How AI is used
JavaScript Obfuscator is a tool designed to make JavaScript source code difficult to understand or reverse-engineer. It offers two main methods: standard obfuscation, which runs in the browser, and VM protection, which transforms code into custom bytecode that executes on a virtual machine via server-side processing.
This tool is designed for developers and companies creating HTML5 games, SaaS applications, browser extensions, and licensed software. It helps protect intellectual property by transforming original logic into a format that static analysis tools may find difficult to interpret.
The software includes defense layers such as debug protection and countermeasures designed to disrupt AI-based code reconstruction. Buyers can choose from different presets to balance security levels against the performance impact on the application.
Buyers should confirm how the obfuscation affects their specific code performance, as VM protection may introduce a slowdown ranging from 3.5x to 20x depending on the preset used.
Key Features
VM Bytecode Conversion
Transforms JavaScript into custom bytecode that runs on an embedded virtual machine interpreter.
Self-Defending Code
Supports runtime integrity verification to help detect and neutralize modification or hook injection.
Debug Protection
Designed to restrict developer tools and breakpoints to make runtime inspection more difficult.
Anti-LLM Countermeasures
Includes defenses aimed at blocking AI agents from tracing and reconstructing the original code.
Selective Obfuscation
Supports applying VM protection only to specific functions using special comments to help manage performance.
Target Environment Selection
Supports output targets including web browsers, browsers with CSP restrictions, and Node.js.
Use Cases
HTML5 Game Protection
Supports the protection of game logic to help prevent cheating or code theft.
SaaS Proprietary Logic
Helps secure frontend algorithms and business logic in client-side applications.
Licensed Software Security
Supports the security of license validation and anti-piracy mechanisms.
Browser Extension Security
Helps shield extension source files from being copied or modified.
Integrations
- JSON import
- JSON export
FAQ
Can I use this tool to hide API keys in my frontend code?
- No. The vendor states that API keys and secrets should never be stored in frontend code, as obfuscation is not encryption and determined attackers can still extract data.
How does VM obfuscation affect the performance of my app?
- Performance varies by preset; low presets result in approximately 3.5x slower performance, while higher presets may cause more significant slowdowns.
Does the software support TypeScript?
- It does not support TypeScript or JSX directly; these must be compiled into JavaScript before they can be obfuscated.
What is the difference between the Free and Pro plans?
- The free plan has a 25MB lifetime VM quota, while the Pro plan ($19/month) provides a 100MB monthly quota and includes API access and batch obfuscation.
