Decompile a Unity APK: Mono vs IL2CPP Recovery
Unity APK analysis depends strongly on the scripting backend. Managed assemblies from a Mono build and native output from IL2CPP present different recovery.

Unity APK Analyzer
Detect and analyze Unity games inside an APK, including the scripting backend (IL2CPP or Mono), assemblies, and asset bundles, to see how it's built.
Unity APK Analyzer is part of APKLint, an online toolkit for inspecting Android APK files. Detect and analyze Unity games inside an APK, including the scripting backend (IL2CPP or Mono), assemblies, and asset bundles, to see how it's built. Upload an APK in your browser to view the relevant details; results reflect what the file itself exposes.

Your privacy is the default: files you upload are processed on our servers over an encrypted connection and permanently deleted by a scheduled hourly cleanup after analysis finishes, and never shared.
What Unity APK Analyzer checks
- Detects Unity via libunity.so
- Identifies IL2CPP (libil2cpp.so + global-metadata.dat) vs Mono builds
- Locates game assets and asset bundles
- Decodes the Android wrapper and manifest
Good to know: IL2CPP compiles C# to native code; recovering original C# is not possible, though metadata reveals structure.
When to use Unity APK Analyzer
- Best for
- Confirming an APK is a Unity game and reading its scripting backend (IL2CPP or Mono), Unity libraries, and asset bundles.
- Not the right tool for
- Not for Flutter or React Native apps, and IL2CPP builds will not yield original C#.
- What you get back
- Unity filename markers, inferred IL2CPP/Mono scripting backend and a limited asset-file list. Engine/library versions are not extracted.
- How it differs from related APKLint tools
- Unlike the Flutter (Dart snapshot) and React Native (JS bundle) analyzers, this targets Unity's IL2CPP/Mono and assets.
- Limitations
- IL2CPP compiles C# to native code; metadata reveals structure but original C# cannot be fully recovered.
How to use Unity APK Analyzer
