Show DEV: I built a completely offline JavaScript AST IDE & Obfuscator 🛡️

#showdev #javascript #cybersecurity

Hey everyone! 👋

I have a deep interest in cybersecurity and cryptography. After recently building a QKD (Quantum Key Distribution) simulator, a Password Vault, and a Steganography tool, I wanted to dive deeper into how JavaScript code is secured and obfuscated.

So, I built CyberObfuscator Ultimate — an Enterprise-level AST IDE and JavaScript Obfuscator that runs entirely in your browser without any backend server.

✨ What makes it special?

Most obfuscators are CLI tools or rely on a backend API. I wanted to build a completely offline-safe sandbox where developers can experiment with AST manipulation securely.

Key Features include:

  • Multi-Pass Engine: A highly structured pipeline (Parse → Analyze → Normalize → Transform → Optimize → Generate).
  • Advanced Protection: Applies Scope-Aware Renaming, Dynamic Base64 String Pooling, Numeric XOR Encoding, Control Flow Flattening, and Anti-Debugging.
  • Dynamic Custom Plugins: You can write and inject your own custom AST transformation plugins directly in the editor using Babel plugin syntax!
  • Pro UI: Draggable Dockview layout, Command Palette (Ctrl+Shift+P), multiple themes, and a build telemetry dashboard.

🛠️ Tech Stack

I built this using Vanilla JavaScript, HTML, and CSS. Under the hood, it uses:

  • Babel Standalone (AST parsing and manipulation)
  • Monaco Editor (Code editing)
  • Dockview Core (Panel layout)

I would love for you to try it out, break it, and share your feedback! What kind of obfuscation passes should I add next?
