    Frequently Asked Questions

    Is this tool really free?

    Yes, completely free. We built this to help the developer community stay secure.

    Do you store my code or URLs?

    No. We only scan publicly accessible URLs. We don't store your code, URLs, or any detected credentials. Everything is processed in real-time and discarded.

    What if I find API keys exposed?

    Immediately rotate (replace) any exposed keys in your service dashboards. Then update your code to use environment variables instead of hardcoded credentials.

    Does this work with AI-generated code?

    Yes! This tool is specifically designed for apps built with Lovable, Cursor, Bolt, v0, and other AI coding assistants where API keys often get accidentally hardcoded.
