Whale

Whale is a cross-platform hooking framework for intercepting and modifying functions and methods at runtime. It supports Android, iOS, Linux, and macOS across ARM, Thumb, ARM64, x86, and x86-64 architectures. On Android, it provides Xposed-style Java method hooks and can alter class or object relationships during execution. It can also bypass selected hidden API restrictions on supported Android versions. Native platforms receive symbol resolution and native hooking capabilities for lower-level instrumentation. The project is intended for debugging, hot fixes, sandboxing, monitoring, and runtime behavior modification. Some iOS hooking capabilities are constrained by platform code-signing and execution restrictions.
