About

ByteHide is an all-in-one, developer-first application security platform designed to protect code, secrets, data, and runtime environments, while minimizing your dependencies and risk. It integrates seamlessly with your development workflows and communication tools, delivering key security insights and alerts without disrupting productivity. Operating under a zero-knowledge model, ByteHide uses client-side encryption so only you hold the keys, and it never stores your source code. With minimal, typically read-only permissions, you remain fully in control of what repositories and data sources are analyzed. ByteHide’s core tools include Shield for next-generation code obfuscation and anti-tampering, Secrets for AI-powered secret detection and decentralized management, Monitor for real-time runtime threat detection, and Radar for unified SAST/SCA scanning. These tools run in secure, isolated environments and automatically mask sensitive personal data.

About

Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities.

About

JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.

About

JavaScript Obfuscator transforms readable JavaScript source code into an obfuscated and unintelligible form, preventing reverse engineering, tampering, and intellectual property theft while preserving full functionality and compatibility with the latest ECMAScript versions. It includes powerful features such as minification and compression for reduced file size and faster load times, dead code insertion to confuse static analysis, and domain- or IP-based locking to disable code execution outside authorized environments. The tool provides GUI-driven desktop batch processing that allows users to protect JavaScript embedded in HTML, PHP, JSP, or similar files with just a few clicks, and supports keeping initial comments or inserting custom headers into output files. Advanced controls let you exclude certain names from obfuscation and ensure consistent symbol renaming across multiple files.
