API key leakage detection for live websites

Source Detector helps identify suspicious API key exposure patterns in JavaScript bundles and other client-side assets so you can review evidence before remediation or disclosure.

How Source Detector supports API key leakage detection

• Discover source maps and related client-side assets during browsing
• Scan assets with built-in and custom rules
• Inspect surrounding evidence in a structured explorer
• Export artifacts for offline validation and reporting

What counts as a leakage candidate

Leakage candidates may include hardcoded API keys, suspicious tokens, integration credentials, or secret-like strings embedded in frontend code. Manual context review is still required to separate real risk from harmless public identifiers.

Why evidence matters

For API key leakage detection, the string alone is not enough. You need surrounding context, file origin, and sometimes source map visibility to judge whether a finding is actionable.
