wtf is webcrack?

Webcrack is a tool for reverse engineering JavaScript. When developers publish websites or web apps, they often shrink and scramble their code to make it load faster and harder for others to copy. Webcrack takes that mangled, hard-to-read code and attempts to reconstruct it into something that looks like the original source code, making it readable again. The tool handles several types of code transformation. It can reverse obfuscation from a popular service called obfuscator.io, which intentionally scrambles code to protect it. It can also "unminify" code, expanding condensed formatting back into something readable. Additionally, it can unpack bundled files from tools like webpack and browserify, which combine many separate source files into one large file for deployment. The tool automatically detects what was done to the code without requiring manual configuration. Security researchers, developers debugging third-party code, and anyone trying to understand how a website or web app works under the hood would find this useful. For example, if you're investigating a suspicious script embedded in a webpage, or trying to understand how a competitor's widget functions, you'd run the code through webcrack to get a cleaner, more understandable version to study. You can use it through a command line interface, as a library in your own JavaScript projects, or try it online through a web-based playground. The project is built in TypeScript and emphasizes performance and safety, it considers variable references and scope to avoid breaking the code during transformation. It requires Node.js version 22 or 24 to run.
