About

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.

About

JavaScript Obfuscator Pro is an advanced code protection platform designed to secure JavaScript against reverse engineering and intellectual property theft. Its flagship VM obfuscation feature transforms readable JavaScript into custom bytecode executed by a proprietary virtual machine. This approach removes standard JavaScript structures entirely, making static analysis and decompilation extremely difficult. Each obfuscation run generates unique bytecode and a custom VM, ensuring no reusable deobfuscation patterns exist. JavaScript Obfuscator Pro supports layered security by combining VM obfuscation with additional protection techniques. The platform works through a simple web interface or API, allowing developers to protect code in just a few steps. JavaScript Obfuscator Pro is built for scenarios where maximum code secrecy is required.
