Obfuscator is a free, open-source tool that helps you in obfuscating your code and protects it from being stolen, and no one can use it without permission. Is the only requirement for this tool is to have a compiler in order to compile the generated file. Obfuscator is language-independent, so it can be used to obfuscate any kind of code. The tool comes with the ability to transform your original JavaScript source code into a new object which is unable to comprehend, copy, or reuse, and if you don’t have the proper authorization, you cannot modify it.

The utility is mainly used to protect the source code of open source projects, proprietary code, and single-purpose programming. The only Obfuscator also allows you to specify custom command-line arguments for the generated files. Just all is required to paste the code, or you can upload it and click on the Obfuscate button. Obfuscator is written in C++ and uses wxWidgets as a GUI library, and is released under GPL license.

This utility protects your computer from and will encode your source code so that no one steals ideas or information. The software works by scrambling or harming computer code so that it is unreadable for humans.
With the obfuscator, you can protect your computer without any hassle whatsoever while still allowing it to be easy to use for others. It is commonly used to hide the specific details of proprietary software, preventing others from reusing parts of the work without permission. This is important for protecting both programs and their users

TerserFree
Terser is an all-in-one JavaScript parser and mangler or compressor toolkit for ES6+ that enables you to write clear and concise code. It was built with performance in mind and is extensively benchmarked. It comes with a super-fast parser for common JavaScript features, including JSON, comments, functions, classes & objects. This open-source program can be configured to use a custom AST for better performance and is designed to be used as a build step.

DomainLockJSFree
DomainLockJS is a free-to-use script generator that prevents script theft by domain-locking Javascript files to your website domain name. It means that when someone visits your website, they will see that Javascript file instead of the one they are trying to steal. You can create a DomainLockJS snippet and then put it into your HTML document, and the generated Javascript file becomes locked to your website domain name.
You can then choose to lock or unlock this file at any time. However, you must be careful to do so in a secure way. DomainLockJS works by attaching the DomainLock script tag to your HTML document. When someone tries to steal your JavaScript file, they will see the DomainLock script tag instead. The stolen code can be used to create disasters on your site or manipulate viewers. There are multiple features for you that include lightweight, simple copy protection, prevent script hotlinking, useful for software licensing, and more to add.

uglifyjsFree
The uglifyjs package is a JavaScript parser, mangler or compressor, and beautifier toolkit. It makes JavaScript code smaller and therefore helps make your pages load faster. This library is written in JavaScript and can be used standalone or combined with other tools and frameworks.
You can use this tool from the command line, but the most powerful way to use it is via the API that it provides. You can then integrate this with your build tool or existing application. In that case, you should familiarize yourself with the API documentation. This code generator framework works by outputting the JavaScript code from an AST and leverage with the functionality of the source map.

GnirtsFree
Gnirts is a JavaScript library for obfuscating string literals by encoding them as different string literals. This utility comes with the quickest way to easily obfuscate your string literals. One thing is worth mentioning here that Gnirts is not suited for the production of obfuscated code with a compiler. Gnirts comes with an effortless approach to mangles strings literals via using the code rather than using a hexadecimal escape.
Gnirts is designed to produce strings that are human-readable but not easily decipherable to machine analysis. Because of this, Gnirts should be able to produce strings that can safely be used in all JavaScript contexts. The good thing about this open-source utility is that you can easily find out the string literals that are escaped by the hexadecimal escape and decode them with ease.

Obfuscator-loaderFree
Obfuscator-loader is an all-in-one module loader that has the capability to Obfuscate module sources using Javascript Obfuscator. This tool is used with Node.js that has the capability to obfuscate module sources using Javascript Obfuscator. This means you can use it with Node.js to load modules from your project, export them to Javascript for use with Node.js,
You can also create Javascript Obfuscated versions of those modules for use by other tools that require Javascript Obfuscator ready files. In order to create a link between Node.js and obfuscator-loader, you need to require a configuration file. In brief, it loads, obfuscates, and exports modules from different sources in one process without requiring any extra steps.

Closure CompilerFree
Closure Compiler is a tool that makes Javascript download and run faster. It does this by removing unused code from the application, optimizing object properties, and replacing loops with if statements. Closure Compiler was created by Google to help improve the performance of their own web applications. The compiler does not remove comments or formatting information in your code, so you can still read and understand your code after it has been processed.
The Closure Compiler not only makes applications run faster, but its increased efficiency also reduces file sizes, making it a great solution for reducing bandwidth usage and loading time. Closure Compiler is compatible with many development environments and can be integrated seamlessly into most build tools such as Ant, Maven, and Visual Studio. The Closure Compiler API is designed to be used within other programming languages such as Python or Java, giving it a very high level of compatibility. There is also a command-line interface for those who prefer to stay at the command line.

YUI CompressorFree
YUI Compressor is a manifier that is just a tool that compresses code, allowing you to yield a higher compression ratio. This can be helpful when you’re embedding JS in HTML because it saves on file size. YUI Compressor is one of the few manifiers that add additional compression to the tokenization process without increasing file size. Courtesy of its parsing ability to parses your script first so it can do more than just guessing at how to optimize your code.
YUI Compressor is more configurable, so you can use more or fewer loader plugins depending on controlling requirements. Installing YUI Compressor is easy; you just need to download the SDK or zip, or unzip it, and drag all the files into your javascript folder. Moreover, the tool is also able to compress CSS files via using a CSS minifier.
