webcrack

Appearance

Introduction ​

webcrack is a tool for reverse engineering javascript. It can deobfuscate obfuscator.io, unminify, transpile, and unpack webpack/browserify, to resemble the original source code as much as possible.

  • 🚀 Performance - Various optimizations to make it fast
  • 🛡️ Safety - Considers variable references and scope
  • 🔬 Auto-detection - Finds code patterns without needing a config
  • ✍🏻 Readability - Removes obfuscator/bundler artifacts
  • ⌨️ TypeScript - All code is written in TypeScript
  • 🧪 Tests - To make sure nothing breaks

Requirements ​

Node.js 22 or 24.

Planned Features ​

  • Smarter variable renaming, possibly with LLMs like GPT-3.5
  • Support older obfuscator.io versions
  • Unpack multi-chunk bundles
  • Decompile @babel/preset-env helpers
  • Decompile TypeScript helpers, modules and enums
