Modder Hub

Modder Hub is a comprehensive Android reverse engineering and modification toolkit built for developers, security researchers, and modding enthusiasts who need to deconstruct, analyze, and repackage applications.

The app delivers a full suite of specialized tools for working with APK files, DEX code, native libraries, and system resources. Convert Java to Smali with real-time compilation, decompile and recompile binary XML files, generate custom notifications and dialogs, and work with encryption and obfuscation at scale. The base converter handles decimal, hexadecimal, octal, binary, and ASCII transformations, while the integrated Java console provides immediate feedback during code modifications. APK signature verification can be analyzed and adjusted using multiple hook methods, and the dex string encryption tools help protect sensitive data within compiled applications.

For those working on larger projects, the app includes batch operations across multiple files. Clone any APK, extract contents to directories (including support for .apks bundles), and process jar files, class files, and native ELF binaries. The smali-to-dex converter, dex splitter, and batch deletion tools streamline repetitive workflows. Generate custom signing keys in pk8, pem, and jks formats, then apply them using a unified signing scheme that supports v1, v2, and v3 protocols. Image-to-base64 conversion, database-to-JSON transformation, and text comparison utilities round out the free toolkit.

Premium features unlock advanced capabilities for production workflows. Floating and iOS-style dialog patchers let you inject custom interfaces into existing applications, while the update dialog system pushes real-time mod notifications to users. The login interface maker enforces one-device, one-app, one-key authentication, and the custom dialog server provides pre-built templates for common scenarios. GitHub integration allows you to upload modified projects directly to repositories, and the plugin publishing system lets you share custom tools with the global modding community.

The app includes built-in tutorials, video guides, and a growing reference library of online Java code samples to help you learn smali language fundamentals and reverse engineering principles. View live exceptions during target APK runtime through logcat injection, and analyze detailed device information to troubleshoot compatibility issues.

Modder Hub requires Android 5.0 or higher and is optimized for educational and analytical use. Whether you're learning app modification, analyzing security mechanisms, debugging your own applications, or customizing existing functionality, this toolkit provides the depth and breadth needed for serious reverse engineering work.
