MonkeyDev is a developer toolset for building, injecting, and deploying system extensions and custom dynamic libraries into mobile applications. It functions as an application patching tool and dynamic library injector designed to modify how mobile applications operate.
The project provides a development environment for creating system extensions and tweaks, including tools for injecting libraries into decrypted binaries to enable debugging and symbol restoration on non-jailbroken hardware. It features a command-line interface for deploying hooks into system processes and third-party applications.
Its broader capabilities cover binary modification, runtime analysis through external application debugging, and the integration of third-party SDKs. The toolset handles the compilation of system extensions and the restoration of function names in decrypted binaries.
