What is Obfuscation?

JavaScript code obfuscation is a series of code transformations that turn your exposed code into a protected version of the code that is extremely hard to understand and reverse-engineer.

Not to be mistaken with Minification (that solely optimizes the code) or Encryption (as there is no password to decrypt the obfuscated code).

Jscrambler goes beyond Obfuscation

Advanced obfuscation techniques

While most tools only offer basic obfuscation, Jscrambler applies the most advanced and resilient obfuscation techniques. Jscrambler will never break your code or add malware.

Runtime protection and countermeasures

Jscrambler provides the most complete JavaScript code protection with code locks, self-defending capabilities and customizable countermeasures.

The risks of not using JS Obfuscation

Stolen Intellectual Property

You spent thousands of hours writing your code to create something unique. Without proper security measures, your IP and competitive advantages will be compromised.

Piracy and License Violations

Your JavaScript Code can be reverse-engineered to remove protections and violate your license agreement. Your product and business model will be at risk.

How our advanced Obfuscation of code works

Combined Obfuscation Techniques

Jscrambler combines transformations to Strings, Variables, Functions, and Objects, through reordering, encoding, splitting, renaming, and logic concealing techniques.

Control-flow Flattening

Control-flow Flattening obfuscates the program's control-flow by adding opaque predicates, flattening the control-flow, and adding irrelevant code clones. This makes it much harder to reverse-engineer the protected code.

Polymorphic JavaScript Obfuscation

Each time you deploy a new version of your code, you get a different protected output. This means that you can frequently deploy different protected versions, making the reverse-engineering process unfeasible.

Self-Defending Capabilities

With Jscrambler’s runtime protection, your app will detect debugging attempts and prevent code analysis at runtime. Plus, if attackers try to tamper with the code, Jscrambler will break it on purpose.

Jscrambler Performance

How does this impact JavaScript Performance?

All Jscrambler transformations are developed to have the least possible impact. The performance hits are manageable and depend a lot on the application you are trying to protect. You can fine-tune your protection on the most sensitive parts and apply it more where it is most needed. Plus, Jscrambler's Profiling feature allows you to easily apply different levels of protection on different parts of the code, for the best balance between security and performance.
