## What it is
Obfuscapk is a modular Python tool that obfuscates Android APKs and App Bundles in a black-box fashion, without needing source code, by decompiling with apktool and transforming smali code, resources, and manifest. It supports extensible obfuscation techniques via a plugin-style architecture.

## Use cases
- obfuscate an android apk without source code
- make an app look different to signature-based antivirus
- apply obfuscation techniques to smali code
- test malware detection against obfuscated android apps
- extend an obfuscation tool with custom techniques
- obfuscate android app bundle aab files

## When to choose
- you need black-box APK obfuscation without original source code
- you want a modular tool you can extend with new obfuscation techniques
- you need to generate obfuscated app variants for research or testing

## When to avoid
- the project is archived and no longer maintained
- you need actively supported obfuscation with recent Android versions
- you need app bundle obfuscation on Windows (unsupported)
- you want source-level obfuscation of your own codebase
