This paper introduced JSDeob-Port, a portable JavaScript deobfuscator and unpacker that operates across diverse runtime environments. By combining static AST preprocessing with a lightweight, pluggable dynamic sandbox, it achieves 94.2% unpacking success on real-world obfuscated samples while maintaining environment independence. The modular design allows security analysts to deploy it anywhere JavaScript runs – from cloud functions to embedded devices. Future work will focus on symbolic execution and machine learning-based identifier restoration.
A JavaScript deobfuscator and unpacker portable is a tool that can reverse the obfuscation process, making it possible to understand and modify the original code. A portable version of the tool means that it can be run from a USB drive or other portable device, without requiring installation on the local machine. javascript+deobfuscator+and+unpacker+portable

The state of portable JavaScript deobfuscation is mature, largely driven by the Node.js ecosystem and browser extension capabilities. Tools like and JStillery provide the best balance of power and portability. For analysts, the ability to run these tools offline via CLI or browser extensions is vital for rapid triage of web-based threats.
