Dotfuscator vs. JS-Confuser vs. JavaScript vs. PreEmptive Protection for iOS 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.
