Features

• JavaScript Obfuscators - Provides a CLI to automate the transformation of JavaScript source code using various security presets.
• Code Obfuscators - Provides a professional tool to transform source code into a complex, unreadable format to prevent reverse engineering.
• JavaScript AST Transformations - Performs structural modifications of JavaScript source code using abstract syntax tree transformations.
• Dead Code Injection - Inserts non-functional code segments into the AST to confuse static analysis tools.
• Identifier Mangling - Replaces variable and function names with mangled or hexadecimal identifiers to hide original logic.
• String Literal Obfuscation - Hides constant string values by replacing them with runtime-resolved decryption expressions.
• Bytecode Virtual Machines - Compiles functions into custom bytecode executed by an embedded virtual machine to hide logic.
• Control Flow Flattening - Restructures program execution paths into a central switch statement to obscure original logic.
• Anti-Debugging Implementations - Implements logic to detect attached debuggers and trigger crashes to prevent code analysis.
• String Literal Obfuscation - Extracts strings into a special array and encodes them to prevent static analysis of text.
• Code Tamper Protections - Inject defenses that freeze developer tools and break execution if the source is beautified or hooked.
• Debugger Detection - Injects protections that detect attached debuggers and freeze browser developer tools.
• Reverse Engineering Prevention - Applies techniques like control flow flattening and dead code injection to hinder the analysis of program logic.
• Self-Defending Code - Inserts mechanisms that crash the application if the source code is beautified or modified.
• Source Code Protection - Transforms JavaScript source code into a version that is difficult for humans to read to protect intellectual property.
• Self-Defending Code - Injects self-defending mechanisms that cause the code to crash if the source is formatted or modified.
• File Management CLI Tools - Provides CLI tools for recursively traversing and processing files and directories for obfuscation.
• Cross-File Identifier Synchronization - Uses a naming cache and unique prefixes to ensure consistent identifier replacement across multiple files.
• Exclusion Lists - Exclude chosen variable or function names from obfuscation to maintain compatibility with external APIs.
• HTML - Obfuscates JavaScript inside HTML script tags while preserving the surrounding HTML structure.
• Domain Access Restrictions - Restricts code execution to authorized hostnames or domains to prevent unauthorized usage.
• Domain Locking - Injects runtime checks that validate the current window location against authorized domains.
• SDK License Enforcers - Restricts the execution of JavaScript to specific domains or environments to prevent unauthorized usage.
• Numeric Obfuscations - Replace static numeric values with complex mathematical expressions that evaluate to the original number.
• Batch Obfuscation - Processes multiple source files simultaneously while maintaining consistent identifier mapping through a shared cache.
• Identifier Mapping Caches - Maintains a mapping of original names to obfuscated versions across multiple files to ensure consistency.
• Batch Source Processing - Processes multiple source files simultaneously while maintaining consistent identifier mapping through a shared cache.
• Code Optimization - Advanced obfuscation for JavaScript and Node.js.
