Why JScrambler?

What can happen to your business if you leave your Javascript code unprotected?

Reputation Loss

Your online reputation is one of your most valuable assets. JScrambler helps you keep your applications safe and less vulnerable to fraud or any other attacks. How much do you value your reputation?
Competition Loss

Some of your main competitors may be interested in inspecting your code, because you have a specific algorithm, or just to speed-up their development process. Do you want to make it easy for them?
Business Loss

You invested a lot in the development of your application, and of course you want to profit from it, but what if someone changes your code and uses it for free?

You invested a lot of time in developing your JS code.
Why give it away for free?

What is it good for?

Enhance the Security
of your Application

If you develop a security sensitive Web Application we believe that you don't want to give any bonuses to possible attackers. JScrambler enables you to conceal as much as possible, the logic of your application, such as what information is gathered from the user, how it is processed on the client-side, how it is sent to the servers-side. Since our obfuscation introduces a certain level of randomness, it allows you to explore code morphing techniques, which can be vital in precluding attack automation.
Protect your Intellectual Property

You've developed an algorithm that executes as client-side JavaScript and you want to make sure it is safe. Our advanced JavaScript obfuscation hides your algorithm and frustrates competitors that try to steal your algorithm. Development and production versions of your code shouldn't be the same, you can also use our solution to deploy protected versions of your code.
Enforce License Agreements

If you develop and sell JavaScript applications, be it standard JavaScript, Mobile Web Applications or HTML5 Canvas, you’ll want to prevent that someone that didn’t paid or whose license has expired to execute your code. With our solution, you can lock your code to a predefined list of domains. If someone place it anywhere else, it will not execute correctly. You can also use the Expiration Date to deliver expirable demos to your clients without incurring in the fear of code or client-loss.
Make your
Application Faster

We deliver code optimisation transformations that make your code smaller and faster to load. Our code transformations are tweaked and optimised according to your application type and performance requirements. For instance, Mobile Web Applications cannot undertake the same degree of obfuscation that a standard JavaScript application running on a powerful CPU can.

What tricks do we
have up our sleeves?

MINIFICATION & COMPRESSION

Removes all unnecessary characters from source code without changing its functionality.
OPTIMIZATION

Optimizes the code in terms of computational performance, but this technique is not meant to provide any protection to the code.
OBFUSCATION

Consists in the transformation of the source code, making it harder to understand without changing its original functionality.
CODE TRAPS

Set of checks throughout the code that forces the application to execute only in certain domains, OS and browsers. It also makes the code expire on a set date.
SELF-DEFENDING

Provides JS applications with self-defending capabilities, offering them extra resilience when under tampering attacks.

We have solutions for:

Mobile
Developers

JScrambler relies on JavaScript Obfuscation but, contrary to other solutions, it has been tailored to give your applications the best protection on devices with limited resources.

With JScrambler you get protection and optimisation in a single step. Try it now.
Web
Developers

Due to the evolution of many JavaScript frameworks, Web applications are getting more rich and interactive. But this also means that more code becomes exposed to theft.

JScrambler is the right solution to protect your JavaScript! Try it now.
Game
Developers

Browsers and computers are now capable of performing complex 3D operations and allow an desktop-like gaming experience. However, most of the computation is performed in the client-side using JavaScript which is sent in clear-text. This causes the game code to be exposed, placing your business at risk.

JScrambler is the right solution to protect your JavaScript! Try it now.
HTML5
Developers

HTML5 is taking us to a paradigm shift, from applications that concentrate most of the logic on the server-side, to applications that execute mostly on the client-side. This calls for new levels of code protection.

JScrambler is the right solution to protect your HTML5! Try it now.
Node.js
Developers

Whether you’re working on a library distributed through NPM, a standalone client or a browser application, Node.js is still sent or installed in clear-text in the end-user device. If are using shared or hosted servers your code may be at risk.
