Token usage bugs are easiest to catch during the run, not after billing

Most teams still detect token waste too late.

You run experiments, iterate prompts, and only discover spend spikes when the dashboard updates.

What actually helps is a live signal while requests are in flight.

That’s why I built TokenBar for macOS: a menu bar token counter that makes usage drift visible in real time.

If you’re shipping AI features, try adding live usage visibility before your next optimization sprint:
