How I stopped getting surprised by my AI API bills
If you've built anything on top of GPT, Claude or Gemini, you've probably had the moment: everything's working, users are happy, and then the bill arrives and it's way more than you expected. The tricky part isn't the cost itself, it's not seeing it coming. Each provider shows spending in its own separate dashboard, so it's easy to miss what's adding up until the bill lands. So I built AI Spend…
Those who have developed applications using GPT, Claude or Gemini have likely experienced a moment of surprise when the bill arrives, far exceeding the initial expectations. The real challenge lies not in the cost itself, but in its unexpected nature. Each provider presents its spending data in a distinct dashboard, making it easy to overlook the accumulating expenses until the final bill is received. To address this issue, I developed AI Spend Tracker.
The tool seamlessly connects to major AI APIs including OpenAI, Anthropic, Gemini, Grok, OpenRouter, and DeepSeek, as well as any additional services entered manually. It calculates a single monthly total across all connected services and sends budget alerts via email, Slack, or Discord at predetermined thresholds. The tracker also detects abrupt increases in spending and warns users if they are on track to exceed their budget.
One technical aspect worth noting is that providers report costs differently. OpenAI and Anthropic offer cost report APIs, while Gemini lacks a straightforward method, prompting the tracker to utilize Google Cloud billing exports. DeepSeek only provides balance information, so the tool monitors the balance changes between check intervals.
A live demonstration of AI Spend Tracker is available on the homepage, requiring no registration: aispendtracker.online. The service is free for the use of a single provider, and I welcome suggestions on additional features to include.
