What Is the JavaScript Obfuscation Detector?
This tool scans JavaScript and flags common obfuscation signals such as eval(), generated identifiers, heavy escaped literals, and array indirection. It gives a fast static report to help you prioritize manual review.
Analysis runs in your browser and does not execute the code. For cleanup, use JavaScript Deobfuscator. For packed wrappers, use JavaScript Unpacker.
