BlueClosure vs. JS-Confuser vs. Python vs. jsObf Comparison Chart

JS-Confuser is a powerful, open source JavaScript obfuscation tool that transforms your source code into a highly unreadable form, deterring reverse engineering, tampering, and unauthorized reuse while preserving full functionality. It offers multiple obfuscation techniques, including variable renaming, control flow flattening, string concealing, and function obfuscation, along with locks such as domain-based or date-based execution constraints and integrity checks to detect runtime modifications. Designed for flexibility, it provides obfuscation presets, ranging from 10 to 21+ transformation layers, and also allows fully customizable configurations to suit performance and protection needs. The tool operates entirely in the browser for fast, private obfuscation workflows, and includes advanced tooling features such as a playground for interactive experimentation, customizable options via JavaScript, integrated code prettification, and debugging support.

jsObf is a powerful, web-based JavaScript encryption and obfuscation tool that enables users to transform readable JavaScript code into obfuscated, secure versions via direct input or file uploads (up to 5 MB). It also serves developers through its API, offering two endpoints, one for raw code and another for file uploads, with configurable output formats (JSON or XML) and adjustable complexity levels. It simplifies protection workflows with intuitive, drag-and-drop interfaces and backend API support, empowering users to quickly mask logic, thwart reverse engineering, and secure proprietary scripts without complex setup or tooling.
