JS-Confuser vs. JavaScript vs. QShield vs. cloverage 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.

Obfuscate your highly valuable source code and protect your sensitive assets thanks to QShield compiler-obfuscator. Protect your applications against static and dynamic analysis. Software running on untrusted environments is at risk of reverse-engineering, an application running on a device that is available to an attacker is vulnerable to a wide range of techniques used to try and extract secrets, and intellectual property. To prevent unauthorized parties from gaining insight, tampering with or even recovering the source code from the binary, software protection mechanisms must be implemented to preserve revenues and intellectual property. 30+ obfuscation schemes are available. Granular control of the protection profile thanks to a file-based policy or comments throughout the code. Build diversification, each compiled application is different with a user-controlled randomness seed. Integrity checks and detection of debuggers, emulators, and hooking frameworks.
