An automated JavaScript deobfuscation tool built on Babel AST transforms, offering a CLI, a TypeScript API, and an online playground. It reverses common obfuscation techniques such as string-array encoding, control-flow flattening, self-defending code, and variable mangling.

Use cases

• deobfuscate obfuscated javascript code
• restore readable source from minified and obfuscated js
• remove anti-debug and self-defending code from scripts
• unflatten control flow in obfuscated bundles
• decode string arrays in obfuscated javascript
• reverse engineer obfuscated web scripts
• clean up and rename mangled variables in js

When to choose

• you need to analyze obfuscated JavaScript from web scraping or reverse engineering
• you want a CLI or programmatic API for batch deobfuscation
• you prefer an online playground for quick one-off deobfuscation
• you need to undo common obfuscator.io-style transformations

When to avoid

• you need to obfuscate code rather than deobfuscate it
• you work primarily with minified but not obfuscated code (a simple formatter suffices)
• you need deobfuscation for languages other than JavaScript
