# Hooky

> A modern C++ hooking framework for x86-64, ARM64, and RISC-V64, with cross-platform detours and function replacement.

Hooky is a cross-platform, cross-architecture function-hooking framework with a
modern C++ API. Hooks can observe full CPU context on function entry and exit,
replace functions, and call generated trampolines while retaining explicit
control over hook state.

It targets x86-64, ARM64, and RISC-V64 and fills a role similar to Frida's
Interceptor and Dobby. Internally, Hooky composes with LIEF Runtime, MCStone, and LLVM
into a portable detour engine.
