I ran a security audit on my own Python codebase with an LLM for $0.90. Here is what it found.

Last week I shipped a small product called VibeScan - a 49-dollar PDF security audit for apps built with Lovable / Bolt / Cursor / Replit / v0. Before I asked anyone to pay for it, I ran it on my own codebase as a smoke test. 124 scannable Python files, 4 LLM batches, 22 seconds total wall time. Audit cost: $0.90 of Opus 4.7 with prompt caching. Output: 0 critical findings, 1 high, 2 medium. One of the findings was a real bug I fixed the same hour. The other two were legitimate risk flags I had not thought about. Here is the full report, with context on each finding.
