## What it is
Synchrony is a JavaScript deobfuscator and cleaner focused on undoing obfuscation from javascript-obfuscator/obfuscator.io. It works as a CLI tool installed via npm and also offers a web interface for deobfuscating mangled files.

## Use cases
- deobfuscate javascript-obfuscator output
- clean obfuscated js files
- unmangle obfuscated javascript
- analyze obfuscated malware scripts
- reverse obfuscator.io protected code
- restore readable javascript from mangled bundles

## When to choose
- you need to reverse javascript-obfuscator/obfuscator.io output
- you want a CLI or web tool for automated JS deobfuscation
- you're analyzing suspicious obfuscated scripts

## When to avoid
- the file was produced by an old version of javascript-obfuscator
- you need configurable deobfuscation options (no user configuration yet)
- you need a general-purpose JavaScript beautifier rather than an obfuscation reverser
