cc-switch community!

If you're switching between Claude models to optimize performance and cost, you probably ask yourself: "How much did that session actually cost me?" or "What was Claude actually doing under the hood?"

I built TokenTelemetry to answer exactly that — a 100% local, open-source observability tool for AI coding agents.

What it does

• Tracks token usage, cost, reasoning traces, and subagent activity in real-time
• Works with Claude Code, Codex, Gemini CLI, Cursor, Copilot, and 5 more — zero config
• Reads directly from local agent log files (no proxies, no cloud, no signup)
• One dashboard to see every agent, every session, every model

Why it pairs well with cc-switch

cc-switch lets you swap between Claude models on the fly. TokenTelemetry lets you see the impact of those switches — compare token burn and cost across claude-opus-4-7 vs claude-sonnet vs other models session by session. Great for understanding which model gives you the best value for a given task.

Would love feedback from power users here — especially if you notice anything specific to multi-model sessions that would be useful to track. Happy to discuss!
