Frontend secret scanner for exposed API keys and risky client-side assets

Source Detector helps you scan live frontend assets for exposed API keys, suspicious tokens, public configuration clues, and other risky client-side patterns that deserve manual review.

What it helps detect

• Exposed API keys embedded in JavaScript bundles
• AI-related tokens and suspicious credential patterns
• Public configuration clues that may expand attack-surface visibility
• Client-side strings worth validating during security review

Why use a frontend secret scanner

Modern websites ship a large amount of JavaScript, configuration, and third-party integration logic to the browser. A frontend secret scanner helps you find risky patterns faster than manual source inspection alone.

Important boundary

Not every exposed string is a secret, and not every public key is a vulnerability. Source Detector helps surface suspicious evidence, but findings still require human validation.

Best fit

This workflow is especially useful for security researchers, bug bounty hunters, and engineering teams auditing what production pages reveal to the public.
