About

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.

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

The Java™ Programming Language is a general-purpose, concurrent, strongly typed, class-based object-oriented language. It is normally compiled to the bytecode instruction set and binary format defined in the Java Virtual Machine Specification. In the Java programming language, all source code is first written in plain text files ending with the .java extension. Those source files are then compiled into .class files by the javac compiler. A .class file does not contain code that is native to your processor; it instead contains bytecodes — the machine language of the Java Virtual Machine1 (Java VM). The java launcher tool then runs your application with an instance of the Java Virtual Machine.

About

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.
