This report provides an overview of portable JavaScript deobfuscators and unpackers. In the landscape of cybersecurity and web development, analyzing obfuscated code is critical for threat detection and debugging. "Portable" tools—those requiring no installation (standalone executables, HTML/JS applications, or command-line binaries)—offer significant advantages for incident response teams and analysts working on locked-down systems. This report categorizes available tools, evaluates their efficacy, and highlights the best practices for their use.
