Customer Data Leak Checker for Next.js Teams
Blocks pull requests that let one customer see another's data.
One missing customer filter shows a company's data to another, and a pentest near $4 000 often finds it. This tool blocks that pull request.

In their words
What worries me more is the stuff that doesn't break loudly. No error, no crash, it just quietly leaks data or accepts requests it shouldn't.
most security checks still happen once the pull request is already open. At that point the agent or developer has moved on, and the fix is more likely to become another ticket.
If our application leaks patient data we basically die both from fines and loss of trust from clients
The pain point it solves: AI Code Review Burden
AI-generated code is unreliable, bloated, and poorly understood, forcing developers into heavy manual review, debugging, and rework before it can ship.

Tools they use today

- Codex
- Cursor
- ChatGPT
- Copilot
- Lovable
- GitHub Copilot
Why those fall short
- AI can't hold full context; devs can't guide it to reuse modules
- Claude Code shows no per-line accept/deny; reviewing is manual and inefficient
- cannot keep complex modular project in context; useless where precision matters
- cannot stop the verbosity or jargon; instructions and skills ignored
- generates bloated code, lacks codebase context, requires thorough review
