Your AI built it.
Did anyone check if it's safe?
A December 2025 Carnegie Mellon study found AI coding agents write code that works 61% of the time - but only 10.5% of that working code is actually secure. This audit gives you 12 specific checks to run on your own Supabase + Stripe app before real users or real payments touch it.

The Problem
“It works” and “it's safe” are not the same thing
If you built your app with Claude Code, Codex, Cursor, Bolt, Lovable, or Replit, there's a real chance it passed every test you ran - and is still leaking customer data or exposed to fraud right now.
This isn't a knock on AI coding tools. It's how they're built to behave: they optimize for “the demo works,” not “this is safe in front of strangers on the internet.” Security gaps are invisible in a working demo. They only matter the moment someone with bad intent shows up - and by then, it's not a checklist item anymore, it's an incident.

Who This Is For
Built with Claude Code? This audit was made for you.
This is for non-technical founders and indie builders who shipped something real with AI and want to know - honestly - whether it's safe before more people start using it.
It's not a replacement for a professional security review. If you're handling regulated data or processing serious payment volume, pair this with a qualified security professional. But for everyone else, this catches the gaps that are easy to miss when you didn't write the code by hand.
FAQ
Q: I'm not technical at all - will I understand this?
A: Yes. Every check is written in plain English first, with the technical detail underneath for when you need it. If you can follow a recipe, you can follow this.
Q: Do I need to already know Supabase or Stripe?
A: No. The guide tells you exactly where to click in each dashboard, with real screenshots showing you what to look for.
Q: What if I find something wrong?
A: Every single check comes with a ready-to-paste prompt for Claude Code or Codex that fixes that specific issue. You don't need to write any code yourself.
Q: Is this a one-time check or something I keep using?
A: Keep it. Re-run the audit any time you add a new table, a new payment flow, or before a big launch. The scorecard is designed to be reused.
