Apktool vs Qiling Framework

Apktool is a command-line tool for reverse engineering Android APK files. It can disassemble an app’s resources into a form close to their original structure, then rebuild an app after changes such as translation or permission edits. Its analysis mode attempts to extract resources and the manifest for inspection without rebuilding. Apktool runs on Windows, Linux, and macOS; its official installation guide describes wrapper-script steps for those systems and requires Java 8 or later. Decode options include choosing resource-resolution behavior, skipping resources or source disassembly, and setting a framework directory. Build options include selecting an aapt2 binary, adding a generic Network Security Configuration file, and disabling APK repacking. The Apache license permits redistribution, modification, and integration into another project. Apktool is free, with no pricing tiers stated. Its FAQ says Android devices are not officially supported, and some OEM-modified “Magic APKs” may not decode or build. Builds are unsigned; copying a signature retains only the original APK signature v1 scheme.

Qiling Framework is free software for emulating and instrumenting binaries for reverse engineering and security analysis. It runs machine code in an isolated environment and supports debugging across architectures and platforms. Listed architectures include x86, x86_64, ARM, ARM64, MIPS, and 8086; supported formats include PE, Mach-O, ELF, and COM. Hooks can observe instructions, basic blocks, memory access, exceptions, system calls, and I/O. APIs provide access to registers, memory, filesystems, operating systems, debugging, and execution-state saving and restoration. Qiling can also hot patch running code, including loaded libraries. Its IDA Pro plugin can emulate binaries in IDA, display live context, run scripts, save and load snapshots, and deobfuscate code. Qiling uses Unicorn for CPU emulation and adds operating-system awareness, executable loading, dynamic linking, and syscall and I/O handling. Installation options include pip, source, and Docker. It is licensed under GPL version 2 or a later version at the user's option. Some syscalls or operating-system APIs may not be implemented, and users may need to implement or map them.
