OpenAI API Cost Tracker

If you're using the OpenAI API across multiple models, it's surprisingly easy to lose track of where your money is actually going. This minimalist open-source tool gives you a clear picture of your daily usage and cost breakdown across all your models — no guesswork involved.

It covers ChatGPT, GPT-4, Whisper, text-embedding models, and more, letting you see cost proportions at a glance either by time or through a clean pie chart. Best of all, it's completely open-source and your API key stays on your device — no data leaks, no privacy concerns. Just straightforward visibility into your OpenAI spending.
