What this tool is for

Secret Leak Scanner highlights common credential-looking patterns before text is shared in prompts, tickets, or docs.

When to use it

Use it as a quick local check before pasting logs, environment examples, or error reports elsewhere.

What the result means

The result lists matched pattern types and line numbers. It is a heuristic scanner, not a guarantee.

Use notes

  • Review every finding manually.
  • False positives and false negatives are possible.
  • Rotate any real credential that was exposed outside approved systems.

Privacy and limits

Everything runs in your browser tab. Avoid pasting production secrets, private tokens, customer data, or proprietary code into any online page unless your team policy allows it.
