A couple weeks ago I noticed my AI spend climbing while I was coding and there was zero visibility until the invoice hit.
So I built TokenBar: a macOS menu bar app that shows token usage and cost in real time while you work.
What it helps with:
- catching runaway prompt loops early
- seeing which sessions are expensive
- making model choice less blind
Price is $5 lifetime.
If you use Claude, Cursor, OpenAI, or OpenRouter daily and want to see spend before the invoice, take a look: https://tokenbar.site
