Dotfuscator vs. EndCrypt vs. JS-Confuser vs. JavaScript Comparison Chart

Application development teams face an ever-growing set of security threats as apps become more central to business and attackers grow in sophistication. These days, intellectual property theft is just the beginning – apps are also gateways to trade secret theft, customer/user data theft, and to identifying further attack vectors. Breaches in any of these areas can cause serious revenue, reputation, and brand damage. Sophisticated app dev organizations know that investing in app protection is good risk management. Basic renaming obfuscation isn’t enough. PreEmptive Protection Dotfuscator for .NET provides many layers of protection: multiple forms of obfuscation (renaming, string encryption, control flow, and more) plus active runtime checks (tamper, debug, root, and more). But it’s not just about protection – we design and test all these layers to be sure that they won’t break your app as the runtime platform evolves.

JS-Confuser is a powerful, open source JavaScript obfuscation tool that transforms your source code into a highly unreadable form, deterring reverse engineering, tampering, and unauthorized reuse while preserving full functionality. It offers multiple obfuscation techniques, including variable renaming, control flow flattening, string concealing, and function obfuscation, along with locks such as domain-based or date-based execution constraints and integrity checks to detect runtime modifications. Designed for flexibility, it provides obfuscation presets, ranging from 10 to 21+ transformation layers, and also allows fully customizable configurations to suit performance and protection needs. The tool operates entirely in the browser for fast, private obfuscation workflows, and includes advanced tooling features such as a playground for interactive experimentation, customizable options via JavaScript, integrated code prettification, and debugging support.
