How do you keep track of AI API costs while building your product?

As AI becomes part of almost every product, I've realized that tracking AI API costs is much harder than I expected.

Most of us monitor uptime, errors, and performance—but when it comes to AI spending, many developers only discover the real cost when the monthly invoice arrives.

While building AICostPass, I kept asking myself:

• How are developers tracking OpenAI, Anthropic, Gemini, or Groq costs today?

• Are you relying on provider dashboards?

• Do you use spreadsheets, cloud budget alerts, or another tool?

• Have you ever been surprised by an AI API bill?

I'm especially interested in hearing from:

• Solo developers

• Indie hackers

• SaaS founders

• Agencies building AI products

I'd love to learn how you're solving this problem today and what features you wish existed in an AI cost management tool.

Your feedback will directly influence what we build next.
