TokenWatch connects to your OpenAI, Anthropic, and Gemini keys and gives you: - Real-time spend dashboard across projects - Budget thresholds with proactive alerts - Anomaly detection for unusual cost spikes - Duplicate call detection (biggest source of wasted spend I've seen)
Free tier supports up to 3 AI systems. Built this in ~2 days as a solo project. Happy to answer anything about the build or the problem space.
