Babel Obfuscator vs. JSDefender vs. JavaScript vs. ProGuard Comparison Chart

Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities.

ProGuard: Open Source Optimizer for Java and Kotlin. ProGuard is the most popular optimizer for Java bytecode. ProGuard also provides minimal protection against reverse engineering by obfuscating the names of classes, fields and methods. ProGuard reduces the download and startup time of Android applications and improves their performance on mobile devices. ProGuard obfuscates Java applications and pre-verifies the processed code for Java Micro Edition and for Java 6 and higher. ProGuard optimizes and obfuscates Java applications for cell phones, Blu-ray players, set-top boxes and other constrained devices. ProGuard fully supports Java and Kotlin applications, enabling developers to take full advantage of these languages’ features without sacrificing performance or security. ProGuard is a command-line tool with an optional graphical user interface. ProGuard is fast: It processes small Android applications and entire runtime libraries in seconds.
