AWS bill spikes to $

AWS bill spikes to $

Original: My app didn't go "viral". My AWS bill did.

Short summary

An author debugged a surprising $31 AWS bill for a low-traffic app using Claude and Amazon Q, discovering the real culprit was a different AI agent project on the same account. The post explores how CloudTrail, token analysis, and complementary AI tools solved a cost attribution mystery.

  • Built free learning-path tool (Clew Directive) received 14 visits but AWS charged $31
  • Debugging revealed the bill came from a different project (vigil-crest Telegram agent) running on the same account
  • Used CloudTrail data, token cost patterns, and Claude's code reasoning to solve the mystery

Generated with AI, which can make mistakes.
