Private Local Inspection
Your sensitive tokens, database fields, and credentials are decomposed purely within client JavaScript memory. Zero external transmissions.
Zero-Width & Security Auditing
Instantly spots invisible characters (ZWSP, ZWNJ, BOM) often used in homograph attacks, copy-paste syntax tampering, and hidden watermarks.
Byte-Level Serialization
Displays variable-length UTF-8 encodings (1 to 4 bytes) alongside UTF-16 surrogate pairs for diagnosing encoding corruptions.
