Frequently Asked Questions

What security vulnerabilities does this detect?

The scanner looks for XSS vulnerabilities, SQL injection patterns, hardcoded passwords or API keys, insecure random number usage, unvalidated user input, and missing error handling.

Is my code sent to a server?

No. All analysis runs entirely in your browser using pattern matching. Your code is never transmitted to any server.

Does this replace a full security audit?

No. This tool catches common, known vulnerability patterns. For production security, always pair this with a full professional code review and penetration testing.
